3. SAFETY INFORMATION
WARNING: Caution: Note: Safety Regulations
Means there is the possibility of personal injury to you or others. Means there is the possibility of damage to the device. Provides information to further assist in the use of the device.
Surveyor Central and Surveyor Central Repeater are medical devices labelled, according to European directive 93/42/EEC (MDD), as a class IIb and class I medical devices respectively. Telemetry transmitters are produced by Welch Allyn, and marked per the MDD directive. Various other accessories, like the monitor and printer are marked by the respective manufacturers according to the applicable European directives. See respective declarations of conformity for details. Surveyor Central cannot be classified as Medical Electrical Equipment according to the definition of safety standard IEC 60601-1. The Surveyor Central, together with all accessories that have a physical or logical connection with it, forms part of a Medical Electrical System. The Surveyor Central complies with various safety and performance regulations as mentioned in Appendix E.
Warnings This manual gives important information about the use and safety of this system. Deviating from operating procedures, misuse or misapplication of the system, or ignoring specifications and recommendations could result in increased risk of harm to users, patients and bystanders, or damage to the system. Users are expected to be licensed clinical professionals knowledgeable about medical procedures and patient care, and adequately trained in the use of this system. Before attempting to use this system for clinical applications, the operator must read and understand the contents of the user manual and other accompanying documents. Inadequate knowledge or training could result in increased risk of harm to users, patients and bystanders, or damage to the system. Contact Welch Allyn service for additional training options. The Surveyor Central is not designed to be used in the environment where the patient is undergoing a medical procedure as defined in IEC 60601-1 (1.5 m from the patient). The use of an isolation transformer between mains and Surveyor Central is required but is not a sufficient safety measure for use in the patient environment because of data connections (data network) that might cause excessive leakage currents in some conditions. Additional separation devices may be required. Any equipment that has a physical connection between Surveyor Central and that is in the patient environment must have additional protection against electrical shock (e.g., a separation device between the equipment and Surveyor Central) in order to be in compliance with IEC 60601-1 or equivalent safety standards. The Surveyor Central is not battery operated. For uninterrupted use, an appropriate uninterruptible power supply (UPS) is required. The WiFi network (telemetry) as well as any active network components such as switch and firewall should also have the capability to remain operational in cases of general power outages. The Surveyor Central is designed to continue operation with the last stored settings after a power interruption, however, loss of stored data is possible if power is interrupted to the system that stores the data. When using a backup power source such as a UPS, periodically check it to ensure it is properly functioning per the manufacturer’s recommendations and specifications.
Page | 7
SAFETY INFORMATION In order to be safely used, all accessories (such as monitors, printers, data network, etc.) must be compatible, and comply with all safety and EMC regulations that apply to them according to their intended use; for use in Europe, these accessories should be CE marked. The various parts of a Surveyor Central monitoring system (Telemetry receiver computers, control and display computers, storage computers, printers, or bedside monitors) are all connected through a specific Ethernet data network. This network must be installed according to all applicable standards and may only be logically or physically connected to the outside world through a specific routing device available from Welch Allyn. Any other data path can lead to serious security risks and interruptions of monitoring. Other devices must not be connected to the Surveyor data network. Connection of the Surveyor Network along with its associated transmitters and monitors to the IT Network in a healthcare delivery organization may carry risks to patients, operators as well as 3rd parties. Such risks must be carefully assessed and mitigated. The IEC 80001-1:2010 standard provides guidance to the healthcare delivery organization for carrying out such risk assessment and mitigation. Changes to the IT Network can also introduce new risks which should be carefully assessed and planned. The Surveyor Central, as all medical equipment or systems, needs special precautions regarding EMC and needs to be installed and put into service according to the EMC information provided in the installation procedure in order to obtain a sufficient degree of immunity as well as not to create disturbance to other equipment. Refer to the specific EMC instructions in this manual. In the case of a Surveyor Central system with additional control stations for display and control of the same patient channels in multiple locations, silencing or suspending of alarms will cause the alarm to be silenced or suspended at all the locations. Be certain that alarms are silenced or suspended by the clinician having direct responsibility for care of the given patient. Cleaning must be performed with the system turned off. Let all parts dry well before turning the power back on. Install all computer equipment with adequate space around ventilation vents. Clean and remove accumulated dust on ventilation openings, and also remove dust regularly from the inside of the system. The last operation must be performed by adequately trained and authorized personnel, and with the system turned off. Install the computer that generates the alarm sounds in such a way that the sound can be heard adequately in the appropriate areas. The speaker is installed on the front panel of the computer. The Surveyor Central provides an alarm volume adjustment. Be sure to set the volume at a level that alarms can be heard above the ambient noise level in the environment of use. Setting alarm volumes too low can impede recognition of alarm signals. The hardware watchdog device is connected to the computer with a USB cable and has its own power supply. Mount it in such a way that the sound can be heard adequately in the appropriate areas. Test regularly by temporarily removing the USB plug while the central station power is turned on. The Surveyor Central must be connected to a properly grounded power terminal, and the electrical installation must comply with the local safety requirements for the environment where it is used. The Surveyor Central requires more than one mains outlet. Fix multi-socket outlets properly, do not leave them on the floor, and organize the cabling in such a way that normal work is not hampered and safety is not compromised. Regularly check all mains power cables for damage and proper connection. Do not use equipment with a damaged power cord. Page | 8
SAFETY INFORMATION The Surveyor Central components are not waterproof. Avoid spillage of liquids from penetrating the system or submersion of components and transmitters into a liquid. In case of accidental spillage, turn device off and let dry thoroughly. The various manufacturers of accessories provide separate user manuals (e.g., monitor, laser printer, Surveyor S12/S19, Surveyor S4, patient cables, electrodes). Read these manuals well and refer to them for specific functions. It is recommended to keep all manuals together. Refer to these manuals for a list of approved accessories. When in doubt, contact Welch Allyn. Every hardware or software modification has to be made by Welch Allyn authorized and trained technical personnel. Do not disassemble the equipment as hazardous voltages may be present within. Contact Welch Allyn or an affiliated service representative for repairs. Technical and service documents are available upon request. Always turn the system off before connecting or disconnecting any cables. Do not use the system in places that are susceptible to explosion hazard or in the presence of flammable gases. Do not use the system in the presence of Magnetic Resonance Imaging (MRI) equipment and tomography equipment. Do not insert a bootable CD/DVD on the Surveyor Central computers. Do not run any program from CD/DVD or USB memory sticks. These I/O devices should only be used for export and import of patient ID formats, profiles and protocols. Surveyor Central computers contain a small lithium battery for maintaining clock and BIOS settings which should normally last the lifetime of the system. If the battery needs to be replaced, be sure that it is done by qualified personnel and with a battery of the same type. Surveyor Central software has been extensively tested and clinically validated. Several protection mechanisms against software errors have been built into the Surveyor Central; however, in the unlikely event of a failure of the software or the computer processor, the electronic (hardware) “watchdog” of the Surveyor Central sounds a continuous loud beep and the Central station has to be power-cycled to remove this. Please inform Welch Allyn service personnel for further troubleshooting should this continuous loud beeping occur. Surveyor Central hardware has been carefully selected for reliability; however, in mission critical situations, it might be advisable to have a backup system available at short notice. This also includes accessories such as patient transmitters and monitors which, by nature and way of use, can be more prone to failure. Installation and connection to data networks must be performed by properly trained personnel, authorized by Welch Allyn, Inc. To maintain designed operator and patient safety, use only parts and accessories supplied with the system and available through Welch Allyn, Inc. The equipment described in this manual has an expected lifetime of five years from the date of manufacture. Operation beyond this expected life may not meet specifications. This lifetime is only valid if devices are used according to the instructions in this manual and associated manuals provided with the equipment. Page | 9
SAFETY INFORMATION The system captures and presents data reflecting a patient’s physiological condition that when reviewed by a trained physician or clinician can be useful in determining a diagnosis. However, the data should not be used as a sole means for determining a patient’s diagnosis. The system is optionally equipped with Welch Allyn’s VERITAS™ 12-lead resting ECG interpretation algorithm. When this option is enabled, the VERITAS ECG algorithm can provide an over-reading physician with a silent second opinion through diagnostic statements output on the ECG report. For additional information on the Welch Allyn VERITAS 12-lead resting ECG interpretation algorithm, please refer to the Physician’s Guide to ECG Interpretation. 12-lead ECGs acquired through Surveyor Central or attached monitors will normally use a modified lead system with the limb electrodes positioned on the torso. Although this is a generally accepted practice (e.g., in stress testing), the different electrode positions can cause morphology changes on the ECG, thus influencing their interpretation. Most frequently seen differences are a vertical and rightward axis shift, minor changes of evidence of old inferior infarction and changes in the T-wave in the limb leads. All 12-lead ECGs printed with Surveyor Central have a warning message that alerts the physician that the ECG might have been acquired with torso positioned limb leads. It is recommended that you place the electrodes as close as possible to the normal limb positions avoiding the possibility of causing artifact. The right arm and left arm electrodes should be placed on the clavicles as close as possible to the arms. The left leg electrode should be placed as close as possible to the left leg without subjecting it to the possibility of motion artifact. The minimum amplitude for detecting QRS complexes is user selectable between 160, 300 and 500 µV. A low value of this limit has the risk of detecting P waves as QRS complexes in the case of atrio-ventricular block; however, a high value might lead to false cardiac arrest alarms if the QRS amplitude is low in all leads. Therefore, the user is encouraged to select detection leads with amplitude of at least 1 mV and set the minimum QRS amplitude at 300 µV. During periods of lead fail and when a reduced lead set is used for patient monitoring, 12-lead resting ECG interpretation cannot be reliably used in determining a diagnosis. When the 40 Hz filter is used, the frequency response requirement for diagnostic ECG equipment cannot be met. The 40 Hz filter significantly reduces high-frequency components of the ECG and pacemaker spike amplitudes, and is recommended only if high-frequency noise cannot be reduced by proper procedures. The quality of the signal produced by the system may be adversely affected by the use of other medical equipment connected to the patient including, but not limited to, defibrillators and ultrasound machines. If the system or one of its subsystems become inoperable during monitoring, a medium or low priority type alarm sounds and a message is displayed on the screen. In case of hardware or software failure that causes the sound generator or display subsystem to fail, the hardware watchdog unit generates a continuous beep. Periodic checks of the monitoring screen are recommended to ensure proper functioning. The LCD supplied with the Surveyor Central has a separate power switch and power-on indicator. If no image appears on the screen, check the LCD power indicator. Alarm sounds are not affected by the status of the LCD. Do not connect a sound-capable display monitor such as a LCD TV to the Surveyor Central. The on/off switch of the Surveyor Central is deactivated and can only be used for emergency power down by depressing it for a period greater than 4 seconds. Normal shutdown of the Surveyor Central should be done by using the password-protected configuration window. Do not use excessive force on any of the connection cables and handle all accessories with care. Various alarm conditions require operator set limits that vary per patient. For telemetry monitoring, Surveyor Central supports the selection of appropriate alarm profiles when a patient is admitted. The operator should check these settings after each patient admission to ensure whether the chosen alarm limits are appropriate for the individual patient. Inappropriate alarm limits render the alarm system useless. Page | 10
SAFETY INFORMATION Saved profiles are only applicable to the type of cable and detection leads in use when the profile was defined. If another type of cable is used with a saved profile, the default detection leads will be utilized. In any single environment such as an intensive care unit or cardiac operating theater, a potential hazard can exist if different alarm preset values are used for the same or similar equipment. Portable and mobile RF communications equipment can affect medical electrical equipment or systems as well as the Surveyor Central and its accessories. Surveyor Central alarms can only be silenced and not reset. This means that visual representation of an alarm condition remains present after an operator silenced action until the alarm condition disappears (unless obscured by another, higher priority, alarm). The auditory alarm signal does not re-activate after a silence action if the alarm condition remains the same. As soon as the alarm condition of a silenced alarm goes away, the alarm can be reactivated. The Surveyor Central alarm system can be globally disabled or suspended for a period of time for a patient. The selection between disabling and suspending, as well as the suspension duration, can be set in the passwordprotected system configuration page. A clear visual indication of this condition is present in the patient window, and a reminder signal sounds every three minutes. Any technical alarms will be visually presented on the screen, regardless of the alarm disabled state. In this configuration the technical alarms will not be audible. The intended use of Surveyor Central Repeater is to repeat waveforms, parameters and system status of selected patients monitored by Surveyor Central in order to enhance workflow for medical personnel. Surveyor Central Repeater does not produce audible alarm signals and may not be used to substitute any alarm functions of Surveyor Central. This manual applies to the most recently manufactured system, with respect to software release and hardware configuration. Whenever used for software upgrades on previously installed equipment, some technical specifications or labels may not be respected, whereas functions and instructions for use of the system are always valid. This user manual reflects software version 5.1.0. The following warnings concern telemetry monitoring: Electrostatic discharges may generate short interference on the ECG tracings. WiFi Telemetry: The Surveyor S4 utilizes standard WiFi telemetry per the IEEE 802.11g/n standard. The WiFi network supporting the Surveyor S4 and for use with the Surveyor Central must be installed and tested in accordance to Welch Allyn’s guidance and network requirements. Also refer to Welch Allyn’s Manufacturer Disclosure Statement for Medical Device Security (MDS2) documents for the Surveyor Central and Surveyor S4. Welch Allyn and/or 3rd party partners are available to perform network site surveys and audits to confirm the suitability of the facility’s WiFi network for use with the S4 mobile monitor and connection to the Surveyor Central and its Surveyor Network. The system was not designed to be used with high frequency (HF) surgical devices. Use of transmitters and monitors may be restricted in some countries; see the transmitter’s and monitor’s user manuals for details. Consult the Surveyor S12/S19 and Surveyor S4 user manuals for more information regarding the patient cable, electrode recommendations, cleaning, maintenance, channel frequencies, precautions to take during patient defibrillation, and other warnings. The following warnings concern pulse oximetry (SpO2) telemetry monitoring: Pulse oximetry sensors must be checked a minimum of every 4 hours and moved to a new site as necessary. Page | 11
SAFETY INFORMATION Pulse oximetry sensors are susceptible to high ambient light interference including ambient photodynamic therapy. Shield the sensor area as necessary. SpO2 measurement may be adversely affected by dyes (e.g., methylene blue, indocyanine green, indigo, carmine, fluorescein) introduced into the bloodstream. Any condition that restricts blood flow such as the use of a blood pressure cuff or extremes in systemic vascular resistance may cause inability to determine accurate SpO2 readings. Certain conditions such as physical movement (patient and imposed motion); diagnostic testing; low perfusion; electromagnetic interference; electrosurgical units; dysfunctional hemoglobin; and inappropriate positioning of the pulse oximeter sensor may result in pulse oximetry readings that are unreliable. SpO2 signal inadequacy is indicated by error messages displayed on the LCD of the transmitter and by alarms generated at the Surveyor Central system for signals coming from the transmitter. The performance of the monitor may be compromised by excessive motion. Nail polish and/or artificial fingernails can affect the accuracy of pulse oximetry and should be removed. The pulse oximeter equipment is calibrated to display functional oxygen saturation. Functional SpO2 testers (simulators) are useful to measure how accurately a particular monitor is reproducing the calibration curve but cannot be used to assess the accuracy of a type of probe or monitor. If there is independent demonstration that a particular calibration curve is accurate for the combination of a pulse oximeter monitor and a pulse oximeter probe, then a functional tester can measure the contribution of a monitor to the total error of a monitor/probe system. The functional tester can then measure how accurately a particular pulse oximeter monitor is reproducing that calibration curve. If no SpO2 or pulse rate is present, alarm conditions are provided at the Surveyor Central system. There is no alarm condition provided at the transmitting device. For additional instructions and warnings, refer to the user manual of the transmitting device. The following warnings concern heart rate for telemetry monitoring: Heart rate indication is usually not affected by ventricular or supraventricular arrhythmias or irregular heart rates. Heart rate is calculated over 16 beats at rates over 40 bpm and 4 beats at lower heart rates. This results in a response time of 9 seconds or less when the heart rate changes suddenly from 80 bpm to 40 or 120 bpm, as measured according to IEC 60601-2-27. High heart rate and low heart rate alarms cannot be disabled. Tall and peaked T-waves may affect QRS detection resulting in doubled heart rates. Surveyor Central rejects tall T-Waves less than or equal to 230% of a 1 mV QRS measured according to IEC 60601-2-27. The heart rate meter correctly detects all beats of the alternating beat type waveforms considered in IEC 60601-2-27, Figure 201.101, patterns A1-A4, if the QRS amplitudes exceed the minimum detection threshold set by the user. Time to low heart rate, high heart rate and asystole, as measured according to IEC 60601-2-27, is lessthan 10 seconds. Heart rate indication is not reliable during episodes of ventricular fibrillation. Page | 12
SAFETY INFORMATION
The summarized performance of the QRS recognition and classification algorithm on standard databases, as defined by ANSI/AAMI EC 57, is as follows:
Performance Measures QRS Detection Sensitivity % QRS Detection Positive Predictivity % PVC Detection Sensitivity % PVC Detection Positive Predictivity % PVC Detection False Positive Rate %
MIT Database Welch Allyn 99.93 99.87 95.13 97.04 0.220

AHA Database Welch Allyn 99.78 99.91 93.15 98.40 0.154
Because of noise, artifact and the many different physiological manifestations of the ECG signal, it is inevitable that some beats are not detected or correctly classified by the system. The user is advised not to rely completely on automatic alarm systems for the monitoring of critical patients. Excessive patient movement could interfere with the operation of the system. Proper patient preparation is important to proper application of ECG electrodes and operation of the device. If the ECG amplifier input is out of normal operating range, the display will indicate a lead fail for the lead(s) where this condition is present and if the signal is being displayed or printed, the respective lead(s) will print out as square waves. A lead fail alarm is generated on the Surveyor Central. The following warnings concern pacemaker patients for telemetry monitoring: Rate meters may continue to count the pacemaker rate during occurrences of cardiac arrest or some arrhythmias. Do not rely entirely upon heart rate meter ALARM SIGNALS. Keep pacemaker PATIENTS under close surveillance. See this manual for disclosure of the pacemaker pulse rejection capability of this instrument. With the Surveyor S4 when used with the 4-wire, 5-wire or 10-wire ECG cable, all pacemaker spikes are rejected per the IEC 60601-2-27 standard (0.1 - 2 msduration, 2 - 700 mV amplitude). Signals are recognized as pacemaker spikes when they have a slew rate over 4 V/s, as measured according to the IEC 60601-2-27 standard. Abnormally high or wide pacemaker spikes might be recognized as QRS if their amplitude and pulse width exceed these values. With the Surveyor S4 when used with the 3-wire ECG cable, pacemaker spikes are not rejected consistently. For this reason, do not rely upon heart rate meter ALARM SIGNALS, when using a 3-wire cable. Welch Allyn does not claim, verify, or validate support for all available pacemakers. Consult the Surveyor S12/S19 User Manual for a description of its pacemaker spike rejection capabilities. The Pacemaker Rejection software can be deactivated by the user. This should not be done for patients with a pacemaker or suspected to have a pacemaker implanted because this can lead to a heart rate indication and failure to alarm for cardiac standstill.

SAFETY INFORMATION Other than the influence on beat detection as stated above, there is no known safety hazard if other equipment, such as pacemakers or other stimulators, is used simultaneously with the system. Notes Surveyor Central contains electronic records including ECG’s which can be exported to other applications. The Surveyor Central system can be part of a system that is compliant with the electronic records requirements of part 11 of Title 21 of the Code of Federal Regulations; Electronic Records; Electronic Signatures (21 CFR Part 11) as stipulated by the US Food and Drug Administration's (FDA). The user of the Surveyor Central system must ensure full compliance to this as required. Compliance with applicable privacy and data protection guidelines, such as HIPAA in the United States and Directive 95/46/EC of the European Parliament and the Council, plus any other local regulations and policies are the ultimate responsibility of the entity deploying and using the Surveyor Central. The Surveyor Central system implements certain features such as username/passwords and audit trails. By-design, the system is accessible and available for use upon power-up. The facility deploying and using the system is responsible for ensuring appropriate safeguards are put in place to protect patient health information (PHI). This includes a mixture of physical and IT-based mechanisms to secure PHI from unauthorized access. The Surveyor Central Station including printers generating reports must be placed in a physical location that is secure (e.g., nurse’s station). Surveyor Review and Repeater stations may be placed in less secure locations but must implement proper username/password access policies as required. Page | 14

5. ELECTROMAGNETIC COMPATIBILITY Electromagnetic compatibility (EMC) with surrounding devices should be assessed when using Surveyor Central. An electronic device can either generate or receive electromagnetic interference. Testing for electromagnetic compatibility (EMC) has been performed on a representative Surveyor Central configuration, which included an Uninterruptable Power Supply (UPS) and was executed according to the international standard for EMC for medical devices (IEC 60601-1-2). This IEC standard has been adopted in Europe as the European Norm (EN 60601-1-2). WARNING: Surveyor Central should not be used adjacent to, or stacked on top of other equipment. If Surveyor Central must be used adjacent to or stacked on top of other equipment, verify that Surveyor Central operates in an acceptable manner in the configuration in which it will be used. Fixed, portable, and mobile radio frequency communications equipment can affect the performance of medical equipment. See table for recommended separation distances between the radio equipment and Surveyor Central. WARNING: The use of accessories and cables other than those recommended by Welch Allyn may result in increased emissions or decreased immunity of the transmitter.

The Surveyor Central can perform telemetry monitoring using the Surveyor S4 integrated with the healthcare delivery organization’s WiFi network infrastructure. The Surveyor Central is also designed to communicate with the Surveyor S12/S19 multi-parameter patient monitors.
Its intended functions include: Real-time, 3-wire (1-lead), 5-wire (7-lead) and 10-wire (12-lead) diagnostic ECG signal display Real-time SpO2 plethysmographic waveform display Automatic monitoring of arrhythmias, SpO2 values, and ST changes including one or more displayed waveform channels for each patient Visual and audible alarms of events, arrhythmias, and set parameters with adjustable priorities Averaged and reference QRS complexes Graphical trend review Single lead or any combination of leads up to 12 for ECG rhythm and report printing ECG signal and SpO2 data storage with optional full-disclosure storage and review When the patient device is a Surveyor S12/S19 monitor, additional parameters may include non-invasive blood pressure (NIBP), impedance respiration, invasive pressures (P1-P4), Temperature (T1, T2), end-tidal and inspired CO2, and cardiac output (CO).
Through telemetry, patients using ambulatory transmitters are monitored while moving in a designated area. To guarantee proper signal transmission in various situations, install an antenna network as per facility requirements.
The Surveyor Central Station communicates with the Surveyor S12/S19 patient monitors through a Local Area Network (LAN) interface. The Surveyor Central network can distribute patient data to one or more Surveyor Central control stations in a single or dual display mode.
Each Surveyor Central receiving workstation will acquire data. Connect multiple Surveyor workstations to the same Surveyor Central network to allow realtime patient monitoring in a variety of different system configurations (see following page).
Control, viewing, receiving signals, and data storage are all possible on a single Surveyor Central workstation. Control, viewing, receiving signals, and

INTRODUCTION data storage can also be achieved using separate workstations for each function--or a combination of functions--on the Surveyor Central network. Networked printers are used for automatic or manual printouts of 12-lead ECG, ECG rhythm, plethysmographic waveform with % SpO2 and pulse rate, and reports. An optional redundant storage server is available for increased storage capacity as well as storage to duplicate data disks when continuous and complete ECG capture is critical. This is valuable for institutions that collect ECG data for research purposes. This capability may also be important for other medical facilities. The Surveyor Central system provides the means for users to manage patient records with associated patient demographics and assign each to a particular patient monitor or telemetry system for obtaining physiological information. Physiological data obtained from patient monitors and telemetry devices are viewable and stored continuously with a minimum storage timeframe of 72 hours. Alarm monitoring and management, including definition of alarm limits, as well as data trending and reporting are available. Full disclosure supports review of the data on a particular patient including review of 12-lead ECG waveforms and other data and waveforms for obtained parameters.

Keyboard/mouse switch: Allows one keyboard and mouse to control up to 4 nodes, with their displays configured to seamlessly produce one large virtual desktop. Surveyor Central control station: A workstation with single or dual display on the Surveyor Central network for purposes of controlling and viewing a set of monitored channels at a designated location within the facility. Surveyor Central receiving station: A workstation connected to the healthcare delivery organization’s WiFi network through a firewall router for the purposes of receiving transmitted signals from Surveyor S4. As required, the receiving station produces a set of channels for viewing or storage at another location on the Surveyor Central network. Surveyor Central receiving and control station: A workstation with single or dual display connected to the transmitters and monitors for purposes of receiving transmitted signals to produce, display, and control a set of monitoring channels. Data storage is accomplished at another location on the Surveyor Central network. Redundant data storage: Stores real-time data and simultaneously copies the data to a set of Redundant Array of Independent Disks (RAID) for increased storage capacity and data security in situations where complete data collection is critical. All system data storage for workstations on the Surveyor Central network is performed at this networked server when it is a component of the Surveyor Central. Surveyor Central repeater station: A display station where monitoring channels are repeated and can be displayed, printed, and reviewed. Alarms are visual only and are not audible or controlled at the repeater station. Network printer (print server): The printer must be plugged into the AC power outlet through the appropriate power cord that is in compliance with local regulations. Please refer to the printer manufacturer’s user manual for information, warnings, commands, and intended use. Page | 23
INTRODUCTION System Software Options Full disclosure for continuous data storage: All patient monitoring data is available for review when this option is enabled. The storage amount is dynamic and relies on the number of channels utilized in relation to the size of the storage space. Each day of a patient’s data is equal to approximately 0.5 GB. Divide number of storage days by number of monitored patients to calculate number of days for each monitored patient (i.e., 600 days of storage ÷ 10 monitored patients = 60 days per patient). This option also allows off-line archive to a network directory or DVD media. Data can be acquired by Welch Allyn’s HScribe™ Holter analysis system for further review, rhythm quantification, Holter reporting, and/or 12-lead ECG collection which can then be exported in XML or Unipro format. When this option is not enabled, one minute of ECG data surrounding each event or alarm is stored for review, ECG printing, and export. Protocol manager: Only available for Telemetry channels. Allows the clinician to design automatically-timed reminder events, automatically generate printed ECGs, and/or export resting 12-lead ECGs. This is particularly useful to clinicians that perform ECG data collection and must remember to execute certain functions at specific times. The application allows the clinician to program the times for such events to automatically occur. Several different protocols can be designed and the desired protocol can be selected during the patient monitoring sessions. Protocols can also be programmed in phases started by the Surveyor Central station user or by pressing the call button on the transmitter. Extended arrhythmia and 12-lead ST monitoring: In addition to standard lethal arrhythmia events and alarms, this option allows the clinician to automatically print and capture ventricular ectopy, rhythm patterns, and QRS changes as well as pacemaker failure events. This feature also allows averaged 12-lead ECG display for comparison of the reference ECG superimposed on the current ECG. The reference ECG is used for ST change alarms. Note that not all extended arrhythmias are available with S12/S19 patient monitors. Resting ECG interpretation: Enables global ECG measurement including QT/QTc calculation and 12-lead ECG interpretation utilizing Welch Allyn’s VERITAS algorithm. 12-lead ECGs can be exported in Unipro format to a network directory or directly to Welch Allyn’s E-Scribe™ data management system. This option is required to enable the ability to use and define E-Scribe custom ID formats. This feature is optional with telemetry only monitoring channels. This feature is always included with Surveyor S12/S19 patient monitoring or a mix of telemetry and S12/S19 patient monitoring. Review station: Enables patient data review in the Surveyor Central from the online database, as well as patient monitoring data archived from the database to external media. The (separate) Resting ECG Interpretation option is required to enable global measurement and 12-lead ECG interpretation onarchived records. The Surveyor Central review station screen layout is similar to the Surveyor Central review screen in dual-display modality and has the same functionality as the Surveyor Central review features including printouts and export. When networked to the Surveyor Central database, it is possible to initiate archive of patient monitoring data. Please refer to the Surveyor Central Review Station user manual (PN 9515-169-75-ENG) for more detail. Page | 24

When configured with optional 10-wire ECG, the S4 provides continuous 12-lead ECG transmission. Refer to the diagram in this section.
Surveyor Central Network The network for the Surveyor Central allows for the connection and exchange of data between the system components. Ethernet cable is used to connect all devices to the multi-port switch through an internal or external wall connection. All devices are outside of the patient area. WARNING: Do not connect the Surveyor Central Network to computers, devices other than those specified by Welch Allyn, or the Internet, as system operation may be impaired. Consult Welch Allyn or one if its affiliates for information on devices that are approved for use on the Surveyor Central Network. Surveyor Central’s security router is used to isolate the system from the institution network. A secure firewall router is used for any repeater stations or review stations that are located outside of the Surveyor network. Other applications that access Surveyor Central such as Surveyor Import for Holter analysis and remote service support are networked in this way.

Privacy Information The equipment described in this manual is compliant with European directives 95/46/EC and 2002/58/EC on the protection of personal data. Welch Allyn, Inc. or its representatives cannot be considered the “data controller” in the sense of these directives, neither as responsible for processing this data. These functionalities will need to be assigned within the structure of the user organization. It is therefore the duty of the customer to provide the correct storage and handling of data, putting into service all measures foreseen in the mentioned directives or its national implementation. In particular, it is the duty of said customer to regulate access to the parts of the equipment described in this manual that might disclose information concerning a specific identified patient, taking those measures that he considers most suitable to obtain what is mentioned in the directives, providing, for example, rooms with limited access and/or a system of identification for access to the information. The following information is meant to help the user decide which measures to take, taking into account both patient safety and the protection of personal information. Surveyor Central allows the possibility to enter patient name as part of the demographic data. This name can be displayed on the screen of the system, depending on the configuration settings. The name is always displayed on all printouts. Surveyor Central contains a temporary storage area of patient data (including patient name, if entered) meant for review in the context of immediate care, to which access is possible only through Surveyor Central components through the Surveyor data network. It is also possible to copy the data from a monitoring session (including patient name, if entered) to an off-line storage location or device. This data can only be read through specific Welch Allyn software for the purpose of reviewing this data, e.g., on a Holter analysis system or a Surveyor Central review station. It is the responsibility of the user organization to regulate access to these systems and software in compliance with local regulations.

7. USING THE SYSTEM Turning on the Surveyor Central Workstation The ON/OFF switch is located on the front side of the CPU. When switch is depressed, the workstation will power on. To turn on LCD screen, locate the main switch (usually on the bottom border of the screen). NOTE: The power-up sequence takes about 2 minutes and then the main display appears. NOTE: Always keep the monitor ON/OFF switch in the ON position. If the monitor’s indicator light is not illuminated, press the monitor ON/OFF switch. If the monitor indicator light is illuminated orange, red, or blinking and the monitor is still blank, check the cable connections between the monitor and the base. If an issue persists, contact Welch Allyn, Inc. technical support personnel. Display Screen The Surveyor Central screen is divided into sub-screens, each showing a single patient. The number of traces that are shown depends on how the system is configured. This screen is called the “multi-patient display”. An example is shown in Figure 7. In the multi-patient display, the entire screen displays real-time status of all connected patients including waveforms sent from monitors and/or telemetry transmitters. NOTE: Normally, the waveform traces are drawn smoothly and continuously. Occasionally, you may observe a brief halt followed by the waveform catching up. This is usually due to momentary communication delays through the network between the Surveyor Central and the monitors/transmitters. The system is designed to work through such delays without data loss. However, if this occurs frequently, contact your network administrator or Welch Allyn to check the condition of the network.

USING THE SYSTEM Moving the Cursor The on-screen arrow is the mouse cursor used to activate all functions. For example, if you want to acknowledge and silence an alarm, move the cursor with the mouse over the Event/Alarm button (only visible if there is an alarm present) and left click the mouse button. It is not possible to acknowledge and silence alarms from a Surveyor Central repeater station, with the exception of protocol alarms. Multi-patient Display Buttons Buttons in the lower right area of the multi-patient display are active and can be selected by a left mouse click. Show 10 mm/s is used to toggle all monitored ECG waveforms between 25 mm/s and 10 mm/s speed for all patients. Patients will open a window that allows pre-admission entry of patient demographics. This window also shows the status of the current monitored patients. Patients is not active for the Surveyor Central repeater station. When using a Surveyor S12/S19 patient monitor, patient demographic information is communicated bidirectionally between the patient monitor and the Surveyor Central station — demographic information entered at the Surveyor Central station is sent to the patient monitor; demographic information entered at the patient monitor is sent to the Surveyor Central station. Patient data in the patients list can be added or edited allowing pre-admission by selecting New or Modify at the bottom of the display. The appropriate ID Format is also selected from the drop-down list in this window. When finished, select OK to save or Cancel to undo your changes. Review will open a multi-patient view of all of the current session events for all monitored patients. This allows you to filter, review, and edit all Events/Alarms. More detail will be explained later in this manual. Review is not available at the repeater station. Config will open a window that requires a password and will then present system configuration menus. The number of available monitoring days in the database memory and current date and time are displayed in the area to the far right. Feedback messages, when present, will appear in the lower left corner on the same status line. An informational message, such as a successful archive, will appear on a blue background. Error messages such as a print or archive failure will appear on a red background. Page | 31

Plethysmogram waveform
Signal Quality Indicator
Figure 9 - Detail view of a sub-screen showing telemetry from a Surveyor S4 with SpO2. The plethysmogram is derived from the SpO2 sensor placed on the patient, via the transmitting device. Its pulsatile characteristic reflects the flow of blood at the measurement site, but it is not a representation of arterial pressure. The plethysmogram is normalized so that its amplitude is continuously and automatically adjusted to fill the available display space. Consequently, the plethysmogram cannot be used to assess the strength of the signal; however, it is useful to visualize the impact of noise on the SpO2 signal. Within the SpO2 parameter block, the following items are displayed: functional oxygen saturation in units of % SpO2, pulse rate in units of beats/minute, and a Signal Quality Indicator (SQI) appearing as a colored square.

USING THE SYSTEM
Beginning a 12-lead ECG monitoring session
Correct electrode placement and skin preparation are important for acquiring a successful ECG and performing a reliable monitoring session. Low-amplitude signals may be the result of poor skin-to-electrode contact. To ensure electrode adherence, hair must be removed with a razor and the skin must be clean and dry. Gently abrade the skin where the gel will be in contact to ensure good ECG signal conduction. Avoid muscular and loose, flabby areas to minimize movement and muscular artifact. Good quality, long-term monitoring electrodes are recommended.

WARNING: Placement of the Left Leg (LL)* electrode in the original Mason-Likar position increases the similarity of the acquired ECG with a standard 12-lead ECG and is therefore recommended; however, clothing may interfere with this position and increase the amount of artifact. The modified position may decrease the sensitivity of inferior ECG leads and because axis shift with respect to the standard 12-lead ECG. Accurate skin preparation and suitable clothing are the most important factors in excessive artifact prevention. NOTE: The Right Leg (RL) electrode may be positioned in any location least subject to motion artifact according to clinician preference and specific test requirements.

USING THE SYSTEM To begin a 12-lead monitoring session: 1. Prep patient skin and attach monitoring electrodes and ECG cable to patient. 2. Ensure the Surveyor Central station is powered ON and displays patient monitoring slots. When a Surveyor S12/S19 patient monitor is used: o Power ON the patient monitor or resume monitoring from a Standbymode. o Ensure the Network icon on the S12/S19 main display shows communication to the Surveyor Central station. o Refer to the Surveyor S12/S19 patient monitor user manual (PN 9515-183-51-ENG). When a Surveyor S4 is used: o Apply the sensors to the patient and connect sensor cables to the S4. Refer to the S4 user manual (PN 9515-190-51-ENG) for specific instructions. o Secure the S4 to the patient’s body with the carrying pouch. o Turn the S4 ON by inserting batteries. o Ensure that the S4 establishes a connection to the Surveyor Central. o Check signal quality indicators on the S4, and re-prep electrode sites or reposition sensors as needed. o On the multi-patient display of Surveyor Central, locate the slot that matches the S4 and view the waveforms. NOTE: If you do not have a window set for the ambulatory transmitter, refer to the “System Configuration” section to setup receiver channels. Configurations for Surveyor S12/S19 and Surveyor S4 will be in place based on factory settings. 3. Click on window and the single-patient display will open with Patient Data tab active. Choose desired patient profile using the drop-down list box. NOTE: Creating and saving patient profiles will be explained in the Settings section of this user manual. 4. Click Start to start a new monitoring session. From this moment on, monitoring has started, data is stored, and the alarm system is activated. The system will ask you to select the best ECG detection leads. If you click No the system will use default lead settings (V1, V5 and II). When Yes is selected, real-time, 12-lead ECG traces will be displayed allowing you to change detection leads if necessary. Select Learn to make any changes. Refer to the “Traces” section for more detail about the Learn button. After reviewing or changing the 12-lead display settings, click on the Patient Data tab to return to the window that allows you to enter patient demographics.

When finished with all patient data operations, click Confirm in the lower portion of the display. A warning will ask if you are sure. Click Yes. NOTE: Confirmation of the patient data connects the stored data with patient demographics, and makes the data available for review. ID Format When ID Format option is present on your system, you can select from a drop-down list of user-created IDs. ID Formats in the list were imported by use of the configuration menu using the Management selection. ID formats are created in conjunction with Welch Allyn’s E-Scribe system with the custom ID feature. Patient data fields can be populated through the use of a bar code scanner. After scanning the bar code to populate the field, select Confirm. If the patient demographics were previously entered, all available data fields will be automatically filled. Note that the patient ID must be unique in order for this mechanism to work correctly. If there are more patients with the same patient ID registered, the data of the first found will be copied to these data fields. Patient data can be retrieved from the previously populated patients list by clicking Import and choosing from the list. Page | 39
USING THE SYSTEM WARNING: For patients with pacemakers, the Pacemaker Present checkbox field should be enabled and the minimum rate of the pacemaker selected from the list. Figure 16 - Multi-patient display sub-screen for a pacemaker patient. PM indicates that pacemaker detection is enabled. The Notes field can be used to store information about the patient that will be available in the patient data display for other clinicians. Text in this field does not appear on printouts. WARNING: Adjust the alarm thresholds to patient conditions after monitoring has started. Incorrect alarm threshold settings are a frequent cause of false alarms and lower the attention level to the genuinely important alarms. NOTE: Alarm settings cannot be changed in a Surveyor Central repeater station and are presented for informational purposes only. NOTE: The Surveyor S12/S19 patient monitors control the alarm activation, sound state and priority of each generated alarm, regardless of the limits and/or other settings configured on Surveyor Central (even if conflicting with Surveyor Central settings). The Surveyor Central station obtains these settings from the patient monitor. Reduced Lead-set Monitoring: Ambulatory Transmitter When using an ambulatory transmitter, patients can be monitored using a reduced lead set either by not connecting all the electrode wires or using a reduced lead-set cable. When a reduced lead set is used, select the 5 electrodes cable radio button in the patient data display. NOTE: When the selection in the window above is changed, ECG waveforms are flat-lined for 1 second, heart rate is reset, and any pending ECG alarms are cleared. NOTE: If you change from 10 to 5 electrodes, it is recommended to select the best leads for QRS-detection (see Learn menu in the Traces tab). 5-wire Monitoring Using R (RA), L (LA), F (LL), N (RL) and C1 (V1) electrodes will enable you to monitor leads I, II, III, aVR, aVL, aVF and V1. Select the 5 electrodes radio button. The C1 (V1) electrode can be placed on any desired position on the thorax and will display and print as V1. NOTE: When using an ambulatory transmitter, reduced lead monitoring or the selection of the 5 electrodes radio button will cause unused leads on the ECG printouts to be substituted by square waves. NOTE: When using an ambulatory transmitter, reduced lead monitoring or the selection of the 5 electrodes radio button cannot be used when 12-lead ECG interpretation is required. Page | 40
USING THE SYSTEM 3-wire Monitoring Using R (RA), L (LA), and F (LL), electrodes will enable you to monitor leads I, II, or III using the S4 mobile monitor or S12/S19 patient monitor when using it with a 3-wire cable. NOTE: When using the S12/S19 patient monitor, the lead displayed on the Central Station is always indicated as Lead II regardless of the setting on the S12/S19 patient monitor. Depending on the lead selected, the ECG waveform available will be displayed on the various panels as shown below with Lead II as an example here.

USING THE SYSTEM Protocol Manager When Protocol Manager is included with your system, you are able to select from a list of user-created protocols. Protocols in the list were imported by use of the configuration menu using the Management selection. The protocols have been created from a separate application and are programmed to initiate automatic events and printouts once the protocol has been started. Select the protocol you wish to use for the current patient from the drop-down list located in the Patient Data tab. Protocols are saved with each individual profile and will be automatically selected by the profile. You can change to a different protocol at any time while monitoring a patient. Note that protocols are not available for use with the S12/S19 patient monitors. Using a Protocol A protocol will initiate automatic events, reminders, and printouts once it is started. A new protocol can be selected when there is no other protocol in progress. There are two ways to start the protocol: 1. After the monitoring session has started, select the Patient Data tab and then select Start Protocol to begin. 2. Change the date and time values to the right of the Start Protocol button as desired and thenselect Schedule start. The protocol will automatically start at the scheduled time. Once the protocol has been started, Protocol buttons will appear as shown:
Figure 18 - Protocol manager command buttons.
Stop Protocol can be selected to stop the protocol at any time. Once this is done, a “Protocol Aborted” message will appear on the patient display.
The date and time values can be set to correct the protocol phase start. The protocol phase that is currently in progress will be reset to a 00:00 start time and will begin at the set time. Select Correct phase start after you have adjusted the date and time values.
Additionally, “Protocol Times” can be selected for display (chosen in the “Settings” tab under “Parameters”). The time on the left shows that the protocol phase has progressed for 42 seconds and the next protocol step (Prepare for baseline) will occur in 18 seconds as shown to the right. Protocol messages will appear in the alarm/event area of the display according to protocol definitions. Protocols can be defined with

USING THE SYSTEM Ending a Monitoring Session: Telemetry 1. On the multi-patient display, click on desired patient window. 2. Select Patient Data tab. 3. Click on the Stop button. 4. A warning will ask if you are sure. Click Yes. NOTE: If the monitoring slot has not been assigned to any patient, recorded data will be deleted!! 5. This patient data will appear in the Patients list with a “Stopped” monitoring status. Restarting a Monitoring Session: Telemetry 1. On the multi-patient display, click desired patient window and the patient data window will open with patient data grayed out. Select Same Patient to resume monitoring the same patient in the same monitoring window. 2. Selection of New Patient will remove the previous patient monitoring session from the patient slot allowing you to start monitoring a new patient. The previous patient’s monitoring session will be available for review and will be shown in the patients listing with a “Stopped” status. 3. Previous stopped patient monitoring sessions can be imported into any available monitoring window when starting a new monitoring session. This allows you to move the patient to a different ambulatory transmitter and display window as desired. This also allows you to combine multiple monitoring sessions for the same patient. NOTE: You can also start and stop monitoring sessions directly from the Surveyor S4 user interface. Discharge: Surveyor S12/S19 Patient Monitor The Discharge function at the Surveyor S12/S19 patient monitor is communicated to the Surveyor Central station. When the patient is discharged at the patient monitor, the monitoring slot at the Surveyor Central station closes and all patient information, trends, alarms, and other setting information are being cleared for that device. Standby: Surveyor S12/S19 Patient Monitor The Surveyor S12/S19 patient monitor has a Standby mode used to temporarily suspend patient monitoring (patient returning to same monitor) or permanently discharge the patient (patient not returning to monitor). This function is performed while standing at the patient’s bedside monitor. When the S12/S19 is placed in the Standby mode, the Surveyor Central station will discontinue monitoring. The Surveyor Central station displays a Standby message in that patient’s monitoring slot to note that monitoring is not active for that patient device. Once the patient monitor resumes monitoring, the Surveyor Central station will resume monitoring. Resume Monitoring: Surveyor S12/S19 Patient Monitor Once the Surveyor S12/S19 resumes monitoring after a Discharge or Standby mode, the Surveyor Central station will also resume monitoring. Page | 43
