Note:
Provides information to further assist in the use of the device.
Warning(s) •
This manual gives important information about the use and safety of this device. Deviating from operating procedures, misuse or misapplication of the device, or ignoring specifications and recommendations could result in increased risk of harm to users, patients and bystanders, or damage to the device.
•
Device transmits data reflecting a patient’s physiological condition to a properly equipped receiving device 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.
•
Users are expected to be licensed clinical professionals knowledgeable about medical procedures and patient care, and adequately trained in the use of this device. Before attempting to use this device 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 device. Contact Mortara service for additional training options.
•
To maintain designed operator and patient safety, peripheral equipment and accessories used that can come in direct patient contact must be in compliance with UL 60601-1, IEC 60601-1, and IEC 60601-2-25. Only use parts and accessories supplied with the device and available through Mortara Instrument, Inc.
•
Patient cables intended for use with the device include series resistance (9 Kohm minimum) in each lead for defibrillation protection. Patient cables should be checked for cracks or breakage prior to use.
•
Conductive parts of the patient cable, electrodes, and associated connections of type CF applied parts, including the neutral conductor of the patient cable and electrodes, should not come into contact with other conductive parts including earth ground.
•
ECG electrodes could cause skin irritation; patients should be examined for signs of irritation or inflammation.
•
To avoid the possibility of serious injury or death during patient defibrillation, do not come into contact with device or patient cables. Additionally, proper placement of defibrillator paddles in relation to the electrodes is required to minimize harm to the patient.
•
Defibrillation protection is guaranteed only if the original patient cable is used. Any modification of this device may alter defibrillator protection.
•
To avoid potential for spread of disease or infection, single-use disposable components (e.g., electrodes) must not be reused. To maintain safety and effectiveness, electrodes must not be used beyond their expiration date.
•
This device was designed to use the electrodes specified in this manual. Proper clinical procedure must be employed to prep the electrode sites and to monitor the patient for excessive skin irritation, inflammation, or

USER SAFETY INFORMATION
other adverse reactions. Electrodes are intended for short-term use and should be removed from the patient promptly following testing. ●
FCC Warning (Part 15.21): Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the device.
•
A possible explosion hazard exists. Do not use the device in the presence of a flammable anesthetic mixture.
•
The device has not been designed for use with high-frequency (HF) surgical equipment and does not provide a protective means against hazards to the patient.
•
The quality of the signal produced by the device may be adversely affected by the use of other medical equipment, including but not limited to defibrillators and ultrasound machines.
•
There is no known safety hazard if other equipment, such as pacemakers or other stimulators, is used simultaneously with the device; however, disturbance to the signal may occur.
•
Operations may be affected in the presence of strong electromagnetic sources such as electrosurgery equipment.
•
The battery operated device transmits data reflecting a patient’s physiological condition to a receiving device. During operation failure, data transmission and LCD information will cease to occur. In mission critical conditions, it is advisable to have a backup device available.
•
Use only recommended alkaline battery cells. Use of other cells may present a risk of fire or explosion.
•
Low battery warning function is designed for alkaline battery cells only. Use of other cells may result in failure of the low battery warning possibly resulting in a malfunction of the device.
•
Do not attempt to clean the device or patient cables by submersing into a liquid, autoclaving, or steam cleaning as this may damage equipment or reduce its usable life. Use of unspecified cleaning/disinfecting agents, failure to follow recommended procedures, or contact with unspecified materials could result in increased risk of harm to users, patients and bystanders, or damage to the device. Do not sterilize the device or patient cables with Ethylene Oxide (EtO) gas.
•
The ELI 350 does not automatically switch between the device and a direct patient cable. Clinician must choose the desired cable in the Settings menu before ECG acquisition. Switching between a direct patient cable and the device does not require the device to be re-paired with the ELI 350 unless a different device is to be used. The selected patient cable will display continuously under the Settings menu button.
•
The minimum amplitude of the patient physiological signal that the ME equipment or system accepts is 30 μV. Operation of the ME equipment or ME system below this amplitude may cause inaccurate results.

ELECTROMAGNETIC COMPATIBILITY (EMC) Electromagnetic compatibility with surrounding devices should be assessed when using the device. An electronic device can either generate or receive electromagnetic interference. Testing for electromagnetic compatibility (EMC) has been performed on the device 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). The device should not be used adjacent to, or stacked on top of other equipment. If the device must be used adjacent to or stacked on top of other equipment, verify that the device 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 appropriate EMC table for recommended separation distances between the radio equipment and the device. The use of accessories, transducers, and cables other than those specified by Mortara Instrument may result in increased emissions or decreased immunity of the equipment.

Where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer and d is the recommended separation distance in meters (m). Field strengths from fixed RF transmitters, as determined by an electromagnetic site surveya, should be less than the compliance level in each frequency rangeb. Interference may occur in the vicinity of equipment marked with the following symbol:
NOTE 1: At 800 MHz, the separation distance for the higher frequency range applies. NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by the absorption and reflection from structures, objects, and people. a. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radios, AM and FM radio broadcast, and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the equipment is used exceeds the applicable RF compliance level above, the equipment should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the equipment. b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [3] V/m.
