Safety All users of the monitor must read and understand all safety information presented in this manual before using or repairing the monitor. United States federal law restricts this device to sale, distribution, or use by or on the order of a licensed medical practitioner.
Warnings and cautions WARNING Safety risk. Make frequent electrical and visual checks on cables, sensors, and electrode wires. All cables, sensors, and electrode wires must be inspected and properly maintained and in proper working order to allow the equipment to function properly and to protect patients. WARNING Safety risk. Place the monitor and accessories in locations where they cannot harm the patient should they fall from a shelf or mount. WARNING Fire and explosion hazard. Do not operate the monitor in the presence of a flammable anesthetic mixture with air, oxygen, or nitrous oxide; in oxygenenriched environments; or in any other potentially explosive environment. WARNING Inaccurate measurement risk. Dust and particle ingress can affect the accuracy of blood pressure measurements. Use the monitor in clean environments to ensure measurement accuracy. If you notice dust or lint build-up on the monitor’s vent openings, have the monitor inspected and cleaned by a qualified service technician. WARNING Defective batteries can damage the monitor. If the battery shows any signs of damage or cracking, it must be replaced immediately and only with a battery approved by Welch Allyn. CAUTION Before disassembling the device or installing options, disconnect the patient from the monitor, power down the device, and disconnect the AC power cord and any attached accessories (for example, SpO2 sensors, blood pressure hoses and cuffs, and temperature probes) from the device. CAUTION To ensure that the monitor meets its performance specifications, store and use the monitor in an environment that maintains the specified temperature and humidity ranges.
6 Safety

CAUTION Do not connect more than one patient to a monitor or connect more than one monitor to a patient. CAUTION Do not operate the monitor in the presence of magnetic resonance imaging (MRI) or hyperbaric chambers.
General safety considerations •
If the monitor detects an unrecoverable problem, it displays an error message. For more information, see “Troubleshooting.”
•
To ensure patient safety, use only accessories recommended or supplied by Welch Allyn. (See the accessories list in the Appendix of the Instructions for use or https://direct.hill-rom.com/ hillromUS/en.) Always use accessories according to your facility’s standards and according to the manufacturer’s recommendations and instructions. Always follow the manufacturer’s directions for use.
•
Welch Allyn recommends that only Welch Allyn service personnel or an authorized repair center perform warranty service. Performing unauthorized service on a device that is within warranty may void the warranty.
Electrostatic discharge (ESD)
CAUTION Electrostatic discharge (ESD) can damage or destroy electronic components. Handle static-sensitive components only at static-safe workstation. CAUTION Assume that all electrical and electronic components of the monitor are static-sensitive. Electrostatic discharge is a sudden current flowing from a charged object to another object or to ground. Electrostatic charges can accumulate on common items such as foam drinking cups, cellophane tape, synthetic clothing, untreated foam packaging material, and untreated plastic bags and work folders, to name only a few. Electronic components and assemblies, if not properly protected against ESD, can be permanently damaged or destroyed when near or in contact with electrostatically charged objects. When you handle components or assemblies that are not in protective bags and you are not sure whether they are static-sensitive, assume that they are static-sensitive and handle them accordingly. •
Perform all service procedures in a static-protected environment. Always use techniques and equipment designed to protect personnel and equipment from electrostatic discharge.
•
Remove static-sensitive components and assemblies from their static-shielding bags only at static-safe workstations-a properly grounded table and grounded floor mat-and only when
Safety 7
Service manual
you are wearing a grounded wrist strap (with a resistor of at least 1 megohm in series) or other grounding device. •
Use only grounded tools when inserting, adjusting, or removing static-sensitive components and assemblies.
•
Remove or insert static-sensitive components and assemblies only with monitor power turned off.
•
Insert and seal static-sensitive components and assemblies into their original static-shielding bags before removing them from static-protected areas.
•
Always test your ground strap, bench mat, conductive work surface, and ground cord before removing components and assemblies from their protective bags and before beginning any disassembly or assembly procedures.

Overview
Welch Allyn® Connex® Spot Monitor
Some of these features are enabled for any user (Standard unlicensed edition). Others require special user account privileges or a Welch Allyn service contract (Gold edition). If you require goldlevel support for a Welch Allyn product, please contact Welch Allyn technical support.
Battery performance About the batteries The device uses a rechargeable, 2-cell, Lithium-ion smart battery supplemented by an optional, rechargeable, 9-cell Lithium-ion battery in the Accessory Power Management (APM) work surface. Internal circuitry enables the batteries to report their condition to the device and the APM work surface. The device displays the battery status via the LED power indicator, icons on the screen, and status messages appearing in the Device Status area of the display. The APM battery indicates the percent of total charge to user on the front of the work surface as follows: Number of LEDs
Percent of total charge
1
0 – 19
2
20 – 39
3
40 – 59
4
60 – 79
5
80 – 95
6
96 – 100
The battery status indicator on the device displays the remaining total charge of both batteries combined if the configuration has both an internal battery and an extended battery in the APM. Battery information may be collected using the service tool. New batteries are shipped from the manufacturer with a 40 percent charge to extend shelf life. After installing a new battery in the device, you must plug the device into AC power to wake up the battery. If AC power is not applied to the device, the new battery appears discharged. The Device Status area displays a low-battery status message when 30 minutes of power remain and again when 5 minutes remain. The 30-minute message is a very low priority technical alarm. The alarm message appears on a cyan background in the Device Status area. This alarm is dismissable by the user, and all functions of the device remain available. The 5-minute message is a high priority technical alarm that appears on a red background in the Device Status area, is not dismissable, and prevents acquiring vitals measurements or performing any other function until the device is plugged in to AC power. If AC power is not applied to the device after it triggers the high priority technical alarm, the device will shut down at or close to 0 minutes of remaining battery charge. Battery charging is provided by the device’s power supply. The power reserve threshold is determined by the device's software. For a complete list of battery specifications, see the device’s Instructions for use.
