Safety

3
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.
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.

Safety Welch Allyn Connex® Vital Signs Monitor 6000 Series™

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 device’s directions for use). 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 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.

Battery performance

About the battery

The device uses a rechargeable lithium ion smart battery. Internal circuitry enables the battery to report its condition to the device. 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. Battery information may be collected using the service tool.
New batteries are shipped from the manufacturer with a 30 percent charge to extend shelf life. When installing a new battery in the device, you must plug the device into AC power to wake up the battery. If the AC power is not applied to the device, the new battery will appear discharged.
The Device Status area displays a low-battery status message when 30 minutes of power remain and again when 5 minutes remain.
You can expect new, fully charged batteries to have enough power for the following:
Six-cell batteries provide approximately 26 patient exams.
Nine-cell batteries provide approximately 47 patient exams.
Note A patient exam includes NIBP, temperature, and SpO2 measurements at the rate of
The number of exams per charge decrease with the battery age.
Depending on the age of the battery, a 6-cell battery takes 3 hours and a 9-cell battery takes 4 hours to fully charge at room temperature.
Both batteries have a lifetime of 300 charge cycles or more, where a charge cycle is equal to fully charged to discharged to fully charged at room temperature.
Battery charging is provided by the device’s internal power supply.
For a complete list of battery specifications, see the device’s directions for use.

Best practices

The following practices help to extend the life of the battery and the device.
Remove the battery when storing the device.
Replace batteries that trigger a low battery status message when fully charged.
Do not use damaged or leaking batteries.
Store batteries with a 30 to 50 percent charge.
Store batteries within the temperature range indicated for each period:
one patient every 10 minutes with a 2 minute display timeout setting with a new battery, conducted at room temperature (72.5 °F ±4.5 °F; 22.5 °C ±2.5 °C).
WARNING Safety risk. When handling and storing Lithium batteries: Avoid mechanical or electrical abuse. Batteries may explode or cause burns, if disassembled, crushed or exposed to fire or high temperatures. Do not short or install with incorrect polarity.
For storage less than 30 days: Maintain temperature at –4 °F and 122 °F (–20 °C and 50 °C).
For storage between 30 days and 90 days: Maintain temperature at –4 °F and 104 °F (–20 °C and 40 °C).
12
Overview Welch Allyn Connex® Vital Signs Monitor 6000 Series™
For storage more than 90 days up to 2 years: Maintain temperature at –4 °F and 95 °F (–20 °C and 35 °C).
Recycle batteries where ever possible. In the United States call 1-800-8-BATTERY for information about recycling your Lithium Ion battery or go to the RBRC website at

Power-up sequence

The system performs a power-on self test (POST) each time the device is powered on. During power up, the system performs a comprehensive self test of the software. If software testing is successful, the system then tests internal hardware. If all tests are successful, the system completes power up and the Home screen appears.
To perform the POST:
1. Disconnect any patient cables connected to the system.
2. Insert a fully charged battery into the system.
3. Upon each power up, confirm the following:
a. The light bar flashes red then amber.
b. The Welch Allyn startup screen appears.
c. A beep sounds, followed by two chimes.
23
Note If no chimes sound, replace the speaker as specified in
“Remove the speaker.”
d. The product line logo appears at the bottom of the screen.
e. If a printer is installed, the paper advances slightly.
f. The Home screen appears.
WARNING Equipment failure risk. The system includes a fan that circulates air through the device. If the fan does not run when you power up the device, remove it from use and inform qualified service personnel immediately. Do not use the system until the problem is corrected.
If the internal self-check is successful, the system shows its normal functions with all values blank and the system is ready for operation. If the self-check fails, an error message appears in the system status area at the top of the screen. If a fault that could adversely affect the product is detected, the system enters a safe mode and stops monitoring patients. The system remains in safe mode until it is turned off by pressing the Power button or until it shuts down automatically after a period of inactivity.
If a system error is detected, the system becomes inactive until you press or until the system
shuts down automatically. The system displays a system fault message that contains a wrench icon( ) and a system fault code to aid service and engineers in diagnosing the problem.
While in safe mode, the red LED bar and the piezo buzzer cycle on and off.
