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 on the user documentation CD or

www.welchallyn.com.) 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 staticsensitive 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 staticshielding bags before removing them from static-protected areas.

Page 11

Service manual Safety 7

• 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.

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 amber.

b. The Welch Allyn startup screen appears.

c. A beep sounds, followed by one chime.

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 personnel and

engineers in diagnosing the problem.

While in safe mode, the red LED bar and the piezo buzzer cycle on and off.

Troubleshooting

This section provides the following tables to help troubleshoot the device.

• Symptoms and solutions: These tables list symptoms you might observe, list

possible causes, and suggest actions that may eliminate the problem.

• Technical alarm messages: These tables list messages generated by the device

software when a problem is detected. The tables explain possible causes and suggest actions that can resolve the problem.

These tables can help you diagnose and fix a problem. They do not replace basic troubleshooting skills. You must still trace the source of the problem to the board or module level to decide the best course of action. Welch Allyn does not support component-level repair to the board or module. For available replacement parts, see “Field Replaceable Units.”

WARNING Do not perform troubleshooting on a device that is emitting smoke or exhibits other signs of excessive overheating. Disconnect the device from AC power and call Welch Allyn Technical Support immediately.

CAUTION Replace parts, components, or accessories only with parts supplied or approved by Welch Allyn. The use of any other parts can lead to inferior device performance and will void the product warranty.
