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.
