Troubleshooting
This section lists symptoms that you might observe, possible causes, and suggested actions that
might eliminate 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.”
The Welch Allyn Service Tool enables you to access the error log for this device. The error log
contains diagnostic information in the form of text string errors. You can find descriptions of the
text string errors in the service tool Help files, along with potential corrective actions that do not
require device disassembly. If these corrective actions do not solve the problem, reference the
observed behavior in the tables below.
NOTE
Numeric error codes displayed alongside the text string errors are for
engineering evaluation purposes. These codes are not intended for diagnostic use.
