Error Log
For troubleshooting intermittent problems, the monitor maintains an error log for both recoverable and non-
recoverable errors in its battery-backed, non-volatile memory. All diagnostics failures are logged in the error
log.
Most errors relate to the CPU PCBA, but some errors may be caused by the parameter module or software
errors. For example, a particular sequence of key strokes that always produces the same error code could be
a software problem.
Displaying the Error Log
Before using the Error Log, ensure that all other procedures have been followed, including elimination of
operator errors, testing of voltages, correction of display faults, diagnostic testing, cabling/connector repairs,
software compatibility, etc.
From the Boot menu (refer to Boot Menu on page 5-3), touch E to access the Error Log Functions menu,
then d to view the Error Log.
