PROTECTION SHUTDOWN

Self Diagnosis
Supported model
The models in this manual contain a self-diagnostic function. If an
error occurs, the standby LED will automatically begin to flash. The
number of times the LED flashes translates to a probable source of
the problem.
A history of the errors is stored on the Self Check diagnostic page
as shown in "Figure 4-3. Sample Self Check Diagnosis Page" on
page 37. This page can be used to review the failure occurrence
data stored in memory to reveal past problems and how often these
problems occured. If there is more than one error, the standby LED
will identify the first of the problem areas. If the Self Check screen
displays a 0, no error has occurred.
