3. Executing Self Diag
Self Diag enables the user to execute self-diagnosis of the equipment. When Self Diag is run, the result of
self-diagnosis appears regardless of whether the result is good or bad.
The self-diagnosis can be executed only under the following conditions. When executing the self-diagno-
sis, change to the following conditions with the SHUTTER switch and the SETUP menu.
. SHUTTER switch: Off
. EX Slow Shutter: Off

(1) Self-diagnostic items
The following two types of self-diagnosis are provided.
. Type1: Simple self-diagnosis
. Use to execute a simple version of the self-diagnosis. This finishes in a short time.
. Type2: Complete self-diagnosis
. This executes all items included in the Self Diag. Since complete self-diagnosis involves a memory
test and a complicated device test, this requires time to be completed. In addition, since the system
cannot be returned to normal operations after the self-diagnosis, the power must be turned off and on
again.

The self-diagnostic items range from Item1 to Item13.
