When problems occur while the unit is operating, the self-diagnosis
function starts working, and displays on the viewfinder or Display
window what to do. This function consists of two display; self-
diagnosis display and service mode display.
Details of the self-diagnosis functions are provided in the Instruction
manual.

When problems occur while the unit is operating, the counter of the
viewfinder or Display window shows a 4-digit display consisting
of an alphabet and numbers, which blinks at 3.2 Hz. This 5-character
display indicates the “repaired by:”, “block” in which the problem
occurred, and “detailed code” of the problem.

The service mode display shows up to six self-diagnosis codes shown in the past.

While pressing the “STOP” key, set the switch from OFF to “VCR”, and continue pressing the “STOP” key for 5 seconds continuously. The
service mode will be displayed, and the counter will show the backup No. and the 5-character self-diagnosis codes.

By rotating the control dial, past self-diagnosis codes will be shown in order. The backup No. in the [] indicates the order in which the
problem occurred. (If the number of problems which occurred is less than 6, only the number of problems which occurred will be shown.)
[1] : Occurred first time

[4] : Occurred fourth time

[2] : Occurred second time

[5] : Occurred fifth time

[3] : Occurred third time

[6] : Occurred the last time

Turning OFF the power supply will end the service mode display.

After repair, be sure to perform “1-7. PROCESS AFTER FIXING FLASH ERROR”.

1-6E

When “FLASH error” (Self-diagnosis Code E:91:**) occurs, to prevent any abnormal situation caused by high voltage, setting of the flash is
changed automatically to disabling charge and flash setting.
After fixing, this setting needs to be deactivated. Connect the adjustment remote commander and perform the following process.
