When problems occur while the unit is operating, the self-diagnosis
function starts working, and displays on the LCD screen or monitor
TV (Note) 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.

The “self-diagnosis display” data will be backed up by the coin-type lithium battery of FP-571 flexible board. When this coin-type lithium battery
is removed, the “self-diagnosis display” data will be lost by initialization.

When problems occur while the unit is operating, the counter of the
viewfinder 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.

Set the DISPLAY in the menu system to V-OUT/LCD only for the
model with LCD screen, and press the DISPLAY button.

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

While pressing the “STOP” key, set the POWER switch from OFF to ON, and continue pressing the “STOP” key for 10 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.
