When problems occur while the unit is operating, the self-diagnosis
function starts working, and displays on the viewfinder 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 LI-64 board. When this coin-type lithium battery is disconnected,
the self-diagnosis 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.

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 “CAMERA” or “VTR or PLAYER”, 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.
