In this unit, about 10 seconds after power is supplied (8.4V) to the
battery terminal using the service power cord (J-6082-223-A), the
power is shut off so that the unit cannot operate.
This following method is available to prevent this.

Use the DC IN terminal. (Use the AC power adaptor.)

When problems occur while the unit is operating, the self-diagnosis
function starts working, and displays on the viewfinder or LCD 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.

Note: The “self-diagnosis display” data will be backed up by the built-in rechargeable lithium battery (CF-1000 block/CF-077

board BT101). When the cabinet (R) assembly is disconnected, the “self-diagnosis display” data will be lost by initialization.

When problems occur while the unit is operating, the counter of the
viewfinder or LCD 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 “VTR or PLAYER”, 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.
