SELF-DIAGNOSIS FUNCTION
1.SELF-DIAGNOSIS FUNCTION
When problems occur while the unit is operating, the self-diagnosis
function starts working, and displays on the viewf inder, LCD screen
or LCD 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.

2.SELF-DIAGNOSIS DISPLAY
When problems occur while the unit is operating, the counter of the
viewfinder, LCD screen or LCD window consists of an alphabet
and 4-digit 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.

Detailed Code
Refer to page 8.
Self-diagnosis Code Table.
3.SERVICE MODE DISPLAY
The service mode display shows up to six self-diagnosis codes shown in the past.
3-1.Display Method
While pressing the “STOP” key, set the switch from OFF to “VCR 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.)

Turning OFF the power supply will end the service mode display.
Note: The “self-diagnosis display” data will be backed up by the coin-type lithium battery of CK-093 board BT250. When CK-093 board is removed,
the “self-diagnosis display” data will be lost by initialization.

When replacing this board, remove the CCD imager from the
old one and mount it onto the new one.
• If the CCD imager has been replaced, carry out all the adjustments for the camera section.
• As the CCD imager may be damaged by static electricity from
its structure, handle it carefully like for the MOS IC.
In addition, ensure that the receiver is not covered with dusts
nor exposed to strong light.
