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

[3] : Occurred third time

[5] : Occurred fifth time

[2] : Occurred second time

[4] : Occurred fourth time

[6] : Occurred the last time

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

Note: The “self-diagnosis display” data will be backed up by the lithium battery (CONTROL SWITCH BLOCK (CF-3000):

BT001). When removing the cabinet (R) (removing the VC-305 board CN1007), the “self-diagnosis display” data will
be lost by initialization.
