In this unit, about 10 seconds after power is supplied (8.4V) to the battery terminal using the service power code (J-6082-223-A), the power
is shut off so that the unit cannot operate.
These following two methods are available to prevent this. Take note of which to use during repairs.

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

Connect the adjustment remote commander RM-95 (J-6082-053-B) to the LANC jack, and set the HOLD switch to the “ADJ” side.

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.

Note: The “self-diagnosis display” data will be backed up by the coin-type lithium battery (CF-2500 block BT101). When the

CF-2500 block 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 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.
