In this unit, about 10 seconds after power is supplied to the battery
terminal using the regulated power supply (8.4 V), the power is
shut off so that the unit cannot operate.
This following two methods are available to prevent this. Take note
of which to use during repairs.

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

Use the DC IN terminal. (Use the AC power adaptor (AC-L10, AC-
VQ800 etc. ))

1 Refer to 2-2. to remove the front panel assembly.
2 Refer to 2-3. to remove the cabinet (R) assembly.
3 Refer to 2-3. to remove the battery panel assembly.
4 Refer to 2-4. to remove the viewfinder assembly.
5 Refer to 2-6. to remove DD-123 board.
6 Refer to 2-6. to remove VC-217 board.
7 Refer to 2-7. to remove the mechanism deck.
8 Add +4.5 V from the DC POWER SUPPLY and unload with a

pressing the cassette compartment.

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

The “self-diagnosis display” data will be backed up by the coin-type lithium battery of CK-84 board BT8600. When this coin-type lithium battery
is removed, the “self-diagnosis display” data will be lost by initialization.

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.

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.
