Loading motor

DC power supply

(+4.5Vdc)

VC-280 board

CN1010

In this unit, about 10 seconds after power is supplied to the battery terminal using the regulated power supply (8.4V), 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.

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

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

1

Refer to 2-3. to remove the front panel assembly.

2

Refer to 2-5. to remove the top cabinet assembly.

3

Refer to 2-6. to remove the cabinet (R) assembly.

4

Refer to 2-7. to remove the battery panel section.

5

Remove the EVF block.

6

Open the VA-117 board.

7

Disconnect CN1010 (27P, 0.3mm) of VC-280 board.

8

Open the cassette lid.

9

Supply +4.5V from the DC power supply to the loading motor and unload with a pressing the cassette compartment.
