SERVICE NOTE
1.
POWER SUPPLY DURING REPAIRS
In this unit, about 10 seconds after power is supplied (8.4 V) to the
battery terminal using the service power cord (J-6082-223-A), 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.
Method 1.
Connect the servicing remote commander RM-95 (J-6082-053-B)
to the LANC jack, and set the remote commander switch to the
“ADJ” side.
Method 2.
Press the battery switch of the battery terminal using adhesive tape,
etc.
Method 3.
Use the DC IN terminal. (Use the AC power adaptor.)
2.
TO TAKE OUT A CASSETTE WHEN NOT EJECT (FORCE EJECT)
1
Refer to 2-3 to remove the front panel assembly.
2
Refer to 2-5 to remove the cabinet (R) assembly.
3
Refer to 2-7 to remove the cabinet (L) assembly.
4
Refer to 2-8 to remove the battery panel assembly.
5
Disconnect CN4401 of VC-235 board.
6
Add +5 V from the DC POWER SUPPLY and unload with a
pressing the cassette lid.

NOTE FOR REPAIR
Make sure that the flat cable and flexible board are not cracked of
bent at the terminal.
Do not insert the cable insufficiently nor crookedly.
When remove a connector, don’t pull at wire of connector.
It is possible that a wire is snapped.
Cut and remove the part of gilt 
which comes off at the point.
(Be careful or some pieces of 
gilt may be left inside)
When installing a connector, don’t press down at wire of connector.
It is possible that a wire is snapped.

LCD  TYPE  CHECK
By measuring the resistor value between Pin 6 of CN5502 and
Pin 0 of CN5502 on PD-118 board, the type of LCD can be dis-
criminated.
Note:
About PD-118 board and LCD module, discriminate LCD
type on the machine, and replace the same type.
