SERVICE NOTE
1. POWER SUPPLY DURING REPAIRS
In this unit, about 5 seconds after power is supplied (8.4V) 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
Battery sig terminal
of which to use during repairs.
Battery terminal `
Method 1.
Connect the servicing remote commander RM-95 (J-6082-053-B)
Battery switch
to the LANC jack, and set the remote commander switch to the
"ADJ" side.
Method 2. Battery terminal '
Press the following battery switch using adhesive tape, etc.
2. HOW TO TAKE A CASSETTE OUT WHEN THE MAIN POWER
CANNOT BE TURNED ON (FORCED EJECTED)
Procedure:
1. Remove the cassette lid referring to the section "2. DISASSEMBLY, 2-1".
2. Remove the operation switch block (FK-71 board) referring to the section "2. DISASSEMBLY, 2-5".
3. Remove the CB-61 board referring to section "2. DISASSEMBLY, 2-4", and remove the FP-586 flexible board from CN3140 (4P) on
the RJ-77 board.
4. Apply +4.5 V from the regulated power supply to the loading motor terminal as shown below and remove the cassette.
CAUTION: Be careful not contact with the lid frame assembly when applying +4.5 V.

If the CAUTION lamp flashes, but no indicators appear on the LCD screen or on the monitor TV screen, it means that an error occurs either
in the fan motor or in the fan motor drive circuit. Refer to the schematic diagram on page 4-43 for repair.
