SERVICING NOTICES ON CHECKING

1. KEEP THE NOTICES

As for the places which need special attentions, they are
indicated with the labels or seals on the cabinet, chassis
and parts. Make sure to keep the indications and notices
in the operation manual.

2. USE THE DESIGNATED PARTS

The parts in this equipment have the specific
characters of incombustibility and withstand voltage for
safety. Therefore, the part which is replaced should be
used the part which has the same character.
Especially as to the important parts for safety which is
indicated in the circuit diagram or the table of parts as
a mark, the designated parts must be used.

3. PUT PARTS AND WIRES IN THE ORIGINAL
POSITION AFTER ASSEMBLING OR WIRING

There are parts which use the insulation material such
as a tube or tape for safety, or which are assembled in
the condition that these do not contact with the printed
board. The inside wiring is designed not to get closer to
the pyrogenic parts and high voltage parts. Therefore,
put these parts in the original positions.

PERFORM A SAFETY CHECK AFTER

4.

SERVICING

Confirm that the screws, parts and wiring which were
removed in order to service are put in the original
positions, or whether there are the portions which are
deteriorated around the serviced places serviced or not.
Check the insulation between the antenna terminal or
external metal and the AC cord plug blades. And be sure
the safety of that.

IMPORTANT NOTICE

The remote control for this model can be selected the Custom code 1 and Custom code 2.

• How to selection;
Custom code 1 : P

Custom code 2 :

The Custom code 1 is only available for the VCR unit but the Custom code 2.
When selected the Custom code 2 by mistake, just remove the batteries from the remote
control for the moment or select the Custom code 1 as described above.

PREVENTIVE CHECKS AND SERVICE INTERVALS

CLEANING

NOTE

After cleaning the heads with isopropyl alcohol, do not
run a tape until the heads dry completely. If the heads
are not completely dry and alcohol gets on the tape,
damage may occur.

1. AUDIO CONTROL HEAD

Wrap a piece of chamois around your finger. Dip it in
isopropyl alcohol and clean the audio control head by
wiping it horizontally. Clean the full erase head in the
same manner. (Refer to the figure below.)

2. TAPE RUNNING SYSTEM

When cleaning the tape transport system, use the
gauze moistened with isopropyl alcohol.

3. CYLINDER

Wrap a piece of chamois around your finger. Dip it in
isopropyl alcohol. Hold it to the cylinder head softly.
Turn the cylinder head counterclockwise to clean it (in
the direction of the arrow). (Refer to the figure below.)

NOTE

Do not exert force against the cylinder head. Do not move
the chamois upward or downward on the head.
Use the chamois one by one.

MECHANICAL ADJUSTMENTS

1. CONFIRMATION AND ADJUSTMENT

Read the following NOTES before starting work.

••Place an object which weighs between 450g~500g on
the Cassette Tape to keep it steady when you want to
make the tape run without the Cassette Holder. (Do not
place an object which weighs over 500g.)
When you activate the deck without the Cassette
Holder, short circuit between TP1001 and TP1002.

(Refer to ELECTRICAL ADJUSTMENT PARTS
LOCATION GUIDE) In this condition the BOT/EOT/Reel

Sensor will not function.

CONFIRMATION AND ADJUSTMENT OF REEL

1-1:

DISK HEIGHT

1.

Turn on the power and set to the STOP mode.

2.

Set the master plane (JG022) and reel disk height
adjustment jig (JG024A) on the mechanism framework,
taking care not to scratch the drum, as shown in Fig. 1-
1-A.

3.

Confirm that "A" of the reel disk is lower than "B" of the
reel disk height adjustment jig (JG024A) , and is higher
than "C". If it is not enough height, adjust to 10(+0.2, -0)
mm with the height adjustment washer.

4.

Adjust the other reel in the same way.
