SERVICING NOTICES ON CHECKING
1. KEEP THE NOTICES
3. PUT PARTS AND WIRES IN THE ORIGINAL
POSITION AFTER ASSEMBLING OR WIRING
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.
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.
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.
4. PERFORM A SAFETY CHECK AFTER
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
Press the Power key and 1 key on the remote control
simultaneously for more than 2 seconds.
Custom code 2 : Press the Power key and 2 key on the remote control
simultaneously for more than 2 seconds.
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.

CLEANING
NOTE
2. TAPE RUNNING SYSTEM
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.
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.)
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.)
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.

1-2: CONFIRMATION AND ADJUSTMENT OF TENSION
POST POSITION
1. CONFIRMATION AND ADJUSTMENT
Read the following NOTES before starting work.
1. Set to the PLAY mode.
2. Adjust the Tension Adjust until the length from the edge
of the Tension Arm to the standard line of the Main
Chassis is 0.5 ± 0.25mm.
After this adjustment, confirm that the cut position is
located in "A" area as shown in Fig. 1-2-B. If it is
located in "B" area, adjust again.
3. While turning the S Reel clockwise, confirm that the
edge of the Tension Arm is located in the position
described above.
• 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.
1-1: CONFIRMATION AND ADJUSTMENT OF REEL
DISK HEIGHT
Standard line of Main Chassis
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. 11-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.

and CH-2 to TP4001 (SW Pulse).
3. Press and hold the TRACKING-AUTO button on the
remote control more than 2 seconds to set tracking to
center.
4. Trigger with SW Pulse and observe the envelope. (Refer
to Fig. 2-1-A)
5. When observing the envelope, adjust the Adjusting Driver
(JG005) slightly until the envelope will be flat.
Even if you press the Tracking Button, adjust so that
flatness is not moved so much.
6. Adjust so that the A : B ratio is better than 3 : 2 as shown
in Fig. 2-1-B, even if you press the Tracking Button to
move the envelope (The envelope waveform will begin to
decrease when you press the Tracking Button).
7. Adjust the PG shifter during playback.
(Refer to the ELECTRICAL ADJUSTMENTS)
1-5: CONFIRMATION OF REEL BRAKE TORQUE
(S Reel Brake) (Refer to Fig. 1-4)
1. Set to the STOP mode.
2. Move the Idler Ass'y from the S Reel.
3. Install the Torque Gauge (JG002F) and Adapter
(JG002B) on the S Reel. Turn the Torque Gauge
(JG002F) clockwise.
4. Then, confirm that it indicates 70~100gf•cm.
(T Reel Brake) (Refer to Fig. 1-4)
1. Set to the STOP mode.
2. Move the Idler Ass'y from the T Reel Ass'y.
3. Install the Torque Gauge (JG002E) and Adapter
(JG002B) on the T reel. Turn the Torque Gauge
(JG002E) counterclockwise.
4. Then, confirm that it indicates 35~60gf•cm.
