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.

PREVENTIVE CHECKS AND SERVICE INTERVALS 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.

MECHANICAL ADJUSTMENTS 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 edge of the Tension Arm is positioning within 0.5mm range from the standard line center of Main Chassis. 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.

2. CONFIRMATION AND ADJUSTMENT OF TAPE RUNNING MECHANISM
NOTE
Tape Running Mechanism is adjusted precisely at the factory. Adjustment is not necessary as usual. When you replace the parts of the tape running mechanism because of long term usage or failure, the confirmation and adjustment are necessary.
Install the Torque Gauge on the reel disk firmly. Press the REW button to turn the reel disk.
2-1: GUIDE ROLLER 1. Playback the VHS Alignment Tape (JG001C or JG001E). (Refer to SERVICING FIXTURE AND TOOLS) 2. Connect CH-1 of the oscilloscope to TP4002 (Envelope) 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. Torque Gauge/Adapter (JG002F/JG002B)
