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.
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.
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.

Notes
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.

Confirm that the meter indicates 20 ± 2gf in the beginning of playback. · USING A CASSETTE TYPE TORQUE TAPE (JG100A) 1. After confirmation and adjustment of Tension Post position (Refer to item 1-2), load the cassette type torque tape (JG100A) and set to the PLAY mode. 2. Confirm that the right meter of the torque tape indicates 60~110gf·cm during playback in SP mode. 3. Confirm that the left meter of the torque tape indicates 25~40gf·cm during playback in SP mode.

(Refer to Fig.1-4) 3. Then, confirm that it indicates 120~180gf·cm. NOTE Install the Torque Gauge on the reel disk firmly. Press the REW button to turn the reel disk. 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 60~100gf·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. 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 45~70gf·cm.
Torque Gauge/Adapter (JG002F/JG002B)
2. CONFIRMATION AND ADJUSTMENT OF TAPE RUNNING MECHANISM
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. 2-1: GUIDE ROLLER 1. Playback the VHS Alignment Tape (JG001 or JG001B). (Refer to SERVICING FIXTURE AND TOOLS) 2. Connect CH-1 of the oscilloscope to TP4001 (Envelope) and CH-2 to TP1002 (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) NOTE After adjustment, confirm and adjust A/C head. (Refer to item 2-2)

(Refer to SERVICING FIXTURE AND TOOLS) 2. Confirm that the reflected picture of stamp mark is appeared on the tape prior to P4 Post as shown in Fig. 2-2-A. a) When the reflected picture is distorted, turn the screw 1 clockwise until the distortion is disappeared. b) When the reflected picture is not distorted, turn the screw 1 counterclockwise until little distortion is appeared, then adjust the a). 3. Turn the screw 2 to set the audio level to maximum. 4. Confirm that the bottom of the Audio/ Control Head and the bottom of the tape is shown in Fig. 2-2-C. c) When the height is not correct, turn the screw 3 to adjust the height. Then, adjust the 1~3 again.

Check if the relation between Audio and Envelope waveform becomes (1) or (2) of Fig. 2-1-A. 2-4: CONFIRM HI-FI AUDIO (Hi-Fi model only) 1. Connect CH-1 of the oscilloscope to TP4001, CH-2 to TP1002 and CH-3 to the Hi-Fi Audio Out Jack. 2. Playback the VHS Alignment Tape (JG001P or JG001Q). (Refer to SERVICING FIXTURE AND TOOLS) 3. Press and hold the Tracking-Auto button on the remote control more than 2 seconds to set tracking to center. 4. Press the Tracking Up button and count number of steps which the audio output is changed from Hi-Fi (10KHz) to MONO (6KHz). 5. Press the Tracking Down button and count number of steps which the audio output is changed from Hi-Fi (10KHz) to MONO (6KHz). 6. Confirm that the difference between these counted steps number in the above items are within 2 steps. If the difference are more than 3 steps, do Tape Running Adjustment again. (Refer to item 2-3)
