Class 1.
CAUTION
Use of controls or adjustments or performance of procedures
otherthan thosespecified herein mayresult inhazardous radiation
exposure.
Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be
damaged by heat.
Flexible Circuit Board Repairing
• Keep the temperature of soldering iron around 270˚C
during repairing.
• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering
or unsoldering.

2. Demagnetize the record/playback head with a head
demagnetizer.
3. Do not use a magnetized screwdriver for the adjustments.
4. After the adjustments, apply suitable locking compound to the

AMTuningVoltage Adjustment
Procedure:
1. Set the reception frequency of the unit to 530 kHz.
2. Adjust L105 for 1.2 ± 0.05 V reading on the DC voltmeter.
3. Set the reception frequency of the unit to 1,710 kHz.
4. Confirm that the voltage reading on the DC voltmeter is within
8.0 ± 0.5 V.
Adjustment Location: MAIN board (See page 13)
AMTracking Adjustment
Procedure:
1. Tune the set to 600 kHz.
2. Set the output ofAM RF SSG so that the input level of the set
will become 60 dB (µV/m).
3. Adjust L104 so that when the waveform on the oscilloscope is
maximum, no noise appears.
4. Tune the set to 1,400 kHz.
5. Adjust TC102 so that when the waveform on the oscilloscope
is maximum, no noise appears.
• Repeat the procedures in each adjustment several times, and the
tracking adjustment should be finally done by the trimmer
capacitors.

Note:
1. CD Block is basically constructed to operate without
adjustment. Therefore, check each item in order given.
2. UseYEDS-18 disc (3-702-101-01) unless otherwise indicated.
3. Use an oscilloscope with more than 10MΩimpedance.
4. Clean the object lens by an applicator with neutral detergent
when the signal level is low than specified value with the
following checks.
5. Adjust the focus bias adjustment when optical pick-up block is
replaced.
RF Level Check
Procedure :
1. Connect oscilloscope to test point TP01 on CD DECODER
board.
2. Turned Power switch on.
3. Put disc (YEDS-18) in and playback.
4. Confirm that oscilloscope waveform is clear and check RF
signal level is correct or not.
Note: Clear RF signal waveform means that the shape “◊” can be
clearly distinguished at the center of the waveform.
