Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
Flexible Circuit Board Repairing
• Keep the temperature of the 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.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation exposure.
This appliance is classified as a CLASS 1 LASER product.
The CLASS 1 LASER PRODUCT MARKING is located on
the rear exterior.
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated
by the charged electrostatic load, etc. on clothing and the human
body.
During repair, pay attention to electrostatic break-down and also
use the procedure in the printed matter which is included in the
repair parts.
The flexible board is easily damaged and should be handled with
care.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused
on the disc reflective surface by the objective lens in the optical
pick-up block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.
SERVICE POSITION
In checking the CD block, prepare jig (extension cable J-2501011-B).
Laser component in this product is capable of emitting radiation
exceeding the limit for Class 1.
The following caution label is located inside the unit.
CAUTION :
INTERLOCKS DEFEATED. AVOID EXPOSURE TO BEAM.

DECK SECTION
Note: Confirm each contents of this section first of all. If the results are
not satisfied, do the adjustment.
0 dB=0.775 V
1. Demagnetize the record/playback head with a head
demagnetizer.
2. Do not use a magnetized screwdriver for the adjustments.
3. After the adjustments, apply suitable locking compound to the
parts adjust.
4. The adjustments should be performed with the rated power
supply voltage unless otherwise noted.
5. The adjustments should be performed in the order given in this
service manual. (As a general rule, playback circuit adjustment
should be completed before performing recording circuit
adjustment.)
6. The adjustments should be performed for both L-CH and RCH.
7. Switches and controls should be set as follows unless otherwise
specified.

CD SECTION
Notes:
1. CD block basically constructed to operate without adjustment. Therefore, check each item in order given.
2. Use YEDS-18 disc (Part No.: 3-702-101-01) unless otherwise indicated.
3. Use the oscilloscope with more than 10 MΩ impedance.
4. Clean an object lens by an applicator with neutral detergent when the
signal level is low than specified value with the following checks.
S-Curve Confirmation
Connection:
Procedure:
1. Connect an oscilloscope to IC703 pin qg and TP (VC) on the
CD board.
2. Connect between TP (FOK) and TP (GND) on the CD board
by lead wire.
3. Turn the power ON.
4. Press the
[EJECT ] (CD) button to open the disc tray, and
put the disc (YEDS-18).
5. Press the
[EJECT ] (CD) button to close the disc tray (Actu-
ate the focus search).
6. Conf irm that the wav eform on the oscilloscope is symmetrical
between A and B and that peak to peak level is within 3.0 ±
1.0 Vp-p.
S-curve waveform
7. After confirmation, disconnect the lead wire in step 2.
Note: • Try to measure several times to make sure that the ratio of A : B
or B : A is more than 10 : 7.
• Take sweep time as long as possible and light up the brightness
to obtain best waveform.

Connection:
Procedure:
1. Connect an oscilloscope to IC703 pin qh and TP (VC) on the
CD board.
2. Turn the power ON.
3. Load the disc (YEDS-18), and press the
u
[ ] button to play-
back the disc.
4. Confirm that the waveform on the oscilloscope is clear and
that the RF signal level is correct.
Note: Clear RF signal waveform means that the shape “◊” can be clearly
distinguished at the center of the waveform.
