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.
LASER DIODE AND FOCUS SEARCH OPERATION
CHECK
Carry out the “S curve check” in “CD section adjustment” and check
that the S curve waveforms is output three times.
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 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.

Note:
• Always move the pick-up to most inside track when exiting
from this mode. Otherwise, a disc will not be unloaded.
• Do not run the sled motor excessively, otherwise the gear can
be chipped.
CHANGE-OVER OF AM TUNER STEP BETWEEN 9 kHz
AND 10 kHz
• A step of AM channels can be changed over between 9 kHz and
10 kHz.
Procedure:
1. Press 1/u button to turn the set ON.
2. Select the function “TUNER”, and press TUNER/BAND
button to select the BAND “AM”.
3. Press 1/u button to turn the set OFF.
4. Press ENTER/NEXT and 1/u buttons simultaneously, and
the display of fluorescent indicator tube changes to “AM 9 k
STEP” or “AM 10 k STEP”, and thus the channel step is changed
over.
Be sure not to change with carelessness.
LED AND FLUORESCENT INDICA TOR TUBE ALL LIT, KEY
CHECK MODE
Procedure:
1. Press three buttons GROOVE , ENTER/NEXT , and
DISC 3 simultaneously.
2. LEDs and fluorescent indicator tube are all turned on.
Press DISC 2 button, and the key check mode is activated.
3. In the key check mode, the fluorescent indicator tube displays
“K 1 J0 V0”. Each time a button is pressed, “K”value increases.
However, once a button is pressed, it is no longer taken into
account.
“J” value increases like 1, 2, 3 ... if rotating JOG dial knob in
“clock wise” direction, or it decreases like 0, 9, 8 ... if rotating
in “counter clock wise” direction.
“V” value increases like 1, 2, 3 ... if rotating VOLUME knob
in “+” direction, or it decreases like 0, 9, 8 ... if rotating in “–”
direction.
4. To exit from this mode, press three buttons in the same manner
as step 1, or disconnect the power cord.
SELF-DIAGNOSIS
This model has the self-diagnosis function for the video and audio
decoder sections.
Immediately after the power on, the self-diagnosis function searches
each operation of IC’s around the mechanism controller (IC701).
The LED (D701) on the VIDEO board indicates their results.

AGING MODE
This mode can be used for operation check of CD section and tape
deck section.
• If an error occurred:
The aging operation stops.
• If no error occurs:
The aging operation continues repeatedly.
1. Aging Mode in CD Section
1-1. Operating Method of Aging Mode
1. Set discs in DISC 1 and DISC 3 trays.
2. Select the function “CD”.
3. Press three buttons GROOVE , ENTER/NEXT ,
and DISC 5 simultaneously.
4. The aging mode is activated, if a changer mark on the
fluorescent indicator tube is blinking.
5. In the aging mode, the aging is executed in a sequence given
in “1-2. Operation during Aging Mode”.
The aging continues unless an alarm occurred.
6. To exit from the aging mode, press 1/u button to turn the
set OFF.
• If a button other than buttons In CD section is pressed during
aging, the aging in the CD section is finished.
• To execute aging to the tape deck section successively,

2-2. Operation during Aging Mode
In the aging mode, the program is executed in the following
sequence.
1. A tape on FWD side is played for one minute.
2. PAUSE STOP is made.
3. Recording is made for 3 minutes. (For the deck not having
the record function, the play is executed. In this case, ·
LED does not light up.)
4. FF is executed up to the end of tape.
5. A tape is reversed, and the tape on REV side is played for
one minute.
6. PAUSE STOP is made.
7. Recording is made for 3 minutes. (For the deck not having
the record function, the play is executed. In this case, ª
LED does not light up.)
8. FF is executed up to the end of tape.
9. Steps 1 through 8 are executed for the other deck.
10. Steps 1 through 9 are repeated unless an alarm occurred.
2-3. Deck Selection Sequence
• During the aging mode, decks are selected in the following
sequence:

VIDEO CD COLOR BAR MODE
On this mode, the data of the color bar signal as a picture signal and
the 1 kHz sine wave signal as a sound signal are output by the
mechanism controller (IC701) for the video CD signal check. When
measurement of the voltage and waveform on the VIDEO board,
perform it in this mode.
For reference, the color bar signal can be observed at J9001 (VIDEO
OUT) and the sound signal can be observed at J101 (VIDEO
(AUDIO) OUT) using an oscilloscope.
Procedure:
1. Turned power switch on.
2. Press the FUNCTION button to select the CD.
3. Connect the SL701 on the VIDEO board with solder.
4. After measuring, remove the soldering installed.

THIS NOTE IS COMMON FOR PRINTED WIRING
BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this necessary note is printed in each
block.)
For schematic diagrams.
Note:
• All capacitors are in µF unless otherwise noted. pF: µµF
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ω and 1/
specified.
• % : indicates tolerance.
¢
•
: internal component.
• 2 : nonflammable resistor.
• 1 : fusible resistor.
• C : panel designation.
Note:
The components identified by mark ! or dotted
line with mark ! are critical for safety.
Replace only with part
number specified.
• U : B+ Line.
• V : B– Line.
• H : adjustment for repair.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production tolerances.
• Waveforms are taken with a oscilloscope.
• Circled numbers refer to waveforms.
• Signal path.
F : FM
g : VIDEO/MD
E : PB (DECK A)
d : PB (DECK B)
G : REC (DECK B)
J : CD
I : PHONO
For printed wiring boards.
Note:
• X : parts extracted from the component side.
®
•
•
• b : Pattern from the side which enables seeing.
: Through hole.
¢
: internal component.

W or less unless otherwise
Note:
Les composants identifiés par
une marque ! sont critiques
pour la sécurité.
Ne les remplacer que par une
piéce portant le numéro
spécifié.
