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 pickup block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.
Laser component in this product is capable
of emitting radiation exceeding the limit for
Class 1.
This appliance is classified as a CLASS 1 LASER product. The
CLASS 1 LASER PRODUCT MARKING is located on the rear
exterior.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous 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.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH
MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS
LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE

memory. The hot reset mode functions same as if the power
cord is plugged in and out.
Procedure:
1. Press three buttons x , ENTER , and DISC 1 simultaneously.
2. The fluorescent indicator tube becomes blank instantaneously,
and the set is reset.

Procedure:
1. Press ?/1 button to turn the set ON.
2. Select the function “CD”.
3. Press three buttons x , ENTER , and OPEN/CLOSE simul-
taneously.
4. The CD service mode is selected.
5. With the CD in stop status, turn the shuttle knob clockwise to
move the pickup to outside track, or turn the shuttle knob
counter-clockwise to inside track.
6. To exit from this mode, perform as follows:
1) Move the pickup to the most inside track.
2) Press three buttons in the same manner as step 2.
Note: • Always move the pickup 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 MW Tuner Step between 9 kHz and

2. Select the function “TUNER”, and press TUNER/BAND
button to select the BAND “MW”.
3. Press ?/1 button to turn the set OFF.
4. Press ENTER and ?/1 buttons simultaneously, and the display
of fluorescent indicator tube changes to “MW 9 k STEP” or
“MW 10 k STEP”, and thus the channel step is changed over.
[GC Test Mode]
• This mode is used to check the software version, FL tube, LED,
keyboard and VACS.
Procedure:
1. Press three buttons x , ENTER , and DISC 2 simultaneously.
2. LEDs and fluorescent indicator tube are all turned on.
3. When you want to enter the software version display mode,
press DISC 1 . The model number and destination are displayed.
4. Each time DISC 1 is pressed, the display changes starting
from MC version, GC version, VC version, CD version, CM
version, ST version, TC version, TA version, TM version and
BR version in this order, and returns to the model number and
destination display.
5. When DISC 3 is pressed while the version numbers are being
displayed except model number and destination, year, month
and day of the software creation appear. When DISC 3 is
pressed again, the display returns to the software version display.
When DISC 1 is pressed while year, month and day of the
software creation are being displayed, the year, month and day
of creation of the software versions are displayed in the same
order of version display.
6. Press DISC 2 button, and the key check mode is activated.
7. In the key check mode, the fluorescent indicator tube displays
“KEY0 VOL0”. Each time a button is pressed, “KEY” value
increases. However, once a button is pressed, it is no longer
taken into account.
“VOL” value increases like 1, 2, 3 ... if rotating VOLUME
knob in “+” direction, or it decreases like 0, 9, 8 ... if rotating in
“–” direction.
8. Also when DISC 3 is pressed after lighting of all LEDs and FL
tubes, value of VACS appears.
9. To exit from this mode, press three buttons in the same manner
as step 1, or disconnect the power cord.
[VACS ON/OFF Mode]

its maximum and a message “GEQ ALL MA” appears.
5.When F (CURSOR DOWN) button is pressed, GEQ decreases
to its minimum and a message “GEQ ALL M1” appears.
6.When g (CURSOR LEFT) or G (CURSOR RIGHT) button
is pressed, GEQ is set to flat and a message “GEQ FLAT”
appears.
7.When the VOLUME control knob is turned clockwise even
slightly, the sound volume increases to its maximum and a
message “VOLUME MAX” appears for two seconds, then the
display returns to the original display.
8.When the VOLUME control knob is turned counter-clockwise
even slightly, the sound volume decreases to its minimum and
a message “VOLUME MIN” appears for two seconds, then
the display returns to the original display.
9.In the test mode, the default-preset channel is called even when
the TUNER is selected and an attempt is made to call the preset
channel that has been stored in memory, by operating the Shuttle
knob. (It means that the memory is cleared.)
10. When CD is selected and the EDIT button is pressed, the disc
that is being chucked at this moment becomes the default
setting. It means that the default disc only is accessed when
any other discs are selected even though the display indication
changes accordingly. At the same time, the DISC SKIP EXCHANGE and OPEN/CLOSE cannot be accepted. (It means
that the tray motor and the turntable motor are disabled of their
operation.)
11. When a tape is inserted in Deck B and recording is started, the
input source function selects VIDEO automatically.
12. When x button is pressed to stop recording, the Tape (Deck)
B is selected and tape is rewound using the Shuttle knob, tape
is rewound, tape is stops at around the record-starting position
and playback of the recorded portion of the tape is started. If
PAUSE is inserted even once during recording, tape is rewound
to the position around the PAUSE position and is played back.
13. When the CD SYNC HI-DUB Button is press during playback
of Deck B, either normal speed or high speed can be selected
by this button.
14. Select the desired loop by pressing the PLAY MODE button.
Insert a test tape AMS-110A or AMS-RO to Deck A.
15. Press the SPECTRUM button to enter the AMS test mode.
16. After a tape is rewound first, the FF AMS is checked, and the
mechanism is shut off after detecting the AMS signal twice.
17. Then the REW AMS is checked and the mechanism is shut off
after detecting the AMS signal twice.
18. When the check is complete, a message of either OK or NG
appears.
19. When you want to exit this mode, press the ?/1 button twice.
The cold reset is enforced at the same time.

When set to the test mode performed in Tape Speed Adjustment,
when the tape is rewound after recording, the “REC memory mode”
which rewinds only the recorded portion and playback is set.
This “REC memory mode” is convenient for performing this
adjustment. During recording, the input signal FUNCTION will
automatically switch to VIDEO.

Note :
1. CD Block is basically designed to operate without adjustment.
Therefore, check each item in order given.
2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated.
3. Use an oscilloscope with more than 10MΩ impedance.
4. Clean the object lens by an applicator with neutral detergent
when the signal level is low than specified value with the
following checks.
S-Curve Check
Procedure:
1.Supply a 28 dB 98 MHz signal from the ANTENNA terminal.
2.Tune the set to 98 MHz.
3.Adjust RV611 to the point (moment) when the TUNED
indicator will change from going off to going on.

3. Connect between TP (AGCCON) and TP (GND) by lead wire.
4. Turn Power switch on.
5. Load a disc (YEDS-18) and actuate the focus search. (In
consequence of open and close the disc tray, actuate the focus
search)
6. Confirm that the oscilloscope waveform (S-curve) is
symmetrical between A and B. And confirm peak to peak level
