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
COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS
APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS
PUBLISHED BY SONY.

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.

Design and specifications are subject to change without notice.

TEST MODE

[Cold Reset]

• The cold reset clears all data including preset data stored in the
RAM to initial conditions. Execute this mode when returning
the set to the customer.

Procedure:

1. Press three buttons x , DISPLAY , and DISC 1

simultaneously.

2. The fluorescent indicator tube becomes blank instantaneously,

and the set is reset.

[Tuner Step Change] (Except for European and Middle Eastern
models)

• A step of AM channels can be changed over between 9 kHz and
10 kHz.

Procedure:

1. Press `/1 button to turn the set ON.

2. Select the function “TUNER”, and press TUNER/BAND button

to select the BAND “AM”.

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 “AM 9 k STEP”
or “AM 10 k STEP”, and thus the channel step is changed over.

• Change of function MD or VIDEO ( also the input level changes).

Procedure:

1. Press `/1 button to turn the set ON.

2. Press MD (VIDEO) and `/1 buttons simultaneously, and

the display of fluorescent indicator tube changes to “MD” or

[MC Test Mode]

• This mode is used to check operations of the respective sections
of Amplifier, Tuner, and Tape.

Procedure:

• To enter MC Test Mode

1. Press `/1 button to turn on the set.

2. Press three buttons of x , DISPLAY and DISC 3

simultaneously.

3. Cursor segment flash on the FL display tube. The input

1. When VOLUME control knob is turned clockwise even slightly,

the sound volume increases to is maximum and a message
“VOLUME MAX” appears for two seconds, then the display
returns to the original display.

2. When VOLUME control knob is tuned 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.

[GC Test Mode]

• This mode is used to check the software version, FL tube, LED,
keyboard and VACS.

Procedure:

1. Press three buttons x , DISPLAY , 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 stating from

MC version, GC version, DVD version, CDDM, CDMA,
CDMB, BDA, BDB version, ST version, TA version, TM
version, TC 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

“KOJOVO”. 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.

* Tuner function

1. 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. (It means that the
memory is cleared.)

2. The minimum, center and maximum frequency of each band is
set then.

* Tape recording test

1. To enter the MC Test Mode.

2. Load tapes in both tape decks A and B.

3. Press the REC button to start recording.

4. Pressing M , m buttons during recording returns the tape
to the recording start position and stops it at this position.

5. Pressing the “High Speed Dubbing” key while playing back the
tape of deck B switches the playback speed between “Normal
Speed” and “High Speed”.

Note:

When the playback direction of the tape is set to other than “ONY
WAY”, the restriction on the number of times playback which can
be repeated will be cleared.

* AMS Test Mode

1. Set TAPE function

2. Select the desired loop by pressing PLAY MODE button.
Insert a test tape AMS-110A or AMS-120 to Deck A.

3. Press SPECTRUM or KARAOKE PON button to enter the
AMS test mode.

4. After a tape is rewound first, the FF AMS is checked, and the
mechanism is shut off after detecting the AMS signal the AMS
signal twice.

5. Then the REW AMS is checked and the mechanism is shut off
after detecting the AMS signal twice.

6. When the check is complete, a message of either OK or NG
appears.

* To return to normal mode again.

1. When you want to exit this mode, press `/1 button.

2. The cold reset is enforced at the same time.
