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

[Microprocessor version display]
• If the following operation is performed during the POWER OFF
in the modes other than the POWER SAVE mode (i.e., while the
Demo display shows the watch time),
1. When three buttons of STOP , ENTER , V (CUSOR DOWN)
are pressed at the same time, the MC and the GC microprocessor
version numbers are displayed as “M1.19 G1.00”.
2. When three buttons of STOP , ENTER , v (CUSOR UP) are
pressed at the same time, the model name and destination are
displayed as “BG2V ASIA3”.

[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 and display status.
• If no error occurs:
The aging operation continues repeatedly.
1. Operating method of Aging Mode
Turn on the main power and select “CD” of the function.
1) Set a disc in DISC1 tray. Select ALL DISC CONTINUE, and REPEAT OFF.
2) Load the tapes recording use into the decks A and B respectively.
3) Press three buttons x , ENTER , and
DISC SKIP EX-CHANGE simultaneously.
4) Aging operations of CD and tape are started at the same time.
5) To exit the aging mode, perform [MC Cold Reset].

2) Operation during aging mode
In the aging mode, the program is executed in the following
sequence.
(1) The disc tray opens and closes.
(2) The mechanism accesses DISC 2 and makes an attempt to
read TOC. However, since there are no discs, a message
“CD2 NO DISC” appears.
(3) The mechanism accesses DISC 3 and a message “CD3 NO
DISC” appears.
(4) The disc tray turns to select a disc1.
(5) A disc is chucked.
(6) TOC of disc is read.
(7) The pickup accesses to the track 1, and playing 2 seconds.
(8) The pickup accesses to the last track, and playing 2 seconds.
(9) Every time when an aging operation of step 1 to step 8 is
complete, the display “AGING[*][*][*][*]” value increases
as the number of aging operations is counted up.
(10) Returns to step 1.

(4) A tape is reversed, and the tape on REV side is played for 2
minutes.
The tape on the REV side is played in both A and B.
(5) Rewind is executed up to the top of tape.
(6) Returns to step 2, and repeat steps from 2 to 5.
[VIDEO CD Color-bars Mode]
On this mode, the data of the color-bars signal as a picture signal
and the 1 kHz sine wave signal as a sound signal are output by the
mechanism controller (IC502) 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-bars signal can be observed at CN301
(VIDEO OUT) using an oscilloscope.
Procedure:
1. Short the both ends of the land of SL503 of the VIDEO board.
2. Turn the power on. Press the CD button to select CD.
3. The color-bars appears when the CD is in stop status, and it
disappears when the CD goes in play status.
4. After measuring, remove the lead wire connected.VIDEO board

[CD Servo ON/OFF Mode]
Procedure:
1. Short SL502 on the VIDEO board by soldering.

3. Press the hH button to play back CD.
4. When the > + button is pressed, 100 track jump is executed.
5. Also, every pressing of the PLAY MODE button triggers
between ON and OFF of TRACKING SERVO and SLED
SERVO.
How to quit the CD servo ON/OFF mode:
1. Press the ?/1 button to turn off the main power.
2. Remove soldering from SL502.
