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.
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. This
label is located on the
rear exterior.
UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size)
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.
MODEL IDENTIFICATION
– Back Panel –
Part No.
: LEAD FREE MARK
Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40 °C higher
than ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350 °C.
Caution: The printed pattern (copper foil) may peel away if
the heated tip is applied for too long, so be careful!
• Strong viscosity
Unleaded solder is more viscou-s (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.
• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.

TEST MODE
[CMN (MC) TEST MODE]
•This mode is used to check operations of Amplifier.
Procedure:
1. Press the ?/1 key to turn the power ON.
2. Press three keys of [DSGX], [FUNCTION] and [TUNER/BAND]
simultaneously.
3. When the CMN (MC) test mode is activated, “s” blinks
on the liquid crystal display.
4. Turn the [BASS] knob counterclockwise, “TONE MIN” is
displayed on the liquid crystal display. Turn the [BASS] knob
clockwise, “TONE MAX” is displayed on the liquid crystal
display.
Turn the [TREBLE] knob clockwise or counterclockwise,
“TONEFLAT” is displayed on the liquid crystal display.
Turn the [VOLUME] knob counterclockwise, “VOL MIN” is
displayed on the liquid crystal display. Turn the [VOLUME]
knob clockwise, “VOL MAX” is displayed on the liquid crystal
display.
5. To release this mode, press the ?/1 key.
[PANEL (GC) TEST MODE]
•This mode is used to check the liquid crystal display, LED,
model, destination, software version and key.
Procedure:
1. Press the ?/1 key to turn the power ON.
2. Press three keys of [DSGX], [DISPLAY] and [FUNCTION]
simultaneously.
3. Liquid crystal display and LEDs are all turned on.
4. When you want to enter the model, destination and version
display mode, press the [REPEAT] key. The model and
destination are displayed alternately on the liquid crystal
display.
5. Each time [REPEAT] key is pressed, the display changes
starting from MD version, MC version, GC version, CD
version, CDD version, CDMA version, CDMB version, BDA
version, BDB version, ST version, TA version, TM version,
and TC version this order, and returns to the MD version
display on the liquid crystal display.
6. When [FUNCTION] key is pressed while the version numbers
are being displayed except model and destination, year, month
and day of the software creation display. When [FUNCTION]
key is pressed again, the display returns to the software version
display. When [REPEAT] key 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 on the liquid crystal display in the same order of
version display.
7. Press the [PLAY MODE/DIRECTION] key, the key check mode
is activated.
8. In the key check mode, the liquid crystal display displays “K0”.
Each time a key is pressed, “K” value increases. However,
once a key is pressed, it is no longer taken into account.
9. To release this mode, press three keys in the same manner as
step 2, or disconnect the power cord.
[SHIP MODE (NO MEMORY CLEAR) ]
•This mode moves the optical pick-up to the position durable
to vibration. Use this mode when returning the set to the
customer after repair.
Procedure:
