Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270 ˚C dur-
ing 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 ra-
diation exposure.

NOTES  ON  HANDLING  THE  OPTICAL  PICK-UP
BLOCK  OR  BASE  UNIT
The laser diode in the optical pick-up block may suffer electro-
static 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 emis-
sion, 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.
• RELEASING  THE  DISC  TRAY  LOCK
The disc tray lock function for the antitheft of an demonstration
disc in the store is equipped.
Releasing Procedure :
Press two buttons of
Z
(CD) and 
[GROOVE]
 simultaneously for
five seconds. The message “UNLOCKED” is displayed and the
tray is unlocked.
Note:
When “LOCKED” is displayed, the tray lock is not released by
turning power on/off with the 
[I/   ]
 button.
SERVICE  POSITION
In checking the DSP/MC board, prepare jig (extension cable J-
2501-208-A: 1.25 mm Pitch, 21 cores, Length 370 mm).
