SERVICING NOTES
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.

Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270 ˚C dur-

• 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.

POWER SUPPLY DURING SERVICING
• As this set has not own power supply, it does not operate inde-
pendently.
Therefore, during servicing, connect it to the Pre-Main ampli-
fier Unit (TA-EX880/MS717) of DHC-EX880MD/MD717.
Also, connect the Tuner Unit (ST-EX880/MS717) because the
POWER switch is not provided to the Pre-Main amplifier Unit
(TA-EX880/MS717).
