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.

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.

CLEANING OBJECTIVE LENS OF OPTICAL PICK-UP
• In cleaning the objective lens of optical pick-up, be sure the
following below.
1. In cleaning the lens, do not apply an excessive force.
As the optical pick-up is vulnerable, application of excessive
force could damage the lens holder.
force could damage the lens holder.
2. In cleaning, do not use a cleaner other than exclusive cleaning
liquid (KK-91 or isopropyl alcohol).
3. Wipe the objective lens spirally from center toward outside.
