SERVICING NOTES

Flexible Circuit Board Repairing

0 Keep the temperature of the soldering iron around 270 C
during repairing.

0 Do not touch the soldering iron on the same conductor of
the circuit board (within 3 times).

0 Be careful not to apply force on the conductor when solder-
ing or unsolderingi

Notes on chip component replacement

0 Never reuse a disconnected chip component.
a Notice that the minus side of a tantalum capacitor may be
damaged by heat.

NOTES ON HANDLING THE OPTICAL
PICK-UP BLOCK OR BASE UNIT

The laser diode in the optical pick-up block may suffer elec<
trostatic breakdown because of the potential difference gen~
erated by the charged electrostatic load, etc. on clothing and
the human body.

During repair. pay attention to electrostatic breakdown 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.
