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

The laser diode in the optical pickup block may suffer electrostate
ic 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 em' 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 waveform is output several times.

CAUTION

Use of controls or adjustments or performance oi procedures
other than those specified herein may result in hazardous radia-
tion exposure.

This appliance is classified as
a CLASS 1 LASER product.
This marking is located on the
rear or bottom exterior.

NOTES ON CHIP COMPONENT REPLACEMENT

- Never reuse a disconnected chip component.

- Notice that the minus side of a tantalum capacitor may be dame
aged by heat.

FLEXIBLE CIRCUIT BOARD REPAIRING

' Keep the temperature of 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 unsolderingi
