SERVICING NOTES

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

The laser diode in the optical pick-up block may suffer
electrostatic breakdown because of the potential dififeb
ence generated 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.

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 emission, observe more than 30 cm away from

the objective lens.

LASER DIODE AND FOCUS SEARCH OPERATION

CHECK

1. Turn POWER switch on with no disc inserted and disc
table closed,

2. Confirm that the following operation is performed

while observing the objecting lens
E 6 © °
