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

The laser diode in the optical pick-up block may suffer
electrostatic 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 emission, observe from more than 30 cm away from the
objective lens.
