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 di-
terence 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 objec»
tive lens in the optical pick-up block. Therefore, when
checking the laser diode emission, observe from more
than 30cm away from the objective lens.

SAFETY-RELATED COMPONENT WARNING I!

COMPONENTS IDENTIFIED BY MARK & OR DOTTED
LINE WITH MARK A ON THE SCHEMATIC DIAGRAMS
AND IN THE PARTS LIST ARE CRITICAL TO SAFE
OPERATION. REPLACE THESE COMPONENTS WITH
