SAFETY-RELATED COMPONENT WARNINGII

COMPONENTS IDENTIFIED BY MARK A 0R DOTTED LINE
WITH MARK A ON THE SCHEMATIC DIAGRAMS AND IN
THE PARTS LISTIARE CRITICAL T0 SAFE OPERATION.

REPLACE THESE COMPONENTS WITH SONY PARTS
WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS

' MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.

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 differ»
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 30cm away from
the objective lens.
