COMPONENTS  IDENTIFIED  BY  MARK  0  OR  DOTTED  LINE
WITH  MARK  0  ON  THE  SCHEMATIC  DIAGRAMS  AND  IN
THE  PARTS  LIST  ARE  CRITICAL  TO  SAFE  OPERATION.
REPLACE  THESE  COMPONENTS  WITH  SONY  PARTS
WHOSE  PART  NUMBERS  APPEAR  AS  SHOWN  IN  THIS
MANUAL  OR  IN  SUPPLEMENTS  PUBLISHED  BY  SONY.

Use of controls or adjustments or performance of procedures other
than those specified herein may result in hazardous radiation
exposure.

This compact disc player is classified as a CLASS 1 LASER
product. The CLASS 1 LASER PRODUCT label is located on the
exterior.

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 difference 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 from more than 30 cm away from the objective lens.

This label is located on the bottom of the chassis.

Notes on Chip Component Replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be damaged

by heat.

If the optical pick-up block is defective, please replace the whole
optical pick-up block.
Never turn the semi-fixed resistor located at the side of optical pick-
up block.

TEST DISCS
Please use the following test discs for the check on the voltage and
