The following caution label is located inside of the unit.

This appliance is classified

as a CLASS 1 LASER

product.

The CLASS 1 LASER

PRODUCT MARKING is

located on the rear exterior.

CAUTION

Use of controls or adjustments or performance of procedures

other than those specified herein may result in hazardous

radiation exposure.

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.

Flexible Circuit Board Repairing

• Keep the temperature of soldering iron around 270˚C

during repairing.

• Do not touch the soldering iron on the same conductor of the

circuit board (within 3 times).

• Be careful not to apply force on the conductor when soldering

or unsoldering.

SAFETY-RELATED COMPONENT WARNING!!

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.

SERVICING NOTE

HOW TO OPEN THE DISC TRAY WHEN POWER SWITCH

TURNS OFF

Insert a tapering driver into the aperture of the unit bottom, and turn

in the direction of arrow.

Use a flat (–) head screwdriver to open the CD tray by manual opera-

tion. (Flat head screwdriver with nominal blade length of 3mm.)

To close the disc table, turn the driver in the reverse direction.

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.

Pull out disc table.

CD-TEXT TEST DISC

This unit is able to display the TEXT data (character information)

written in the CD on its fluorescent indicator tube.

The CD-TEXT TEST DISC (TGCS-313: J-2501-126-A) is used

for checking the display.

To check, perform the following procedure.

Procedure:

1. Turn ON the power and set the test disc.

2. Press the H button and play back the disc.

3. The following will be displayed on the fluorescent indicator

tube.

Display : 1kHz/0 dB/– – – –
