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.

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.

Power requirements 12 V DC car battery

(negative ground)

Dimensions Approx. 178 × 50 × 179 mm

(w/h/d)

Mounting dimensions Approx. 182 × 53 × 161 mm

(w/h/d)

Mass Approx. 1.2 kg

Supplied accessories Parts for installation and connections (1 set)

Front panel case (1)

Design and specifications are subject to change without

notice.

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, ob-

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

Notes on Chip Component Replacement

•Never reuse a disconnected chip component.

•Notice that the minus side of a tantalum capacitor may be dam-

aged by heat.

SERVICE NOTES

This label is located on the bottom of the chassis.

TEST DISCS

This set can playback CD-R and CD-ROM discs. The following

test discs should be used to check the capability:

CD-R test disc TCD-R082LMT (Part No. J-2502-063-1)

CD-RW test disc TCD-W082L (Part No. J-2502-063-2)

Notes on CD-R/CD-RW discs

•You can play CD-Rs (recordable CDs)/CD-RWs (rewritable CDs)

designed for audio use on this unit.

Look for these marks to distinguish CD-Rs/CD-RWs for audio

use.

These marks denote that a disc is not for audio use.

•Some CD-Rs/CD-RWs (depending on the equipment used for

its recording or the condition of the disc) may not play on this

unit.

•You cannot play a CD-R/a CD-RW that is not finalized*.

*A process necessary for a recorded CD-R/CD-RW disc to be

played on the audio CD player.

z UNLEADED SOLDER

Boards requiring use of unleaded solder are printed with the lead

free mark (LF) indicating the solder contains no lead.

(Caution: Some printed circuit boards may not come printed with

the lead free mark due to their particular size.)

: LEAD FREE MARK

Unleaded solder has the following characteristics.

• Unleaded solder melts at a temperature about 40°C higher than

ordinary solder.

Ordinary soldering irons can be used but the iron tip has to be

applied to the solder joint for a slightly longer time.

Soldering irons using a temperature regulator should be set to

about 350°C.

Caution: The printed pattern (copper foil) may peel away if the

heated tip is applied for too long, so be careful!

•Strong viscosity

Unleaded solder is more viscous (sticky, less prone to flow)

than ordinary solder so use caution not to let solder bridges

occur such as on IC pins, etc.

•Usable with ordinary solder

It is best to use only unleaded solder but unleaded solder may

also be added to ordinary solder.

EXTENSION CABLE AND SERVICE POSITION

When repairing or servicing this set, connect the jig (extension cable)

as shown below.

•Connect the MAIN board (CNP301) and the SERVO board (CN1)

with the extension cable (Part No. J-2502-076-1).
