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.

NOTES ON HANDLING THE OPTICAL PICK-UPBLOCK OR BASE UNIT

The laser diode in the optical pick-up block may suffer electrostat-

ic break-down because of the potential difference generated by thecharged 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 CHECKThe laser beam on this model is concentrated so as to be focused

on the disc reflective surface by the objective lens in the optical

pickup block. Therefore, when checking the laser diode emission,

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

SERVICE NOTES

CAUTIONUse of controls or adjustments or performance of procedures other than

those specifi

ed herein may result in hazardous radiation exposure.

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.

TABLE OF CONTENTS

UNLEADED SOLDERBoards 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 MARKUnleaded 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.

This compact disc player is classified as a CLASS 1 LASER

product. The CLASS 1 LASER PRODUCT label is located on the

exterior.

This label is located on the bottom of the chassis.
