PROTECTION OF EYES FROM LASER BEAM DURING SERVICING

VAROITUS!

Laiteen Kyttminen muulla kuin tss kyttohjeessa mainit-

ulla tavalla saattaa altistaa kyt-tjn turvallisuusluokan 1 ylit-

tvlle nkymttmlle lasersteilylle.

VARNING!

Om apparaten anvnds p annat stt n vad som specificeras i

denna bruksanvising, kan anvndaren utsttas fr osynling

laserstrlning, som verskrider grnsen fr laserklass 1.

Caution: Invisible laser radiation when

open and interlocks defeated avoid expo-

sure to beam.

Advarsel:Usynling laserstling ved bning,

nr sikkerhedsafbrydere er ude af funktion.

Undg udsttelse for strling.

CAUTION

Use of controls or adjustments or performance of procedures

other than those specified herein may result in hazardous

radiation exposure.

ATTENTION

L'utilisation de commandes, rglages ou procdures autres que

ceux spcifis peut entraner une dangereuse exposition auxradiations.

ADVARSEL!

Usynlig laserstling ved bning, nr sikkerhedsafbrydereer ude

af funktion. Undg udsttelse for strling.

This Compact Disc player is classified as a CLASS 1 LASER

product.

The CLASS 1 LASER PRODUCT label is located on the rear

exterior.

This set employs laser. Therefore, be sure to follow carefully the

instructions below when servicing.

WARNING!

WHEN SERVICING, DO NOT APPROACH THE LASER EXIT

WITH THE EYE TOO CLOSELY. IN CASE IT IS NECESSARY TO

CONFIRM LASER BEAM EMISSION. BE SURE TO OBSERVE

FROM A DISTANCE OF MORE THAN 30cm FROM THESURFACE OF THE OBJECTIVE LENS ON THE OPTICAL

PICK-UP BLOCK.

Precaution to replace Optical block(KSM-260E)

1) After the connection, remove solder shown in

the right figure.

Body or clothes electrostatic potential could ruin

laser diode in the optical block. Be sure ground

body and workbench, and use care the clothes

do not touch the diode.
