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 THE SURFACE OF THE OBJECTIVE
LENS ON THE OPTICAL PICK-UP BLOCK.
Caution: Invisible laser radiation when
open and interlocks defeated avoid
exposure to beam.
Advarsel: Usynlig laserståling ved åbning,
når sikkerhedsafbrydere er ude af funktion.
Undgå udsættelse for stråling.
VAROITUS!
Laiteen Käyttäminen muulla kuin tässä käyttöohjeessa
mainitulla tavalla saataa altistaa käyt-täjän
turvallisuusluokan 1 ylittävälle näkymättömälle
lasersäteilylle.
VARNING!
Om apparaten används på annat sätt än vad som
specificeras i denna bruksanvising, kan användaren
utsättas för osynling laserstrålning, som överskrider
gränsen för laserklass 1.
PROTECTION OF EYES FROM LASER BEAM DURING SERVICING
CAUTION
Use of controls or adjustments or performance of proce-
dures other than those specified herin may result in
hazardous radiation exposure.
ATTENTION
Lutillisation de commandes, réglages ou procédures
autres que ceux spécifiés peut entraîner une dangereuse
exposition aux radiations.
ADVARSEL
Usynlig laserståling ved åbning, når sikkerhedsafbrydereer
ude af funktion. Undgå udsættelse for stråling.
This Compact Disc player is classified as a CLASS 1

Precaution to replace Optical block
(KSS-213F)
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.
1) After the connection, remove solder shown in
right figure.
