PROTECTION OF EYES FROM LASER BEAM DURING SERVICING
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.
s Caution: Invisible laser radiation when
open and interlocks defeated avoid
exposure to beam.
s 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.
CAUTION
Use of controls or adjustments or performance of procedures 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-710A)
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

TEST MODE
There are two methods to perform operation check using test mode. One method uses the head unit. The other method uses the repair
jig. Because different operation buttons must be used for entering the operation modes and there are cases that unit does not run at all,
in the method that uses the head unit, the method using the repair jig is described as follows;
1. How to start up the CD test mode
Connect the P.W.B Key in accordance SERVICE JIG AND TOOLS step (6). How to use the repair jig - When the Control
Unit (CDC/CT) is not used .
1) While pressing the STOP button of the P.W.B Key, turn on the +12 V power of ACC/BACK UP.
2. How exit the CD test mode

During the PLAY mode, the REV, FWD and DISC UP keys are invalid. Press the STOP key once.
When a Head Unit is connected, the Disc No. and the Track No. are shown on display in the same way as in the normal
operation.
Note 1: If the focus search operation is continued for 10 minutes or longer, the driver IC heats up sufficiently to trigger the
protection circuit, which stops the CD system. Turn off the main power and re-start operation about 10 minutes later.
