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.
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.
CAUTION
Use of controls or adjustments or performance of procedures other than those specified herin may result in
hazardous radiation exposure.
ATTENTION
L’utillisation 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
LASER product.

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 right figure.

TEST MODE
1. How to activate CD test mode
1) Remove D937 (1SS133) from the main circuit board, and connect
the terminal No.45 of a microcomputer and GND line with a wire.
(Fig. 1)
2) Connect +12V to ACC/BACK UP and – (minus) to the ground of
CONNECTOR ASSY.
3) Turn on the power.
Test mode will be activated and turn on all LCD lights (5 seconds
later, only the display will change to Demo Mode.) (Fig. 2)
Fig. 1
2. How to cancel CD test mode
1) Turn off the power supply to ACC/BACK UP.
2) Remove the connection wire between the terminal No.45 of the
main circuit board and the GND line, and solder back D937
(1SS133).
3) Disconnect +12V from ACC/BACK UP and – (minus) from the
ground of CONNECTOR ASSY.

• Press the REPEAT key to release each mode.
* NOTE 1 : There is a case that the CD cannot be operated owing to the protection circuit being operated when heat builds up in the driver IC if
the focus search is opereated continually for more than 10 minutes.
In this case, the power supply should be switched off for 10 minutes until the heat has been reduced and then re-start.
