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
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.

(3) Install the repair jig as follows;
1) Install the P.W.B. JIG into the unit and fix it with
screws. (Refer to Fig-3).
(4) Attach the parts as follows, (Refer to Fig-4);
1) Attach the supplied transistor to the location of the
P.W.B. MAIN from which Q623 is removed in
step (2).
2) Connect the supplied PWB FLEX to CON1.
• When the CONTROL UNIT is not used, use the
P.W.B. KEY instead. (Refer to step (6), How to
use the repair jig.)
3) Connect the FFC cable to CON101 and pickup.
(The supplied FFC cannot be used because pitches
and number of pins are different.)

(5) Perform wirings to the C.Bs. Refer to Fig-5/-6;
• Be sure to connect the wires coming from the
P.W.B. JIG to
MAIN C.B as follows.
1) Connect the motor wires and sensor (PD201)
wires that are removed in step (2) to the P.W.B.
JIG.
2) Connect all wires coming from the P.W.B. JIG to
the respective lands of the MAIN C.B by
soldering.
• Connect the motor wires (BLU/WHT) of the
P.W.B. JIG to the motor wire connecting lands on
the MAIN C.B by soldering.
• Connect the LED (LED201) wires (RED/GRY) of
the P.W.B. JIG to the LED wire connecting lands
on the MAIN C.B by soldering.
