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:Usynling laserståling ved åbning,
når sikkerhedsafbrydere er ude af funktion.
Undgå udsættelse for stråling.

VAROITUS!

Laiteen Käyttäminen muulla kuin tässä käyttöohjeessa mainit­ulla tavalla saattaa 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 herein may result in hazardous
radiation exposure.

ATTENTION

L'utilisation 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-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
the right figure.

DISASSEMBLY INSTRUCTIONS

1. How to replace PICK UP.

1) Open the TRAY.
Push the stopper to arrow direction and release half of
the SHAFT SLED.

2) Turn GEAR MAIN CAM to the counterclockwise
(arrow “a”) direction, and lift up CD mechanism. (Fig-1)

3) Remove SHAFT SLED.

4) CD mechanism in down position, replace PICK UP.

5) Lift up CD mechanism (Fig-1), and Reassemble the
SHAFT SLED.

2. How to remove the 5CD CHANGER BLOCK
(Fig-2)

1) Remove the two FFC of the CD circuit board, and

remove the five SCREWS.

2) Lift 5 CD CHANGER BLOCK from behind, and

remove it. (5CD CHANGER BLOCK can be removed
even if PANEL TRAY is not removed.)

1) Push the PLATE GEAR’S Boss at the bottom part of
CHAS MECHA strongly to the outside (arrow “b”
direction). (Fig-3)
(Confirm that TRAY appears a little in the front.)

2) Draw TRAY to the open position.

3) Remove FFC, and push the two LEVERS at both side of
the CHAS MECH to remove TRAY. (Fig-4)

3-2. Reassembling procedure.

1) Confirm that LEVER TRAY is at the most right position
and check for the CD Mechanism to be in the down
position. (Fig-5)

2) Push in the TRAY along the rail of the CHAS MECHA.

4. How to reassemble the TURN TABLE. (Fig-7)

1) Push LEVER TT in the direction of “C”, and put in the
TURN TABLE 5CD. (Fig-7)
After reassembly, one of the TURN TABLE DISC
TRAY (can be either one of the five disc trays) must be
aligned with TURN TABLE 5CD. (Fig-8)
That is, having no gap difference between the TURN
TABLE 5CD and the TRAY 5CD.

* When reassembling the TURN TABLE 5CD, it is

acceptable facing any CD number (1-5).
