PROTECTION OF EYES FROM LASER BEAM DURING SERVICING
VAROITUS!
Laiteen Käyttäminen muulla kuin tässä käyttöohjeessa mainit-
ulla tavalla saattaa altistaa käyt-täjän turvallisuusluokan 1 ylit-
tävälle 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: Invisible laser radiation when
open and interlocks defeated avoid expo-
sure to beam.
Advarsel:Usynling laserståling ved åbning,
når sikkerhedsafbrydere er ude af funktion.
Undgå udsættelse for stråling.
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.
The CLASS 1 LASER PRODUCT label is located on the rear
exterior.
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.

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

How to Adjust the Rotating Phase of the
Gear, Main Cam
1) Push down the hooking catch of the CHAS. MECH, and
remove the TRAY.
2) Align the arrow mark of the Gear, Main Cam with the black
round mark of the CHAS, MECHA as shown below.
3) Confirm that the Slide, Mech Cam is located in the right
position, then insert the TRAY gently.
Caution: If the rotating phase of the Gear, Main Cam is
incorrectly adjusted, the chucking operation and
tray movement will have malfunction.
Align the arrow 2mark with the black
round • mark.

Note) • PCMD is the two’s complement output with MSB first.
• GTOP monitors the protection status of the Frame Sync. (H: Sync protection window opened).
• XUGF is the Frame Sync negative pulse which is obtained from the EFM signal. This is the signal before the sync protection.
• XPLCK is the inverted signal of the EFM PLL clock. The PLL works so that the fall-down edge and the changed point of the
EFM signal agree.
• GFS is the signal that goes “H” when the Frame Sync and the internally inserted timing agree.
• RFCK is the signal having 136 micro-seconds (during normal speed) that is generated to have the same accuracy as X’tal.
• C2PO is the signal indicating the error status of the data.
• XRAOF is the signal that is generated when the 16k RAM goes outside the jitter margin ±4F.
