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
1) After the connection, remove solder shown in
the figure below.
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.

Operation
• Test mode is activated.
• CD block power is ON.
• Laser diode turns always ON.
• Continual focus search
(The pickup lens repeats the full-
swing up-down motion.)
* Avoid continual searches that last for
more than 10 minutes.
* NOTE 1
• Normal playback
• Focus search is continued if TOC
cannot be read. * NOTE 1
• During normal disc playback
Press once; tracking servo OFF
Press twice; tracking servo ON
* NOTE 2
• Pickup moves to the outermost track
• Pickup moves to the innermost track
* NOTE 3
(During playback, machine operates
normally.)

1. How to Activate CD Test Mode
Insert the AC plug while pressing the function CD button.
All FL display tubes will light up, and the test mode will be
activated.
2. How to Cancel CD Test Mode
Either one of the following operations will cancel the CD test
mode.
• Press the function button. • Press the power switch button.
(except CD function button) • Disconnect the AC plug
3. CD Test Mode Functions
When test mode is activated, the following mode functions from No.1 to No.5 can be used by pressing the operation keys.
* NOTE 1: There are cases when the tracking servo cannot be locked owing to the protection circuit being operated when heat builds up
in the driver IC if the focus search is operated continually for more than 10 minutes. In these cases the power supply should be
switched off for 10 minutes until heat has been reduced and then re-started.
* NOTE 2: Do not press the fior flkeys when the machine is in the ;status is active. If they are pressed, playback will not be possible
after the ;status has been canceled. If the fior flkeys are pressed in the ;status, press the 9key and return to the start mode
(No.1).
* NOTE 3: When pressing the fior flkeys, take care to avoid damage to the gears. Because the sled motor is activated when the fior fl
keys are pressed, even when the pick-up is at the outermost or innermost track.
4. Operation Outline
The operation of each mode is carried out in the direction of the arrows from the start mode as indicated in the following illustration.
If the DISC DIRECT PLAY button is pressed, the machine performs the same operation as the PLAY button is pressed as shown. If
the tray is opened by pressing OPEN/CLOSE button during Play mode or Traverse mode, the machine returns to the Start mode.
