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 laserstÂling ved Âbning,
nÂr sikkerhedsafbrydere er ude af funktion.
Undg udsÊ ttelse for strÂling.
VAROITUS!
Laiteen K‰ytt‰minen muulla kuin t‰ss‰ k‰yttˆ ohjeessa mainitulla tavalla saattaa altistaa k‰yt-t‰j‰n turvallisuusluokan 1 ylitt‰v‰lle n‰kym‰ttˆ m‰lle lasers‰teilylle.
VARNING!
Om apparaten anv‰nds p annat s‰tt ‰n vad som specificeras i
denna bruksanvising, kan anv‰ndaren uts‰ttas fˆ r osynling

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, rÈglages ou procÈdures autres que
ceux spÈcifiÈs peut entraÓner une dangereuse exposition aux
radiations.
ADVARSEL!

Precaution to replace Optical block
(KSS-213B/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.

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 mark with the black
round mark.

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.
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.

• Test mode is activated.
• Laser diode turns always ON.

• Continual focus search
(The pickup lens repeats the fullswing up-down motion.)
* Avoid continual searches that last for
more than 10 minutes.
• 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
• Pickup moves to the outermost track
• Pickup moves to the innermost track
(During playback, machine operates
normally.)
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

• FL display check (All displays light.)
• APC circuit check
• Laser current measurement

• Check focus search waveform
• Check focus error waveform

*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 or keys when the machine is in the
after the

*NOTE 3: When pressing the or keys, take care to avoid damage to the gears. Because the sled motor is activated when the fi or fl
keys are pressed, even when the pick-up is at the outermost or innermost track.
