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
laserstrÂlning, som ˆ verskrider gr‰nsen fˆ r 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, rÈglages ou procÈdures autres que
ceux spÈcifiÈs peut entraÓner une dangereuse exposition aux
radiations.

ADVARSEL!

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
