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.

Precaution to replace Optical block
(SF-P101NR)
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.
