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.

s Caution: Invisible laser radiation when

open and interlocks defeated avoid
exposure to beam.

s Advarsel: Usynlig laserståling ved åbning,

når sikkerhedsafbrydere er ude af funktion.
Undgå udsættelse for stråling.

VAROITUS!

Laiteen Käyttäminen muulla kuin tässä käyttöohjeessa
mainitulla tavalla saataa 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 herin may result in
hazardous radiation exposure.

ATTENTION

L’utillisation 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.
