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.
