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. This Compact Disc player is classified as a CLASS 1 LASER product.
