3 PROTECTION OF EYES FROM LASER BEAM DURING SERVICING VAROITUS! Laiteen KŠyttŠminen muulla kuin tŠssŠ kŠyttšohjeessa mainit- ulla tavalla saattaa altistaa kŠyt-tŠjŠn turvallisuusluokan 1 ylit- tŠvŠlle nŠkymŠttšmŠlle lasersŠteilylle. VARNING! Om apparaten anvŠnds pŒ annat sŠtt Šn vad som specificeras i denna bruksanvising, kan anvŠndaren utsŠttas fšr osynling laserstrŒlning, som šverskrider grŠnsen fšr laserklass 1.Caution: Invisible laser radiation when open and interlocks defeated avoid expo- sure to beam. Advarsel: Usynling laserstŒling ved Œbning, nŒr sikkerhedsafbrydere er ude af funktion. UndgŒ uds¾ttelse for strŒling. 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, rŽglages ou procŽdures autres que ceux spŽcifiŽs peut entra”ner une dangereuse exposition aux radiations. ADVARSEL! Usynlig laserstŒling ved Œbning, nŒr sikkerhedsafbrydereer ude af funktion. UndgŒ uds¾ttelse for strŒling. This Compact Disc player is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT label is located on the rear exterior. 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.
