PROTECTION OF EYES FROM LASER BEAM DURING SERVICINGThis set employs laser. Therefore, be sure to follow carefully the instructions below when servicing.

CAUTIONUse of controls or adjustments or performance of procedures other than those specified herin may result in hazardous radiation exposure.

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: Usynlig laserstling ved bning, nr sikkerhedsafbrydere er ude af funktion. Undg udsttelse for strling.

ATTENTIONLutillisation de commandes, rglages ou procdures autres que ceux spcifis peut entraner une dangereuse exposition aux radiations.

ADVARSELUsynlig laserstling ved bning, nr sikkerhedsafbrydereer ude af funktion. Undg udsttelse for strling. This Compact Disc player is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT label is located on the rear exterior.
