Thiscomponent may emit invisible, as well as visible radiation,which may cause eye damage. To protect your eyesand skin from laser radiation, the foll
21、owing precautionsmust be used during servicing of the unit.1) When testing and/or repairing any component within theproduct, keep your eyes and skin more than 30 cmaway from the laser pick-up unit at all times. Do notstare at the laser beam at any time.2) Do not attempt to readjust, disassemble or r

23、to the ON position, the lasercomponent will emit a beam for several seconds todetect if a disc is present. During this time (5-10 sec.)the laser may radiate through the lens of the laser pick-up unit. Do not attempt any servicing during this period!If no disc is detected, the laser will stop emittin
