Thiscomponent may emit invisible, as well as visible ra-diation, which may cause eye damage. To protectyour
12、 eyes and skin from laser radiation, the followingprecautions must be used during servicing of the unit.1) When testing and/or repairing any component withinthe product, keep your eyes and skin more than 30cm/1 feet away from the laser pick-up unit at all times.Do not stare at the laser beam at any
13、time.2) Do not attempt to readjust, disassemble or repair thelaser pick-up, unless noted elsewhere in this manual.3) CAUTION: Use of controls, adjustments or perform-ance of procedures other than those specified hereinmay result in hazardous radiation exposure.Laser Emitting conditions:1) When the T
14、op Cover is removed, and the STANDBY/ON SW is turned to the ON position, the laser compo-nent will emit a beam for several seconds to detect if adisc is present. During this time (5-10 sec.) the lasermay radiate through the lens of the laser pick-up unit.Do not attempt any servicing during this peri
15、od!If no disc is detected, the laser will stop emitting thebeam. When a disc is loaded, you will not be exposedto any laser emissions.2) The laser power level can be adjusted with the VR onthe pick-up PWB, however, this level has been set bythe factory prior to shipping from the factory. Do notadjus
16、t this laser level control unless instruction is pro-vided elsewhere in this manual. Adjustment of this con-trol can increase the laser emission level from thedevice.警告:安全対策本機光線放射部品搭載。部品放射光線目損傷起。光線目及肌保護、本機修理作業中下記注意厳守。1) 時修理時、目及肌光30c 以上離。場合光線見。2) 光再調整及分解。3) 上指定以外制御、調整、手順光線照射結果招恐。放射条件1) 取外STANDBY/ON O
