To protect your eyesand skin from laser radiation, the following precautionsmust be used during servicing of the unit.1) When testing and/or repairing any component withinthe product, keep your eyes and skin more than 30 cmaway from the laser pick-up unit at all t

14、imes. Do notstare at the laser beam at any 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 perfor-mance of procedures other than those specified hereinmay result in hazardous radiation expo

In addition, other electrical/electronic and/or plastic(where applicable) components may also contain traces of chemicals found by the California Health and WelfareAgency (and possibly other entiti

16、es) to cause cancer and/or birth defects or other reproductive harm.DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANYREASON WHATSOEVER!Avoid prolonged, unprotected contact between solder and your skin!

18、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 emitting thebeam. When a disc is loaded, you will not be exposedto

19、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.
