This component may emit invisible, as well as visible radiation,which may cause eye damage. To protect your eyes and skin from laser radiation, the following precautions mustbe used during servicing of the unit.1) When testing and/or repairing any component within the product, keep your eyes and skin more than 30 cm away fromthe laser pick-up unit at all times. Do not stare at the laser beam at any time.2) Do not attempt to readjust, disassemble or repair the laser pick-up, unless noted elsewhere in this manual.3) CAUTION : Use of controls, adjustments or performance of procedures other than those specified herein may result inhazardous radiation exposure.WARNING: CHEMICAL CONTENT NOTICE!The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/orplastic (where applicable) components may also contain traces of chemicals found by the California Health andWelfare Agency (and possibly other entities) to cause cancer and/or birth defects or other reproductive harm.DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FORANY REASON WHATSOEVER!Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumesor expose eyes to solder/flux vapor!If you come in contact with solder or components located inside the enclosure of this product, wash your handsbefore handling food.Laser Emitting conditions:1) When the Top Cover is removed, and the STANDBY/ON SW is turned to the ON position, the laser component willemit a beam for several seconds to detect if a disc is present. During this time (5-10 sec.) the laser may radiate throughthe 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 the beam. When a disc is loaded, you will not be exposed to any laseremissions.2) The laser power level can be adjusted with the VR on the pick-up PWB, however, this level has been set by the factoryprior to shipping from the factory. Do not adjust this laser level control unless instruction is provided elsewhere in thismanual. Adjustment of this control can increase the laser emission level from the device.THE DVD AUDIO/VIDEO PLAYER SHOULD NOT BE ADJUSTED OR REPAIRED BY ANYONE EXCEPT PROPERLY QUALIFIEDSERVICE PERSONNEL.RadioFans.CN 收音机爱 好者资料库3DVR-C310DPX-1200DVR-C310Laser Diode PropertiesType:Semiconductor laser GaAlAsWave length:650 nm (DVD)784 nm (VCD/CD)Output Power:7 mW (DVD/VCD/CD)Beam divergence:60 degreeVARO!: AVATTAESSA JA SUOJALUKITUS OHITETTAESSA OLET ALTTIINA NKYMTTMLLELASER-STEILYLLE.
