This component may emit invisible, as well as visible radiation, which maycause eye damage. To protect your eyes and skin from laser radiation

16、, the following precautions must be used duringservicing 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, disa

17、ssemble 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.Laser Emitting conditions:1) When the the STANDBY/ON key is turned to the ON p

18、osition, and the cover is open, the laser component will emit abeam for several seconds to detect if a disc is present. During this time (5-10 sec.) the laser may radiate through the lensof the laser pick-up unit. Do not attempt any servicing during this period!If no disc is detected, the laser will

19、 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 inst

20、ruction is provided elsewhere in thismanual. Adjustment of this control can increase the laser emission level from the device.RadioFans.CN 收音机爱 好者资料库TSX-10/15/20TSX-10/15/20Optical Pick-up2VARO!:AVATTAESSA JA SUOJALUKITUS OHITETTAESSA OLET ALTTIINA NKYMTTMLLE LASER-STEILYLLE.
