22、ich may cause eyedamage. To protect your eyes and skin from laser radiation, the following pre-cautions must be 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 from the laser pick-upunit at all times. D

23、o 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 perform-ance of procedures other than those specified herein may result in hazardousradiation exposure.

24、Laser Emitting Conditions:1) When the Top Cover is removed, and the STANDBY/ ON SW is turned to the “ON” position, the laser compo-nent will emit a beam forseveral seconds to detect if a disc is present. During this time (510 sec.) the laser may radiate through the lens of the laser pick-up unit.Do

25、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 laser emissions.2) The laser power level can be adjusted with the VR on the pick-up PWB, however, this level has been set by the factory p

26、rior to shippingfrom the factory. Do not adjust this laser level control unless instruction is provided elsewhere in this manual. Adjustment of this controlcan increase the laser emission level from the device.Laser Diode PropetiesType:Semiconductor laser GaAlAsWave length:650 nm (DVD)780 nm (VCD/CD
