13、 beam component. This component may emit invisible, as well as visible radiation, which maycause eye damage. To protect your eyes and skin from laser radiation, the following precautions must be used duringservicing of the unit.1) When testing and/or repairing any component within the product, keep

14、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 proced

15、ures other than those specified herein may result inhazardous radiation exposure.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

16、-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 set, you will not be exposed to any laseremissions.2) The laser power level can be adjusted with th

17、e 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.I TO SERVICE PERS

26、SW100I PREVENTION OF ELECTRO STATIC DISCHARGEThe laser diode in the traverse unit (optical pickup) may be damaged due to static electricity from clothes or the human body.Use caution to prevent electrostatic damage when servicing or handling the laser diode.1. Grounding for electrostatic damage prev

27、entionSome devices, such as the DVD player, use an optical pickup (laser diode) that will be damaged by static electricity in theworking environment. Only attempt service after ensuring that all grounding procedures have been completed.1. Worktable groundingPut a grounded conductive material (sheet)

28、 or iron sheet on the area where the optical pickup is placed.2. Human body groundingUse an anti-static wrist strap to discharge the static electricity from your body.2. Handling of the optical pickup1. To prevent damage to the optical pickup replacement parts during transportation and before instal

29、lation, both ends of thelaser diode are short-circuited. After installing the new part, remove the short circuit according to the correct procedure inthis service manual.2. Do not use a tester to check the laser diode in the optical pickup. The power supply in the tester will damage the laserdiode.3

30、. Handling Precautions for the Traverse Unit (Optical Pickup)1. Handle the traverse unit (optical pickup) gently, as it is an extremely high-precision assembly.2. The flexible cable lines may break if an excessive force is applied to it. Use caution when handling the cable.3. The semi-fixed resistor

31、 for laser power adjustment should not be adjusted.
