10、t. 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 must beused during servicing of the unit.1) When testing and/or repairing any component within the product, keep your eyes and

11、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

12、 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/or plastic(where applicable) components may also contain traces of chemicals found by the C

13、alifornia Health and WelfareAgency (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 FOR ANYREASON WHATSOEVER!Avoid prolonged, unprotected contact between solder and your skin!

14、When soldering, do not inhale solder fumes orexpose 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 turn

15、ed to the “ON” position, the laser component will emita beam for several seconds to detect if a disc is present. During this time (5-10 sec.) the laser may radiate through thelens of the laser pick-up unit. Do not attempt any servicing during this period!If no disc is detected, the laser will stop e

16、mitting the beam. When a disc is set, 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

17、 provided elsewhere in thismanual. Adjustment of this control can increase the laser emission level from the device.All of the P.C.B.s installed in this unit are soldered using the lead free solder.Among some types of lead free solder currently available, it is recommended to use one of the followin

18、g types for the repairwork. Sn + Ag + Cu (tin + silver + copper) Sn + Cu (tin + copper) Sn + Zn + Bi (tin + zinc + bismuth)Caution:As the melting point temperature of the lead free solder is about 30C to 40C (50F to 70F) higher than that of the lead solder, be sureto use a soldering iron suitable to

Such components commonly are calledElectrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits an

21、d some field-effect transistorsand semiconductor “chip” components. The following techniques should be used to help reduce the incidence of componentdamage caused by electro static discharge (ESD).1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain of

22、f any ESD onyour body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging ESD wriststrap, which should be removed for potential shock reasons prior to applying power to the unit under test.2. After removing an electrical assembly equipped with ES dev

23、ices, place the assembly on a conductive surface such asaluminum foil, to prevent electrostatic charge buildup or exposure of the assembly.3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.4. Use only an anti-static solder removal device. Some solder removal devices not clas

24、sified as “anti-static (ESD protected)”can generate electrical charge sufficient to damage ES devices.5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES devices.6. Do not remove a replacement ES device from its protective package until immediately

25、before you are ready to install it. (Mostreplacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or compa-rable conductive material).7. Immediately before removing the protective material from the leads of a replacement ES divice, touch the prot

26、ective materialto the chassis or circuit assembly into which the device will be installed.CAUTION: Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion su

27、ch as thebrushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity (ESD)sufficient to damage an ES device).Grounding for electrostatic breakdown prevention1.

28、lectricity from your body.2. Work table grounding.Put a conductive material (sheet) or steel sheet on the area where the optical pickup is placed and ground the sheet.Caution:The static electricity of your clothes will not be grounded through the wrist strap.
