When soldering, do not inhale solder fumes or exposeeyes to solder/flux vapor!If you come in contact with solder or components located inside the enclosure of this product, wash your hands beforehandling food.WARNING: Laser SafetyThis product contains a laser beam component.

12、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 your eyes and ski

13、n more than 30 cm away fromthe laser pick-up unit at all times. Do not stare the laser beam at any time.2) Do not attempt readjustment, disassemble or repair of the laser pick-up, unless noted elsewhere in this manual.3) CAUTION: Use of controls, adjustments or performance of procedures other than t

14、hose specified herein may result inhazardous radiation exposure.Laser Emitting conditions:1) When the Top Cover is removed, and the POWER SW is turned to the ON position, the laser component will emit abeam for several seconds to detect if a disc is present. During this time (5 - 10 sec.) the laser

15、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 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 the VR on pick-up PWB,

16、 however, this level has been set by the factory priorto shipping from the factory. Do not adjust this laser level control unless instruction is provided elsewhere in this manual.Adjustment of this control can increase the laser emission level from the device.I TO SERVICE PERSONNEL1.

25、AUWarning for power supplyThe primary side of the power supply including the heatsink carries live mains voltage when the player isconnected to the mains even when the player is switched off !This primary area is not shielded so it is possible to touch copper tracks and/or components when servicing

26、the player.Service personnel have to take precautions to prevent touching this area or components in this area .The primary side of the power supply has been indicated with a lightening stroke and a stripe-marked print on the printedwiring boardNote:The screws on the DVD mechanism (position 18-1 in

27、on the exploded view drawing) may never be touched,removed or re-adjusted.Handle the DVD mechanism with care when the unit has to be exchanged!The DVD mechanism is very sensitive for dropping or giving shocks.DVD-S510/DV-S53503I PREVENTION OF ELECTROSTATIC DISCHARGESome semiconductor (solid state) d

28、evices can be damaged easily by static electricity. Such components commonly arecalled Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effecttransistors and semiconductor “chip” components. The following techniques should be used to hel

29、p reduce the incidence ofcomponent damage caused by electro static discharge (ESD).1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any ESD onyour body by touching a known earth ground. Alternatively, obtain and wear a commercially available di

30、scharging ESDwrist strap, 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 devices, place the assembly on a conductive surface such asaluminum foil, to prevent electrostatic charge buildup or

31、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 classified as “anti-static (ESD protected)”can generate electrical charge sufficient to damage ES devices.5. Do not us

32、e 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 before you are ready to install it.(Most replacement ES devices are packaged with leads electrically shorted toget

33、her by conductive foam, aluminum foil orcomparable conductive material).7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protectivematerial to the chassis or circuit assembly into which the device will be installed.CAUTION: Be sure no power

34、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 such as thebrushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate sta

35、tic electricity (ESD)sufficient to damage an ES device).HANDLING PRECAUTIONSThe laser diode in the optical pickup may break down due to potential difference caused bystatic electricity of clothes or human body. So be careful of electrostatic breakdown duringrepair of the DVD mechanism.Grounding for

36、electrostatic breakdown prevention1. Human body grounding.Use the antistatic wrist strap to discharge the static electricity fromyour body.2. Work table grounding.Put a conductive material (sheet) or steel sheet on the area wherethe optical pickup is placed and ground the sheet.Caution:The static el

37、ectricity of your clothes will not be grounded through thewrist strap. So take care not to let your clothes touch the opticalpickup.I LOCALE MANAGEMENT INFORMATIONLocale Management Information : This DVD player is designed and manufactured to respond to the Locale ManagementInformation that is recor
