Critical Components InformationComponents having special characteristics are marked Zand must be replaced with parts having specifications equalto those originally installed.2. Leakage Current Measurement (For 120V Models Only)When service has been completed, it is imperative to verifythat all exposed conductive surfaces are properly insulatedfrom supply circuits.Meter impedance should be equivalent to 1500 ohmsshunted by 0.15F.AC LEAKAGETESTER OREQUIVALENTEQUIPMENTUNDER TESTINSULATINGTABLEWALLOUTLETWARNING: Laser SafetyThis product contains a laser beam component. 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 mustbe 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 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 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 (whereapplicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and possiblyother 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 ANY REASONWHATSOEVER!Avoid prolonged, unprotected contact between solder and your skin! 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 before handlingfood.Leakage current must not exceed 0.5mA.Be sure to test for leakage with the AC plug in bothpolarities.About Lead Free Solder / 無鉛All of the P.C.B.s installed in this unit and solder joints aresoldered using the lead free solder.Among some types of lead free solder currently available, it isrecommended to use one of the following 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 isabout 30C to 40C (50F to 70F) higher than that of the leadsolder, be sure to use a soldering iron suitable to each solder.本機搭載基板付接合部無鉛付。無鉛種類、 修理時下記無鉛使用推奨。Sn+Ag+Cu （錫 +銀 +銅）Sn+Cu （錫 +銅）Sn+Zn+Bi （錫+亜鉛 +）注意：無鉛融点温度通常鉛入比3040 程度高、合使用。3DVX-1000DPX-1200DVX-1000Laser 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 (5-10 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 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 instruction is provided elsewhere in thismanual. Adjustment of this control can increase the laser emission level from the device.Laser Diode PropertiesType:Semiconductor laser GaAlAsWave length:650 nm (DVD)784 nm (VCD/CD)Output Power:7 mW (DVD/VCD/CD)Beam divergence:60 degreeWARNINGThe use of optical instruments with this product will increase eye hazard.Repair handling should take place as much as possible with a disc loaded inside the player.Warning for power supplyThe primary side of the power supply carries live mains voltage when the player is connected to the mains even whenthe player is switched off !This primary area is not shielded so it is possible to touch copper tracks and/or components when servicing the player.Service personnel have to take precautions to prevent touching this area or components in this area.Note:The screws on the DVD mechanism 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.4DVX-1000DVX-1000 PREVENTION OF ELECTROSTATIC DISCHARGE LOCALE MANAGEMENT INFORMATIONLocale Management Information : This DVD player is designed and manufactured to respond to the LocaleManagement Information that is recorded on a DVD disc.
