In addition, other electrical/electronic and/or plastic (whereapplicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (andpossibly 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 ANY REA-SON WHATSOEVER!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 beforehandling food.1. Critical Components InformationComponents having special characteristics aremarked s and must be replaced with parts havingspecifications equal to those originally installed.2. Leakage Current Measurement (For 120V ModelsOnly)When service has been completed, it is imperative toverify that all exposed conductive surfaces are prop-erly insulated from supply circuits.GMeter impedance should be equivalent to 1500 ohmsshunted by 0.15F.GLeakage current must not exceed 0.5mA.GBe sure to test for leakage with the AC plug in bothpolarities.I TO SERVICE PERSONNEL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。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 is recommended to use one of the following types for therepair work. 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 solderis about 30C to 40C (50F to 70F) higher than that ofthe lead solder, be sure to use a soldering iron suitableto each solder.About lead free solder / 無鉛WARNING: 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 must beused 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.RadioFans.CN 收音机爱 好者资料库DVD-S17003DVD-S1700Laser Emitting conditions:1) When the Top Cover is removed, and the STANDBY/ON SW is turned 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 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)790 nm (VCD/CD)Output Power:1.45 mW (DVD)1.13 mW (VCD/CD)Beam divergence:60 degreesVARO!: AVATTAESSA JA SUOJALUKITUSOHITETTAESSA OLET ALTTIINANKYMTTMLLE LASER-STEILYLLE.
