For these reasons,we advise all YAMAHA product owners that any service required should be performed by an authorizedYAMAHA Retailer or the appointed service representative.IMPORTANT:The presentation or sale of this manual to any individual or firm does not constitute authorization, certification orrecognition of any applicable technical capabilities, or establish a principle-agent relationship of any form.The data provided is believed to be accurate and applicable to the unit(s) indicated on the cover. The research, engineering, andservice departments of YAMAHA are continually striving to improve YAMAHA products. Modifications are, therefore, inevitableand specifications are subject to change without notice or obligation to retrofit. Should any discrepancy appear to exist, pleasecontact the distributors Service Division.WARNING:Static discharges can destroy expensive components. Discharge any static electricity your body may haveaccumulated by grounding yourself to the ground buss in the unit (heavy gauge black wires connect to this buss).IMPORTANT:Turn the unit OFF during disassembly and part replacement. Recheck all work before you apply power to the unit.RadioFans.CN 收音机爱 好者资料库DVD-S23002DVD-S2300WALLOUTLETEQUIPMENTUNDER TESTAC LEAKAGETESTER OREQUIVALENTINSULATINGTABLEWARNING: 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 (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.WARNING: Laser SafetyThis product contains a laser 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 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.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 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 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 PERSONNEL1. Critical Components InformationComponents having special characteristics are marked sand 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.GMeter impedance should be equivalent to 1500 ohm shuntedby 0.15F.GLeakage current must not exceed 0.5mA.GBe sure to test for leakage with the AC plug in both polarities.THE DVD PLAYER SHOULD NOT BE ADJUSTED OR REPAIRED BY ANYONE EXCEPT PROPERLY QUALIFIEDSERVICE PERSONNEL.RadioFans.CN 收音机爱 好者资料库DVD-S23003DVD-S2300Laser Diode PropertiesType:Semiconductor laser GaAlAsWave length:658 nm (DVD)790 nm (VCD/CD)Output Power: CLASS IIa 1mW (DVD)CLASS I1mW (VCD/CD)VARO!:AVATTAESSA JA SUOJALUKITUS OHITETTAESSA OLET ALTTIINA NKYMTTMLLE LASER-STEILYLLE.

Grounding for Electrostatic Damage PreventionSome 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) 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 installation, 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. 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 for laser power adjustment should not be adjusted. Do not turn the resistor.1MConductive material(sheet) or iron sheetAnti-static wrist strap12425542635I LOCALE MANAGEMENT INFORMATIONLocale Management Information : This DVD player is designed and manufactured to respond to the Locale ManagementInformation that is recorded on the DVD disc.
