2、understood by the users, and have therefore not been restated.WARNING:Failure to follow appropriate service and safety procedures when servicing this product may result in personalinjury, destruction of expensive components and failure of the product to perform as specified. For these reasons,we adv

3、ise all YAMAHA product owners that all 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 applic

4、able 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. Mod

5、ifications are, therefore, inevitableand specifications are subject to change without notice or obligation to retrofit. Should any discrepancy appear to exist, please contactthe distributors Service Division.WARNING:Static discharges can destroy expensive components. Discharge any static electricity

6、 your body may have accumu-lated 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 parts replacement.

This component may emit invisible, as well as visible radiation,which may cause eye damage. To protect your eyes and skin from laser

9、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 the laser beam at any time.2) Do not attempt readjustmen

10、t, disassemble or repair of the laser pick-up, unless noted elsewhere in this manual.3) CAUTION : Use of controls, adjustments or preformance of procedures other than those specified herein may result inhazardous radiation exposure.1. Critical Components InformationComponents having special characte

11、ristics 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

12、.GMeter impedance should be equivalent to 1500 ohm shuntedby 0.15F.GLeakage current must not exceed 0.5mA.I TO SERVICE PERSONNELWARNING: CHEMICAL CONTENT NOTICE!The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/orplastic (where applicable)

13、components may also contain traces of chemicals found by the California Health andWelfare Agency (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 FORANY REASON WHATSOEVER!Avoid

14、 prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumesor expose 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.GBe sure to test for leakage

15、with the AC plug in bothpolarities.Laser Emitting conditions:1) When the Top Cover is removed, and POWER SW is turned to the ON position, the laser component will emit a beamfor several seconds to detect if a disc is present. During this time (5-10 sec.) the laser may radiate through the lens ofthe

16、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 VR on pick-up PWB, however, this level has been set by t

17、he factory prior toshipping from the factory. Do not adjust this laser level control unless instruuction is provided elsewhere in this manual.Adjustment of this control can increase the laser emission level from the device.RadioFans.CN 收音机爱 好者资料库CDR-S1000CDR-S10002Laser Diode PropertiesMaterial: GaA

Using a standard disc (TDK CD-RXA74 or TDK CD-RWXA74), check if recording and playback are executable.CAUTION: How to handle discs Handle the disc with special care not to scratch it or

43、 make it dirty. Also do not expose it to ultra-violet rays when keeping it instorage. (Greater care should be used than when handling a CD disc.) CD-RW74 can be used repeatedly but use a number of 20 times as a rough standard for the limit. If the CD-R is a self-record/playback type, it can be reuse

44、d (for additional recording) unless it is finalized.(Nothing can be recorded additionally if finalized.)The CD-R disc which has not been finalized cannot be played back on a general type CD player. To play back the CD-RW, an applicable type CD player must be used.CDR-S1000CDR-S10009Check the power s
