It has been assumedthat basic service procedures inherent to the industry, and more specifically Yamaha Products, are already known and under-stood 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 per-sonal injury, destruction of expensive components and failure of the product to perform as specified. Forthese reasons, we advise all Yamaha product owners that all service required should be performed by anauthorized Yamaha Retailer or the appointed service representative.IMPORTANT :This presentation or sale of this manual to any individual or firm does not constitute authorization certifi-cation, recognition of any applicable technical capabilities, or establish a principal-agent relationship ofany form.The data provided is belived 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 changes in specification are subject to change without notice or obligation to retrofit. Should any discrepancy appear toexist, please contact 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 bus in the unit (heavy gauge black wires connect tothis bus.)IMPORTANT :Turn the unit OFF during disassembly and parts replacement. Recheck all work before you apply powerto the unit.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 REASON WHATSO EVER!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.WARNINGComponents having special characteristics are marked and must be replaced with parts having specification equal to thoseoriginally installed.RadioFans.CN 收音机爱 好者资料库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 precautionmust be used during servicing of the unit.1) When testing and / or repairing any component within the product, keep your eyes and skin more than30cm away from the laser pick-up unit at all time. Do not stare the laser beam at any time.2) Do not attempt readjustment,disassemble and repair of the laser pick-up, unless noted elsewhere in thismanual.3) CAUTION - Use of controls or readjustments or performance of procedures other than those specifiedherein may result in hazardous radiation exposure.PROTECTION OF EYES FROM LASER BEAM DURING SERVICINGLaser Diode Properties* Material : GaAlAs* Wavelength : 783789 nm* Emission Duration : Continuous* Laser Output Power : Less than 44.6 WLaser output is measured at a distance of 20cm from the object lens on the optical pick-up head.(Note)When checking the laser diode emission, keep your eyes more than 30 cm away from the objective lens.
