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.WARNING: THIS APPARATUS MUST BE EARTHEDIMPORTANTTHE WIRES IN THIS MAINS LEAD ARE COLOURED IN ACCORDANCE WITH THE FOLLOWING CODE: GREEN-AND-YELLOW : EARTH BLUE : NEUTRAL BROWN : LIVEAs the colours of the wires in the mains lead of this apparatus may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows:The wire which is coloured GREEN and YELLOW must be connected to the terminal in the plug which is marked by the letter E or by the safety earth symbol or coloured GREEN and YELLOW.The wire which is coloured BLUE must be connected to the terminal which is marked with the letter N or coloured BLACK.The wire which is coloured BROWN must be connected to the terminal which is marked with the letter L or coloured RED.* This applies only to products distributed by YAMAHA KEMBLE MUSIC (U.K.) LTD.RadioFans.CN 收音机爱 好者资料库02R963LITHIUM BATTERY HANDLINGThis product uses a lithium battery for memory back-up.WARNING :Lithium batteries are dangerous because they can be exploded by improper handling. Observe the following pre-cautions when handling or replacing lithium batteries.Leave lithium battery replacement to qualified service personnel.Always replace with batteries of the same type.When installing on the PC board by soldering, solder using the connection terminals provided on the battery cells.Never solder directly to the cells. Perform the soldering as quickly as possible.Never reverse the battery polarities when installing.Do not short the batteries.Do not attempt to recharge these batteries.Do not disasemble the batteries.Never heat batteries or throw them into fire.ADVARSEL!Lithiumbatteri-Eksplosionsfare ved fejlagtig handtering. Udskiftning ma kun ske med batteri af samme fabrikat og type. lever det brugtebatteri tilbage til leverandren.VARNINGExplosionsfara vid felaktigt batteribyte.Anvand samma batterityp eller en ekvivalent typ som rekommenderas av apparattillverkaren.Kassera anvant batteri enligt fabrikantens instruktion.VAROITUSParisto voi rajahtaa, jos se on virheellisesti asennettu.Vaihda paristo ainoastaan laitevalmistajan suosittelemaan tyyppiiin.Havita kaytetty paristo valmistajan ohjeiden mukaisesti.The following information complies with Dutch official Gazette 1995. 45; ESSENTIALS OF ORDER ON THE COLLECTION OF BATTERIES. Please refer to the diassembly procedure for the removal of Back-up Battery.
