It has been assumed that 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

4、 may result in per- sonal injury, destruction of expensive components and failure of the product to perform as specified. For these reasons, we advise all Yamaha product owners that all service required should be performed by an authorized Yamaha Retailer or the appointed service representative. IMP

5、ORTANT :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 of any form. The data provided is belived to be accurate and applicable to t

6、he unit(s) indicated on the cover. The research engineering, and service departments of Yamaha are continually striving to improve Yamaha products. Modifications are, therefore, inevitable and changes in specification are subject to change without notice or obligation to retrofit. Should any discrep

7、ancy appear to exist, please contact the distributors Service Division. WARNING :Static discharges can destroy expensive components. Discharge any static electricity your body may have accumulated by grounding yourself to the ground bus in the unit (heavy gauge black wires connect to this bus.) IMPO

8、RTANT :Turn the unit OFF during disassembly and parts replacement. Recheck all work before you apply power to 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 (Where applicable) compon

9、ents may also contain traces of chemicals found by the California Health and Welfare 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 FOR ANY REASON WHAT SO EVER! Avoid

10、 prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose eyes to solder/flux vapor! If you come in contact with solder or components located inside the enclosure of this product, wash your hands before handling food. WARNING Components having

11、 special characteristics are marked and must be replaced with parts having specification equal to those originally installed. LITHIUM BATTERY HANDLING This product uses a lithium battery for memory back-up. WARNING :Lithium batteries are dangerous because they can be exploded by improper handling. O

12、bserve 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 batte

13、ry 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. ADV
