It has been assumed that basic service procedures inherent to the industry, and more specifi cally YAMAHA Products, are already known and 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 personal injury, destruction of expensive components, and failure of the product to perform as specifi ed. For these reasons, we advise all YAMAHA product owners that any service required should be performed by an authorized YAMAHA Retailer or the appointed service representative. IMPORTANT: The presentation or sale of this manual to any individual or fi rm does not constitute authorization, certifi cation or recognition 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, and service departments of YAMAHA are continually striving to improve YAMAHA products. Modifications are, therefore, inevitable and specifi cations are subject to change without notice or obligation to retrofi t. Should any discrepancy 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 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.

Note: When the following parts are replaced, the destination MUST be written to the back-up IC (EEPROM: IC222 on DIGITAL P.C.B.) to have proper operation. (For details, refer to No. 22 SOFT SWITCH menu of the self-diagnostic function.) DIGITAL P.C.B. EEPROM: IC222 on DIGITAL P.C.B. When the power amplifier IC (IC 1 or IC 2 on MAIN P.C.B.) requires to be replaced, be sure to refer to “POWER AMPLIFIER IC REPLACEMENT” before its replacement.

DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON WHATSOEVER! Avoid 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. 1. Critical Components Information Components having special characteristics are marked and must be replaced with parts having specifications equal to those originally installed. 2. Leakage Current Measurement (For 120V Models Only) When service has been completed, it is imperative to verify that all exposed conductive surfaces are properly insulated from supply circuits. Meter impedance should be equivalent to 1500 ohms shunted by 0.15 F. All of the P.C.B.s installed in this unit and solder joints are soldered using the lead free solder. Among some types of lead free solder currently available, it is recommended to use one of the following types for the repair work. Sn + Ag + Cu (tin + silver + copper) Sn + Cu (tin + copper) Sn + Zn + Bi (tin + zinc + bismuth) Caution: As the melting point temperature of the lead free solder is about 30C to 40C (50F to 70F) higher than that of the lead solder, be sure to use a soldering iron suitable to each solder. TO SERVICE PERSONNEL Leakage current must not exceed 0.5mA. Be sure to test for leakage with the AC plug in both polarities. WARNING: CHEMICAL CONTENT NOTICE! About lead free solder For U model “CAUTION” “F1501: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 6A, 125V FUSE.” For C model CAUTION F1501: REPLACE WITH SAME TYPE 6A, 125V FUSE. ATTENTION F1501: UTILISER UN FUSIBLE DE RECHANGE DE MME TYPE DE 6A, 125V.
