The data provided is believed to be accurate and applicable to the unit(s) indicated on the cover. The research, engineer

6、ing, and service departments of YAMAHA are continually striving to improve YAMAHA products. Modifications are, therefore, inevitable and specifications are subject to change without notice or obligation to retrofit. Should any discrepancy appear to exist, please contact the distributors Service Divi

7、sion. 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.

8、Recheck all work before you apply power to the unit. IMPORTANT NOTICE DSP-AX1/RX-V1 SERVICE MANUAL DSP-AX1/RX-V1 DSP-AX1/RX-V1 I TO SERVICE PERSONNEL 1. Critical Components Information. Components having special characteristics are marked Z and must be replaced with parts having specifications equal
