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 specified. 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.

The presentation or sale of this manual to any individual or firm does not constitute authorization, certification or

recognition of any applicable technical capabilities, or establish a principle-agent relationship of any form.

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).

Turn the unit OFF during disassembly and part replacement. Recheck all work before you apply power to the unit.
