This manual has been provided for the use of authorized YAMAHA Retailers and their service personnel.

It has been assumed that basic service procedures inherent to the industry, and more specifically 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 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.

IMPORTANT:

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.

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 specifications are subject to change without notice or obligation to retrofit. Should any discrepancy appear to

exist, please contact the distributor's 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.
