IMPORTANT  NOTICE

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 of 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.
