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 or firm does not constitute authorization, certifica-
tion 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
