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, 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.
