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).
