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,

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

WARNING: Static discharges can destroy expensive components. Discharge any static electricity your body
