destruction of expensive components, and failure of the product to perform as specifi ed. 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 fi rm does not constitute authorization, certifi cation 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

specifi cations are subject to change without notice or obligation to retrofi t. 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
