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 of 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,
