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, 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,
