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
