IMPORTANT NOTICE

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.
