WARNING: CHEMICAL CONTENT NOTICE!
The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (where
applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and possibly
other entities) to cause cancer and/or birth defects or other reproductive harm.
DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON
WHAT SO EVER!
Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose eyes
to solder/flux vapor!
If you come in contact with solder or components located inside the enclosure of this product, wash your hands before handling
food.
IMPORTANT NOTICE
This manual has been provided for the use of authorized Yamaha Retailers and their service personnel. It has been assumed that
basic service procedures inherent to the industry, and more specifically Yamaha Products, are already known and understood by

WARNING: 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 all service required should be performed by an authorized
Yamaha Retailer or the appointed service representative.
IMPORTANT: This presentation or sale of this manual to any individual or firm does not constitute authorization, certification,
recognition of any applicable technical capabilities, or establish a principal-agent relationship of any form.
The data provided is belived to be accurate and applicable to the unit(s) indicated on the cover. The research engineering, and
