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 the users,
and have therefore not been restated.
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 service
departments of Yamaha are continually striving to improve Yamaha products. Modifications are, therefore, inevitable and changes in
specification are subject to change without notice or obligation to retrofit. Should any discrepancy appear to exist, please contact the
distributor’s Service Division.
WARNING :Static discharges can destroy expensive components. Discharge any static electricity your body may have accumulated
by grounding yourself to the ground bus in the unit (heavy gauge black wires connect to this bus.)
IMPORTANT :Turn the unit OFF during disassembly and parts replacement. Recheck all work before you apply power to the unit.
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.
