                                                  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 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 believed 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.

      DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY
      REASON WHAT SO EVER!
