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 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.
IMPORTANT NOTICE FOR THE UNITED KINGDOM
Connecting the Plug and Cord
IMPORTANT. The wires in this main lead are coloured in
accordance with the following code:
BLUE: NEUTRAL
BROWN: LIVE
As the colours of the wires in the main lead of this apparatus may not
correspond with the coloured markings identifying the terminals in
your plug, proceed as follows:
The BLUE wire must be connected to the terminal that is marked with
the letter N (or coloured BLACK).
The BROWN wire must be connected to the terminal that is marked
with the letter L (or coloured RED).
Be certain that neither core is connected to the earth terminal of the
three pin plug.
WARNING
Components having special characteristics are marked and must be replaced with parts having specification equal to those
originally installed.
