IMPOR TANT 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 specifi\
cally Yamaha Products, are already known and under-
stood by the users, and have therefore not been restated.
WARNING :Failure to follow appropriate service and safety procedures when servici\
ng this product may result in per-
sonal injury, destruction of expensive components and failure of the pro\
duct to perform as specified. For
these reasons, we advise all Yamaha product owners that all service requ\
ired 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 certifi-
cation, recognition of any applicable technical capabilities, or establi\
sh 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 obl\
igation to retrofit. Should any discrepancy appear to
exist, please contact the distributorÕs 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 addi\
tion, other electrical/electronic and/or plastic (Where
applicable) components may also contain traces of chemicals found by th\
e California Health and Welfare Agency (and possibly
other entities) to cause cancer and/or birth defects or other reproduct\
ive 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 encl\
osure of this product, wash your hands before handling
food.
