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 any service
required should be performed by an authorized
YAMAHA Retailer or the appointed service
representative.
IMPORTANT: The presentation or sale of this manual to any
individual or firm does not constitute authorization,
certification or recognition of any applicable
technical capabilities, or establish a principle-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
specifications 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 buss in the unit (heavy gauge black
wires connect to this buss).
IMPORTANT: Turn the unit OFF during disassembly and part
replacement. Recheck all work before you apply
power to the unit.

cabinet.
a. Apply the block tothe rear panel so as to avoid damage
to the Terminal of the rear panel.
b. Use the screwdriver inserted in the gap between the
front grille and the cabinet (bottom side first), push up
the front grille. (Fig. 1)
c. Remove the front grille by lifting it up. (Fig. 1)
2. Remove of Speaker
a. Remove 4 screws (1) in Fig. 2, and remove the
speaker.
b. Remove the cable cord.
