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 understood by the users, and have therefore not been restated.
WARNING:
IMPORTANT:
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
specifi cations are subject to change without notice or obligation to retrofi t. Should any discrepancy appear to exist, please contact the

WARNING:
IMPORTANT:
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 specifi ed. 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.
The presentation or sale of this manual to any individual or fi rm does not constitute authorization, certifi cation or
recognition of any applicable technical capabilities, or establish a principle-agent relationship of any form.
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).
Turn the unit OFF during disassembly and part replacement. Recheck all work before you apply power to the unit.

■ TO SERVICE PERSONNEL
1. Critical Components Information
Components having special characteristics are marked ⚠ and
must be replaced with parts having specifications equal to those
originally installed.
2. Leakage Current Measurement (For 120V Models Only)
When service has been completed, it is imperative to verify
that all exposed conductive surfaces are properly insulated
from supply circuits.
• Meter impedance should be equivalent to 1500 ohms shunted
by 0.15 μF.

About lead free solder /
All of the P.C.B.s installed in this unit and solder joints are
soldered using the lead free solder.
Among some types of lead free solder currently available,
it is recommended to use one of the following types for
the repair work.
• Sn + Ag + Cu (tin + silver + copper)
• Sn + Cu (tin + copper)
• Sn + Zn + Bi (tin + zinc + bismuth)
Caution:
As the melting point temperature of the lead free solder
is about 30°C to 40°C (50°F to 70°F) higher than that of
the lead solder, be sure to use a soldering iron suitable
to each solder.

■ SERVICE PRECAUTIONS /
サービス時の注意事項
Safety measures
• Some internal parts in this product contain high voltages
and are dangerous.
Be sure to take safety measures during servicing, such
as wearing insulating gloves.
• Note that the capacitors indicated below are dangerous
even after the power is turned off because an electric
charge remains and a high voltage continues to exist
there.
Before starting any repair work, connect a discharging
resistor (5 k-ohms/10 W) to the terminals of each
capacitor indicated below to discharge electricity.
The time required for discharging is about 30 seconds
per each.
