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.

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 REA-
SON WHATSOEVER!
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.

■TO SERVICE PERSONNEL
1. Critical Components Information
Components having special characteristics are marked s
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 0.15µF.
●Leakage current must not exceed 0.5mA.
●Be sure to test for leakage with the AC plug in both polarities.
“CAUTION”
“F501: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 4A, 125V FUSE.”
CAUTION
F501: REPLACE WITH SAME TYPE 4A, 125V FUSE.
ATTENTION
F501: UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE 4A, 125V.
本機に搭載されているすべての基板は無鉛ハンダでハンダ
付けされています。
無鉛ハンダにはいくつかの種類がありますが、修理時には
下記のような無鉛ハンダの使用を推奨します。
・Sn+Ag+Cu（錫+銀+銅）
・Sn+Cu（錫+銅）
・Sn+Zn+Bi（錫+亜鉛+ビスマス）
注意：
無鉛ハンダの融点温度は通常の鉛入りハンダに比べ30
〜40℃程度高くなっていますので、それぞれのハンダ
に合ったハンダごてをご使用ください。
All of the P.C.B.s installed in this unit 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.

分解・組立時の注意：
■DISASSEMBLY PROCEDURES / 分解手順
(Remove parts in the order as numbered.)
Cautions for disassembly and reassembly :
• Disconnect the power cable from the AC outlet.
• Spread soft cloth or the like and perform the work on it.
• Use full care as you may be injured by the front grille
or other part.
• All screws must be tightened securely to prevent air
leakage. Check the number of screws and their
positions when installing them.
• When installing parts, be careful not to have anything
such as cables caught between other parts.
• Make sure that all the removed driver (tweeter) parts
are reinstalled at specified positions.

■SERVICE PRECAUTIONS / サービス時の注意事項
安全対策
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 C523 on the INPUT (1) P.C.B. is 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, perform discharge by
connecting a discharge resistor (5 k-ohms/10 W) between
C523 terminals.
(For the discharge resistor connection points, refer to page
49 “PRINTED CIRCUIT BOARD [INPUT (1) P.C.B.]” and
page 60 “SCHEMATIC DIAGRAM [INPUT 2/2]”)
