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.

P.O.Box 1, Hamamatsu, Japan

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.

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：

① 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。

② 鉛入りハンダを使わざるを得ない場合は、あらかじめ交

換する部品端子部やその周辺部の無鉛ハンダをすべて取

り除くか、あるいは無鉛ハンダと鉛入りハンダが十分に

溶けた状態となるようにハンダ付けしてください。

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:

1. 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.

2. If lead solder must be used, be sure to remove lead free

solder from each terminal section of the parts to be

replaced and from the area around it completely before

soldering, or make sure that the lead free solder and

lead solder melt together fully.

The P.C.B.s installed in this unit are soldered using the

following solder.

本機に搭載されている基板のハンダ付けに使用されている

ハンダは下記の通りです。

“CAUTION”

“F501: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 5A, 125V FUSE.”

CAUTION

F501: REPLACE WITH SAME TYPE 5A, 125V FUSE.

ATTENTION

F501: UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE 5A, 125V.

・

やわらかい布等を敷いてその上で作業を行ってください。

・フロントグリル等で怪我をする恐れがあります。十分

注意してください。

・ネジを閉め忘れると、エアー漏れをすることがあります。

■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

・この製品の内部には高電圧部分があり危険です。修理の

際は、絶縁性の手袋を使用するなどの安全対策を行って

ください。

・ INPUT（1）P.C.B.のC523には電源をOFFにした後も電

荷が残り、高電圧が維持されており危険です。

修理作業前に放電用抵抗（5kΩ/10W）をC523の端子間

に接続して放電してください。

（放電用抵抗の接続箇所はP.52PRINTED CIRCUIT

BOARD［INPUT（1）P.C.B.］およびP.67SCHEMATIC

DIAGRAM［INPUT2/2］に記載しています。）

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 p.52

“PRINTED CIRCUIT BOARD [INPUT (1) P.C.B.]” and p.67

“SCHEMATIC DIAGRAM [INPUT 2/2]”)

When checking the P.C.B. :

•The Shield Unit removed from the unit does not work

because its grounding is loose. Be sure to connect the

ground of the Shield Unit to the chassis or GND with a

lead wire or the like. (Fig. A)

•Reconnect all cables (connectors) that have been

disconnected.

•When connecting the cable, use care for the polarity.
