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 per-
sonal 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, certifica-
tion 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.
RDX-E600はRX-E600、NX-E400及びDVD-E600で構成されています。

■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 ohm
shunted by 0.15µF.

WARNING: CHEMICAL CONTENT NOTICE!
The solder used in the manufacturing process except soldering of the P.C.B. ass'y 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.
●Leakage current must not exceed 0.5mA.
●Be sure to test for leakage with the AC plug in both polarities.
“CAUTION”
“F232: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 3.15A,
125V FUSE.”
CAUTION
F232: REPLACE WITH SAME TYPE 3.15A, 125V FUSE.
ATTENTION
F232: UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE 3.15A, 125V.
About Lead Free Solder / 無鉛ハンダについて
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。
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.
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。

CAUTION : When executing Test mode No. 2 RAM CLEAR, be sure to write down the preset memory contents of the
tuner, using a table like the one shown below. Execution of RAM CLEAR will set the memory contents of the
tuner back to the factory preset state which means that all the memories preset by the user will be erased.
注意 : テストモード番号02のRAMCLEARを実行するときは、チューナーのプリセットメモリー内容を、下表のよう
なものにメモしておいてください。（RAMCLEARを実行すると、チューナーのメモリー内容がメーカープリセッ
ト状態になるため、ユーザーのプリセットメモリーがすべて消去されます。）テストモード終了後、再びチュー
ナーにして、メモを参照しユ−ザーメモリーを行ってください。

* Confirm that the idling current is 0.25mV — 15mV after 60 minutes.
* 60分後には、アイドリング電流が0.25mV〜15mVであることを確認する。
Note/ 対策
If the measured voltage exceeds 5mV, cut the lead wire of R308(L ch)
or R309(R ch) and then check again if each measured value satisfies the
rating.
電圧が5mVを越えている場合はR308（Lch）または、R309（R ch）のリード線

Note)
•If the idling current exceeds 5mV after a power amplifier
repair, check for a defective component before cutting the
resistor.
•If R308(L ch) or R309(R ch) have already been cut off and
idling current does not flow, reconnect R308(1k-ohms) or
R309(1k-ohms).
•Q261 and Q262 are transistors for temperature correction.
Apply silicone grease to the contact surface with the heat
sink.
