TO SERVICE PERSONNEL
1. Critical Components Information
Components having special characteristics are marked
Z
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

Be sure to test for leakage with the AC plug in both
polarities.
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 REASON
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.
About lead-free solder /
無鉛ハンダについて

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 + 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。
