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 ohm
shunted by 0.15

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 + 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。
