■ 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.

“CAUTION”

“F1: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 1.6A, 125V FUSE.”

CAUTION

F1: REPLACE WITH SAME TYPE 1.6A, 125V FUSE.

ATTENTION

F1: UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE 1.6A, 125V.

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.

● 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.
