■ 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 ohms shunted
by 0.15 μF.

WALL

OUTLET

• Leakage current must not exceed 0.5mA.

• Be sure to test for leakage with the AC plug in both polarities.

WARNING: CHEMICAL CONTENT NOTICE!

This product contains chemicals known to the State of California to cause cancer, 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

About lead free solder /

All of the P.C.B.s installed in this unit and solder joints are
soldered using the lead free solder.

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:

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.

無鉛ハンダについて

本機に搭載されているすべての基板およびハンダ付けに
よる接合部は無鉛ハンダでハンダ付けされています。

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：

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
