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.
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 prop-
erly insulated from supply circuits.
●
Meter impedance should be equivalent to 1500 ohms
shunted by 0.15
µ
F.
●
Leakage current must not exceed 0.5mA.
●
Be sure to test for leakage with the AC plug in both
polarities.

TO SERVICE PERSONNEL
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たハンダ
ごてをご使用ください。
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 + 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.

WARNING: Laser Safety
This product contains a laser beam component. This component may emit invisible, as well as visible radiation,
which may cause eye damage. To protect your eyes and skin from laser radiation, the following precautions must be
used during servicing of the unit.
1) When testing and/or repairing any component within the product, keep your eyes and skin more than 30 cm away from
the laser pick-up unit at all times. Do not stare at the laser beam at any time.
2) Do not attempt to readjust, disassemble or repair the laser pick-up, unless noted elsewhere in this manual.
3) CAUTION : Use of controls, adjustments or performance of procedures other than those specified herein may result in
hazardous radiation exposure.
