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 REA-
SON WHAT SO EVER!
Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose
eyes to solder/flux vapor!

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
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.
