■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 Model only).
When service has been completed, it is imperative that you
verify that all exposed conductive surfaces are properly insu-
lated from supply circuits.
●Meter impedance should be equivalent to 1500 ohm shunted by
0.15µF.
●Leakage current must not exceed 0.5mA.
●Be sure to test for leakage with the AC plug in both polarities.
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 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 handling
food.
