I TO SERVICE PERSONNEL
1. Critical Components Information
Components having special characteristics are marked A
and must be replaced with parts having specifications equal to
those originally installed.
2. Leakage Current Measurement (For 120 V Model Only).
When service has been completed, it is imperative that you
verily that all exposed conductive surfaces are properly
insulated from supply circuits.
- Meter impedance should be equivalent to 1500 ohm shunted
by 0.15 uF.
- Leakage current must not exceed 0.5 mA.
- Be sure to test for leakage with the AC plug in both polarities.
- POLARIZATION
This product is equipped with a polarized altematlng current
line plug (a plug having one blade wider than the other ). This
