Plug the AC line cord of the appliance directly into a 120 V AC 60 Hz outlet and turn the AC power switch on. Any current measured must not exceed 0.5 mA.

Electrical components having such features are identified by marking with a > on the schematics and on the parts list in this Service Manual.

The use of a substitute replacement component which does not have the same safety characteristics as the PIO N EER recommended replacement one, shown in the parts list in this Service Manual, may create shock, fire, or other hazards.
