POWER CONSUMPTION VERIFICATION
1. Plug Model 3600 AC Plug into AC Con-
trol Box outlet.
2. Set LINE Switch (AC Power Control
Box) to VARIABLE.
3. Observing Wattmeter, slowly rotate auto-
transformer control CW to 120 VAC.
If Wattmeter indicates more than 7 W at
any time, (or fails to indicate at all), shut
off AC power and refer to the Trouble
Analysis section.
