LOWER POWER (L) controls the lower ceramic heater.
Select a higher setting for thick or dense foods that
may not cook quickly in the center. Select a lower
setting for thin foods, such as cookies.

MICROWAVE (M) controls operation of the
microwave. Select a higher setting to shorten
cooking time for dense or heavy food, such as
whole chicken. Select a lower setting for delicate
foods, such as breads or foods requiring longer
times.

CONVECTION (C) controls the heat output of the
convection system. Select a lower setting for more
delicate foods that cook at lower temperatures.
Select a higher setting (6 or above) for more robust
foods that cook at temperatures above 350°F.

The programming on the smart board which
controls the upper halogen lamps (pair) and the
lower ceramic heater, as well as the high voltage/
magnetron circuits, operates on a duty cycle of
32 seconds. This means the power level you select
for each component controls the percentage of
ON time during each 32-second period of time. For
example, when the oven is set on power level 10,
both the inner and outer halogen heaters will stay
on 100% of the time. On power levels less than 10,
both heaters will cycle together.
In the following example, the upper halogen lamps
would cycle for 80% of each 32-second period,
the lower ceramic heater would cycle at 50% of
each 32-second period, and the microwave high
voltage circuit would be energized for 30% of each
32-second period.

Notes:
:
1. Convection element not ON.
2. Reaches temperature and then cycles at
temperature for remainder of programmed time.
3. Reaches temperature and then cycles at 350°F
for remainder of programmed time.
