Speedcook Overview
Upper Heaters
The upper heating assembly consists of two 1200-
watt halogen heaters. The halogen heaters provide
radiant heat, which browns the outside of the food
while sealing in moisture and fl avor. These heaters
are operated by the control board based on power
levels and duty cycle, and only operate in the
Speedcook mode. However, during any cook mode
the inner heater can be energized for 4 seconds by
pushing the

will illuminate the oven cavity long enough for the
customer to see the contents inside the oven.
Lower Heater
The lower heater is a 500-watt ceramic heater.
It operates in Speedcook, oven/bake, and warm
modes. The lower heater assists in browning foods
on the bottom.
Convection System
The 1500-watt convection system consists of a
convection heater and fan that operate when
using convection bake, broil, or toast, and assists in
heating the oven when using Speedcook.
Microwave Energy
When cooking in Microwave mode, always
Caution:
use the glass tray.
The Advantium 240 provides 950 watts of
microwave power, which is delivered directly
into the oven cavity to work independently, or in
conjunction with other cooking cycles. As the food
rotates on the oven turntable, microwave energy is
evenly distributed to all portions of the food.
Sensor Cooking
Advantium's microwave mode features sensor
cooking, which automatically selects cook times
and power levels. A humidity sensor detects the
increasing humidity released during cooking, senses
when the food is done, and shuts the oven off at the
appropriate time. Sensor cooking is not available for
5 minutes immediately following Speedcook.
pad on the control panel. This
Power Levels
Advantium uses power from high-intensity halogen
lamps, a ceramic heater, microwave energy, as
well as convection heating to simultaneously cook
foods evenly and quickly (average of one-fourth the
time of a conventional oven) to seal in moisture and
fl avor.
Power levels are selected with the selector dial and
can be adjusted before cooking or during cooking.
When using preset menu foods, the power levels
are already selected. However, power levels can be
adjusted when cooking both preset menu food and
when manual cooking.
Power levels from 0 to 10 can be selected and
adjusted independently for the upper halogen
lamps (pair), lower ceramic heater (single),
microwave energy, and convection heating. When
selecting an upper halogen lamp power level, the
power level can only be selected for the pair. You
cannot select power levels for the inner and outer
independently.
The power levels control the percentage of ON time
for the upper halogen lamp pair, the lower ceramic
heater, and microwave high voltage circuit. During
Speedcook, the operation of the convection heater
is based on temperature. The convection heater will
cycle on and off if needed, and the convection fan
will operate continuously throughout Speedcook.
UPPER POWER (U) controls the upper halogen
heaters. Select a higher setting for such foods as
pizza and baked goods. Select a lower setting for
foods, such as casseroles, meats, and fi sh.
