HOW THE MICROWAVE/
CONVECTION OVEN WORKS
MICROWAVE COOKING
Using microwave energy only, food is cooked quickly
without altering its color or shape. The food is evenly
cooked on a rotating turntable as the microwaves are
produced by the magnetron. Power Control can be
adjusted in 10 steps, enabling the various kinds of foods
to cook at most desirable cooking power for the best
results.
CONVECTION COOKING
This is a way of cooking with hot air from the convec-tion
heater on the back side of the unit. This method allows
food to be browned evenly without losing any of the
juices. Heated air is circulated in the oven by a fan to
enable the heating and cooking of food. Since hot air
remains in the oven as it circulates, cooking is very
efficient. The temperature inside the oven can be con-
trolled according to the type of food being cooked.
COMBINATION COOKING
With microwave energy and hot air, this solid-state
control can cook alternately according to the cycles
programmed between microwave and hot air to pro-vide
efficient cooking fully utilizing the advantages of
two functions. Convection rack is also used in Combi-
nation Cooking.
