WHAT ARE MICROWAVES?

Microwaves are electromagnetic waves, similar to
radio and TV-waves.
Microwaves are generated by a magnetron inside
the microwave oven and cause the water
molecules in food to vibrate. This causes friction,
which in turn generates heat, which then thaws,
heats or cooks your food.
The secret of the shorter cooking time is that
microwaves enter your food from all sides. Energy
is used optimally. In comparison with a stove, the
energy used on a burner reaches the food only
through the hot plate and the cooking pot. This
"detour" loses a lot of energy.
FEATURES OF MICROWAVES
Microwaves penetrate all non-metal objects, like

WHAT YOUR NEW COMBI-MICROWAVE OVEN CAN DO

MICROWAVE OPERATION
By using microwaves in your new combi-
microwave oven, you can quickly heat individual
servings or drinks, or melt butter or chocolate in a
very short time. The microwave is also
exceptionally well suited for thawing foods. In
many cases it is beneficial to combine microwaves
with hot air or the grill.
This enables you to cook and brown your foods in
a short time. Compared to conventional roasting,
the cooking time is usually much shorter.
COMBI OPERATION (MICROWAVE
WITH HOT AIR OR GRILL)
By joining two different modes of operation, the
benefits of your microwave oven will improve
functionality.
You may choose between
• Microwave + Hot air (ideal for roasts, poultry,
casseroles, pizza, bread and cakes) and
• Microwave + Grill (ideal for quick-fried, roasts,
poultry, chicken drum sticks, shish kabobs,
cheese toast and "au gratin").
By using the combi operation you can cook and
brown foods simultaneously.

glass, porcelain, ceramics, plastic, wood or paper.
This is why microwaves do not heat these
materials. Cookware is heated only indirectly
through the heat of the food.
Foods absorb microwaves and heat up.
Microwaves cannot penetrate material made of
metal because metal reflects microwaves.
Therefore, objects made of metal are not usually
suitable for use in a microwave. There are some
exceptions to this rule, where you may use this
exact attribute. You might cover certain areas of
some foods with aluminum foil during thawing or
cooking. This way you can avoid areas that are
too warm or too hot or overcooked. Please
remember the following notes.
One benefit is that the hot air or the heat of the
grill element will quickly seal the pores of the
food's outer surface. Microwaves ensure a short
cooking time. The food will stay moist on the
inside and be crunchy brown on the outside.
HOT AIR OPERATION
You can also use hot air without the microwaves.
The result will be just like in a conventional hot air
stove. Circulating air quickly heats the outer
surfaces of your food. Meat, for example, will stay
moist and your food will not dry out.
This sealing process ensures that your foods will
stay tasty and cook faster than regular stoves with
top- and bottom heating elements.
GRILL OPERATION
Your new microwave oven is equipped with a
quartz grill located on the ceiling of the cooking
chamber. Just like any conventional grill, it can be
used without the microwaves. You can quickly
brown or grill foods. This is especially suitable for
steaks, cutlets or gratinating foods.
