Important information
} What are microwaves?
Microwaves are electromagnetic waves, similar to radio waves and TV waves. Their cooking
power is derived from causing the smallest components of the food, especially the fat and
water molecules, to vibrate, so that the molecules rub against each other. This friction
causes heat that is so powerful that the food is cooked in a very short time.
The microwaves are generated in the magnetron, the heart of any microwave appliance, a
high-frequency tube sending out waves. The microwaves are fed into the cooking space via
a metallic duct, and there they are distributed uniformly to the food to be cooked with the
aid of the turntable.
} What are the properties of microwaves?
Microwaves travel in a straight line though space. They pass unimpaired through materials
like glass, china, ceramics, plastics, and paper, and they can be received by food, i.e. they can
act directly onto the food. It is not necessary to heat the tableware first. Microwaves are
reflected by metal surfaces. This means that metal shields against microwaves.
} Are microwaves dangerous?
Microwaves are relatively long waves, as have been used for decades for medical heat
treatment. The microwaves are shielded from the environment by the metal housing, so that
they cannot leave the cooking space during cooking or when the door is opened. A double
safety system shuts o the microwaves immediately when the appliance is opened.
Changes to the food from microwaves with a damaging eect on health could not be found
through extensive scientific investigations and decades of observation. Just the opposite
- with correct operation, the microwave oven can oer a valuable contribution to healthier
nutrition. A microwave appliance is subject to a number of legal regulations and tests.
KOENIC microwave appliances are tested and checked by accredited test institutes.
} How is the microwave oven regulated?
As with other electrical equipment and hobs, you can select an operating time and dierent
power levels with the microwave oven. A timer or an electronic clock automatically turns the
appliance o when the set cooking time has elapsed.
In contrast to conventional cooking methods, the power and the time setting play a larger
role, as the microwaves heat the food directly. Thus, the selection of the correct power
setting and time is key for good cooking or thawing results.
