How a Microwave Oven Works

Microwaves are high-frequency electromagnetic waves; the energy released enables food to be cooked or reheated without changing either the form or the colour.

You can use your microwave oven to:

•Defrost

•Cook

•Reheat

Cooking Principle

1.The microwaves generated by the magnetron are distributed uniformly as the food rotates on the turntable. The food is thus cooked evenly.

2.The microwaves are absorbed by the food up to a depth of about 1 inch (2.5 cm). Cooking then

continues as the heat is dissipated within the food.

3. Cooking times vary according to the recipient used and the properties of the food:

•Quantity and density

•Water content

•Initial temperature (refrigerated or not)

☛As the centre of the food is cooked by heat dissipation, cooking continues even when you have taken the food out of the oven. Standing times specified in recipes and in this booklet must therefore be respected to ensure:

•Even cooking of the food right to the centre

•The same temperature throughout the food

Checking that Your Oven is Operating Correctly

The following simple procedure enables you to check that your oven is working correctly at all times.

First, place a bowl of water on the turntable. Then, close the door.

Model :M1717N

1.Select the power level to maximum by turning COOKING

POWER CONTROL knob.

2. Select the time 4 to 5 minutes by turning the TIMER knob. The water should then be boiling.

✉The oven must be plugged into an appropriate wall socket. The turntable must be in position in the oven. If a power level other than the maximum is used, the water takes longer to boil.
