Precautions

Precautions to avoid possible exposure to excessive microwave energy.

You cannot operate your oven with the door open due to the safety interlocks
built into the door mechanism. These safety interlocks automatically switch off
any cooking activity when the door is opened; which in the case of a
microwave oven could result in harmful exposure to microwave energy.

It is important not to tamper with the safety interlocks.

Do not place any object between the oven front face and the door or allow
food or cleaner residue to accumulate on sealing surfaces.

Do not operate your oven if it is damaged. It is particularly important that the
oven door closes properly and that there is no damage to the: (1) door(bent),
(2) hinges and latches (broken or loosened), (3) door seals and sealing
surfaces.

Your oven should not be adjusted or repaired by anyone except qualified
service personnel.

Warning

Please ensure cooking times are correctly set as

over cooking may result in the FOOD catching fire

and subsequent damage to your oven.

When heating liquids, e.g. soups, sauces and beverages in your microwave
oven, overheating the liquid beyond boiling point can occur without
evidence of bubbling. This could result in a sudden boil over of the hot
liquid. To prevent this possibility the following steps should be taken:

1 Avoid using straight sided containers with narrow necks.

2 Do not overheat.

3 Stir the liquid before placing the container in the oven and again halfway

through the heating time.

4 After heating, allow to stand in the oven for a short time, stir or shake

them again carefully and check the temperature of them before
consumption to avoid burns (especially, contents of feeding bottles and
baby food jars).
Be careful when handling the container.

Warning

Always allow food to stand after being cooked by

microwaves and check the temperature of them

before consumption. Especially contents of feeding

bottles and baby food jars.

How the Microwave Oven Works

Microwaves are a form of energy similar to radio and television waves and
ordinary daylight. Normally, microwaves spread outwards as they travel
through the atmosphere and disappear without effect. Microwave ovens,
however, have a magnetron which is designed to make use of the energy in
microwaves. Electricity, supplied to the magnetron tube, is used to created
microwave energy.

These microwaves enter the cooking area through openings inside the oven. A
turntable or tray is located at the bottom of the oven. Microwaves cannot pass
through metal walls of the oven, but they can penetrate such materials as
glass, porcelain and paper, the materials out of which microwave-safe
cooking dishes are constructed.

Microwaves do not heat cookware, though cooking vessels will eventually get
hot from the heat generated by the food.

A very safe appliance

Your microwave oven is one of the safest of all home

appliances. When the door is opened, the oven

automatically stops producing microwaves. Microwave

energy is converted completely to heat when it enters

food, leaving no “left over” energy to harm you when

you eat your food.
