P/No: MFL47342622

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

Precautions to avoid possible exposure to excessive microwave energy.

Precautions

When heating liquids, e.g. soups, sauces and beverages in your microwave
oven, delayed eruptive boiling 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(especially the contents of feeding bottles and baby food jars) 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.

Please ensure cooking times are correctly set as

over cooking may result in the FOOD catching fire

and subsequent damage to your oven.

How the Microwave Oven Works

3

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.

Place the oven in the level location of your choice with
more than 85cm height but make sure there is at least

30cm of space on the top and 10cm at the rear for proper
ventilation. The front of the oven should be at least 8cm from the
edge of the surface to prevent tipping.
An exhaust outlet is located on top or side of the oven. Blocking
the outlet can damage the oven.

Unpacking &

Installing

Unpack your oven and place it on a flat level
surface.
