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
Your oven should not be adjusted or repaired by anyone except qualified
service personnel.
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, 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.
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.
Unpacking &
By following the basic steps on these two pages you will be able to quickly check that your oven is operating
correctly. Please pay particular attention to the guidance on where to install your oven. W hen unpacking your
oven make sure you remove all accessories and packing. Check to make sure that your oven has not been
damaged during delivery.
Unpack your oven and place it on a flat level
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.

ceramic containers which have metallic (e.g. gold or silver) inlays. Always
remove metal twist ties. Metal objects in the oven may arc, which can
cause serious damage.
7 Do not operate the oven with a kitchen towel, a napkin or any other
obstruction between the door and the front edges of the oven, which may
cause microwave energy leakage.
8 Do not use recycled paper products since they may contain impurities
which may cause sparks and/or fires when used in cooking.
9 Do not rinse the turntable by placing it in water just after cooking. This
may cause breakage or damage.
10 Small amounts of food require shorter cooking or heating time. If normal
times are allowed they may overheat and burn.
11 Be certain to place the oven so the front of the door is 8 cm or more
behind the edge of the surface on which it is placed, to avoid accidental
tipping of the appliance.

Food characteristics&
Microwave cooking
Keeping an eye on things
The recipes in the book have been formulated with great care, but your success in
preparing them depends on how much attention you pay to the food as it cooks.
Always watch your food while it cooks. Your microwave oven is equipped with a
light that turns on automatically when the oven is in operation so that you can see
inside and check the progress of your food. Directions given in recipes to elevate,
stir, and the like should be thought of as the minimum steps recommended. If the
food seems to be cooking unevenly, simply make the necessary adjustments you think
appropriate to correct the problem.
Factors affecting microwave cooking times
Many factors affect cooking times. The temperature of ingredients used in a recipe
makes a big difference in cooking times. For example, a cake made with ice-cold
butter, milk, and eggs will take considerably longer to bake than one made with
ingredients that are at room temperature. All of the recipes in this book give a range
of cooking times. In general, you will find that the food remains under-cooked at the
lower end of the time range, and you may sometimes want to cook your food beyond
the maximum time given, according to personal preference. The governing
philosophy of this book is that it is best for a recipe to be conservative in giving
cooking times. While overcooked food is ruined for good. Some of the recipes,
particularly those for bread, cake, and custards, recommend that food be removed
from the oven when they are slightly undercooked. This is not a mistake. When
allowed to stand, usually covered, these foods will continue to cook outside of the
oven as the heat trapped within the outer portions of the food gradually travels
inward. If the food is left in the oven until it is cooked all the way through, the outer
portions will become overcooked or even burnt. You will become increasingly skilful
in estimating both cooking and standing times for various foods.
Density of food
Light, porous food such as cakes and breads cook more quickly than heavy, dense
foods such as roasts and casseroles. You must take care when microwaving porous
food that the outer edges do not become dry and brittle.
Height of food
The upper portion of tall food, particularly roasts, will cook more quickly than the
lower portion. Therefore, it is wise to turn tall food during cooking, sometimes several
Moisture content of food
Since the heat generated from microwaves tends to evaporate moisture, relatively dry food
such as roasts and some vegetables should either be sprinkled with water prior to cooking
or covered to retain moisture.
Bone and fat content of food
Bones conduct heat and fat cooks more quickly than meat. Care must be taken when
cooking bony or fatty cuts of meat that they do not cook unevenly and do not become
Quantity of food
The number of microwaves in your oven remains constant regardless of how much food is
being cooked. Therefore, the more food you place in the oven, the longer the cooking time.
Remember to decrease cooking times by at least one third when halving a recipe.
Shape of food
Microwaves penetrate only about 2.cm into food, the interior portion of thick foods are
cooked as the heat generated on the outside travels inward. Only the outer edge of food in
cooked by microwave energy; the rest is cooked by conduction. The worst possible shape
for a food that is to be microwaved is a thick square. The corners will burn long before the
centre is even warm . Round thin foods and ring shaped foods cook successfully in the
A cover traps heat and steam which causes food to cook more quickly. Use a lid or
microwave cling film with a corner folded back to prevent splitting.
Meats and poultry that are cooked fifteen minutes or longer will brown lightly in their own
fat. Food that are cooked for a shorter period of time may be brushed with a browning
sauce such as worcestershire sauce, soy sauce or barbecue sauce to achieve an appetizing
colour. Since relatively small amounts of browning sauces are added to food the original
flavour of the recipe is not altered.
Covering with greaseproof paper
Greaseproofing effectively prevents spattering and helps food retain some heat. But
because it makes a looser cover than a lid or clingfilm, it allows the food to dry out slightly.
Arranging and spacing
Individual foods such as baked potatoes, small cakes and hors d’oeuvres will heat more
evenly if placed in the oven an equal distance apart, preferably in a circular pattern. Never
stack foods on top of one another.
Food characteristics &
Microwave cooking.
Stirring is one of the most important of all microwaving techniques. In conventional cooking,
food is stirred for the purpose of blending. Microwaved food, however, is stirred in order to
spread and redistribute heat. Always stir from the outside towards the centre as the outside
of the food heats first.
Turning over
Large, tall foods such as roasts and whole chickens should be turned so that the top and
bottom will cook evenly. It is also a good idea to turn cut up chicken and chops.
Placing thicker portions facing outwards
Since microwaves are attracted to the outside portion of food, it makes sense to place
thicker portions of meat, poultry and fish to the outer edge of the baking dish. This way,
thicker portions will receive the most microwave energy and the food will cook evenly.
Strips of aluminium foil (which block microwaves) can be placed over the corners or edges
of square and rectangular foods to prevent those portions from overcooking. Never use too
much foil and make sure the foil is secured to the dish or it may cause ‘arcing’ in the oven.
Thick or dense foods can be elevated so that microwaves can be absorbed by the underside
and centre of the foods.
Foods enclosed in a shell, skin or membrane are likely to burst in the oven unless they are
pierced prior to cooking. Such foods include yolks and whites of eggs, clams and oysters
and whole vegetables and fruits.
Testing if cooked
Food cooks so quickly in a microwave oven, it is necessary to test it frequently. Some foods
are left in the microwave until completely cooked, but most foods, including meats and
poultry, are removed from the oven while still slightly undercooked and allowed to finish
cooking during standing time. The internal temperature of foods will rise between 50F (30C)
and 150F (80C) during standing time.
Standing time
Foods are often allowed to stand for 3 to 10 minutes after being removed from the
microwave oven. Usually the foods are covered during standing time to retain heat unless
they are supposed to be dry in texture (some cakes and biscuits, for example). Standing
allows foods to finish cooking and also helps flavour blend and develop.
To Clean Your Oven
1 Keep the inside of the oven clean
Food spatters or spilled liquids stick to oven walls and between seal and door
surface. It is best to wipe up spillovers with a damp cloth right away. Crumbs and
spillovers will absorb microwave energy and lengthen cooking times. Use a damp
cloth to wipe out crumbs that fall between the door and the frame. It is important to
keep this area clean to assure a tight seal. Remove greasy spatters with a soapy cloth
then rinse and dry. Do not use harsh detergent or abrasive cleaners. The glass tray
can be washed by hand or in the dishwasher.
2 Keep the outside of the oven clean
Clean the outside of your oven with soap and water then with clean water and dry
with a soft cloth or paper towel. To prevent damage to the operating parts inside the
oven, the water should not be allowed to seep into the ventilation openings. To clean
control panel, open the door to prevent oven from accidentally starting, and wipe a
damp cloth followed immediately by a dry cloth. Press STOP/CLEAR after cleaning.
3 If steam accumulates inside or around the outside of the oven door, wipe the panels
with a soft cloth. This may occur when the microwave oven is operated under high
humidity conditions and in no way indicates a malfunction of the unit.
4 The door and door seals should be kept clean. Use only warm, soapy water, rinse
then dry thoroughly.
Metal parts will be easier to maintain if wiped frequently with a damp cloth.
Questions &
Q What’s wrong when the oven light will not glow?
A There may be several reasons why the oven light will not glow.
Light bulb has blown
Door is not closed
Q Does microwave energy pass through the viewing screen in the door?
A No. The holes, or ports, are made to allow light to pass; they do not let
microwave energy through.
Q Why does the beep tone sound when a pad on the Control Panel is
A The beep tone sounds to assure that the setting is being properly entered.
Q Will the microwave oven be damaged if it operates empty?
A Yes Never run it empty or without the glass tray.
Q Why do eggs sometimes pop?
A When baking, frying, or poaching eggs, the yolk may pop due to steam
build up inside the yolk membrane. To prevent this, simply pierce the yolk
before cooking. Never microwave eggs in the shell.
Q Why is standing time recommended after microwave cooking is over?
A After microwave cooking is finished, food keeps on cooking during
standing time. This standing time finishes cooking evenly throughout the
food. The amount of standing time depends on the density of the food.
Q Is it possible to pop corn in a microwave oven?
A Yes, if using one of the two methods described
1 Popcorn-popping utensils designed specifically for microwave cooking.
2 Prepackaged commercial microwave popcorn that contains specific
times and power outputs needed for an acceptable final product.
Q Why doesn’t my oven always cook as fast as the cooking guide says?
A Check your cooking guide again to make sure you’ve followed directions
correctly, and to see what might cause variations in cooking time.
Cooking guide times and heat settings are suggestions, chosen to help
prevent overcooking, the most common problem in getting used to a
microwave oven. Variations in the size, shape, weight and dimensions of
the food require longer cooking time. Use your own judgement along
with the cooking guide suggestions to test food condition, lust as you
would do with a conventional cooker.
