IMPORTANT SAFETY INSTRUCTIONS

READ CAREFULLY AND KEEP FOR FUTURE REFERENCE

WARNING : To prevent fire, burns, electric shock and other warnings:

Listed below are, as with all appliances, certain rules to follow and safeguards to assure high

performance from this oven:

1. Do not use the oven for any reason other than food

preparation, such as for drying clothes, paper, or any

other nonfood items or for sterilizing purposes.

2. Do not use the oven when empty, this could damage the

oven.

3. Do not use the oven cavity for any type of storage, such

as papers, cookbook, cookware, etc.

4. Do not operate the oven without the glass tray in place. Be

sure it is properly sitting on the rotating base.

5. Make sure you remove caps or lids prior to cooking when

you cook food sealed in bottles.

6. Do not put foreign material between the oven surface and

door. It could result in excessive leakage of microwave

energy.

7. Do not use recycled paper products for cooking. They may

contain impurities which could cause sparks and/or fires

when used during cooking.

8. Do not pop popcorn unless popped in a microwave

approved popcorn popper or unless it's commercially

packaged and recommended especially for microwave

ovens. Microwave popped corn produces a lower yield

than conventional popping; there will be a number of

unpopped kernels. Do not use oil unless specified by the

manufacturer.

9. Do not cook any food surrounded by a membrane, such

as egg yolks, potatoes, chicken livers, etc., without first

piercing them several times with a fork.

10. Do not pop popcorn longer than the manufacturer's

directions. (popping time is generally below 3 minutes).

Longer cooking does not yield more popped corn, it can

cause scorchings and fire. Also, the cooking tray can

become too hot to handle or may break.

11. If smoke is observed, switch off or unplug the appliance

and keep the door closed in order to stifle any flames.

12. When heating food in plastic or paper containers, keep an

eye on the oven due to the possibility of ignition.

13. The contents of feeding bottles and baby food jars shall be

stirred or shaken and the temperature checked before

consumption, in order to avoid burns.

14. Always test the temperature of food or drink which has

been heated in a microwave oven before you give it to

somebody, especially to children or elderly people. This is

important because things which have been heated in a

microwave oven carry on getting hotter even though the

microwave oven cooking has stopped.

15. Eggs in their shell and whole hard-boiled eggs should not

be heated in microwave ovens since they may explode,

even after microwave heating has ended;

16. Keep the waveguide cover clean at all times. Wipe the

oven interior with a soft damp cloth after each use. If you

leave grease or fat anywhere in the cavity it may

overheat, smoke or even catch fire when next using the

oven.

17. Never heat oil or fat for deep frying as you cannot control

the temperature and doing so may lead to overheating

and fire.

18. Liquids, such as water, coffee, or tea are able to be

overheated beyond the boiling point without appearing to

be boiling due to surface tension of the liquid. Visible

bubbling or boiling when the container is removed from

the microwave oven is not always present. THIS COULD

RESULT IN VERY HOT LIQUIDS SUDDENLY BOILING

OVER WHEN A SPOON OR OTHER UTENSIL IS

INSERTED INTO THE LIQUID.

To reduce the risk of injury to persons:

a) Do not overheat the liquid.

b) Stir the liquid both before and halfway through heating

c) Do not use straight-sided containers with narrow necks.

d) After heating, allow the container to stand in the

microwave oven for a short time before removing the

container.

e) Use extreme care when inserting a spoon or other

utensil into the container.

19. Oven should be cleaned regularly and any food deposits

removed.

20. Failure to maintain the oven in a clean condition could

lead to deterioration of the surface that could adversely

affect the life of the appliance and possibly result in a

hazardous situation.

21. This appliance is not intended for use by

persons(including children) with reduced physical,

sensory or mental capabilities, or lack of experience and

knowledge, unless they have been given supervision or

instruction concerning use of the appliance by a person

responsible for their safety.

22. Children should be supervised to ensure that they do not

play with the appliance.

SAVE THESE INSTRUCTIONS

QUESTIONS AND ANSWERS

*Q : Why do eggs sometimes pop?

*A : When baking or poaching eggs, the yolk may pop due to steam build-up inside the yolk membrane. To

prevent this, simply pierce the yolk with a toothpick before cooking. Never cook eggs without piercing their

shells.

*Q : Why this standing time recommended after the cooking operation has been completed?

*A : Standing time is very important.

With microwave cooking, the heat is in the food, not in the oven. Many foods build up enough internal heat

to allow the cooking process to continue, even after the food is removed from the oven. Standing time for

joints of meat, large vegetables and cakes is to allow the inside to cook completely, without overcooking

the outside.

*Q : Will the microwave oven be damaged if it operates while empty?

*A : Yes. Never run it empty.

*Q : Why does my oven not always cook as fast as the microwave cooking guide says?

*A : Check your cooking guide again, to make sure youve followed directions exactly ; and to see what might

cause variations in cooking time. Cooking guide times and heat settings are suggestions, to help prevent

over-cooking... the most common problem in getting used to a microwave oven.

Variations in the size, shape and weights and dimensions could require longer cooking time. Use your

own judgement along with the cooking guide suggestions to check whether the food has been properly

cooked just as you would do with a conventional cooker.

*Q : Can I operate my microwave oven without the turntable or turn the turntable over to hold a large dish?

*A : No. If you remove or turn over the turntable, you will get poor cooking results. Dishes used in your oven

must fit on the turntable.

*Q : Is it normal for the turntable to turn in either direction?

*A : Yes. The turntable rotates clockwise or counterclockwise, depending on the rotation of the motor when the

cooking cycle begins.

*Q : Can I pop popcorn in my microwave oven? How do I get the best results?

*A : Yes. Pop packaged microwave popcorn following manufactures guidelines or use the preset POPCORN

pad. Do not use regular paper bags. Use the listening test by stopping the oven as soon as the popping

slows to a pop every 1 or 2 seconds. Do not repop unpopped kernels. Do not pop popcorn in glass

cookware.

*Q : Can the oven be used with the glass tray or roller guide removed?

*A : No. Both the glass tray and roller guide must always be used in the oven before cooking.

*Q : Can I open the door when the oven is operating?

*A : The door can be opened anytime during the cooking operation. Then microwave energy

will be instantly switched off and the time setting will maintain until the door is closed and START is

touched.

*Q : Why do I have moisture in my microwave oven after cooking?

*A : The moisture on the side of your microwave oven is normal. It is caused by steam from cooking food

heating the cool oven surface.

*Q : Dose microwave energy pass through the viewing screen in the door?

*A : No. The metal screen bounces back the energy to the oven cavity. The holes are made to allow light to

pass through. They do not let microwave energy pass through.

COOKING UTENSILS

Î»½±³³»²¼»¼ Ë-»

Glass and glass-ceramic bowls and Dishes - Use for heating or cooking.

 Microwave browning dish - Use to brown the exterior of small items such as steaks, chops, or pancakes.

Follow the directions provided with you browning dish.

 Microwaveable plastic wrap - Use to retain steam. Leave a small opening for some steam to escape and

avoid placing it directly on the food.

 Wax paper - Use as a cover to prevent spattering.



Paper towels, paper plates, napkins and cups - Use for short term heating and covering; they absorb excess

moisture and prevent spattering. Always attend the oven closely. Only use to absorb fat and moisture when

warming food. Pay special attention as over-heating may cause a fire in your oven. Do not use re-cycled paper

products, e.g. kitchen roll unless they say they are specifically designed for use in a microwave oven. These

products contain impurities which may cause sparks and/or fires when used.



Thermometers - Use only those labeled Microwave Safe and follow all directions. Check the food in several

places. Conventional thermometers may be used once the food has been removed from the oven.

 Microwave cling film, microwave roasting bags - Microwave cling film and bags must be vented for steam

to escape, pierce in 4~5 places. Do not use plastic or metal ties as they may melt or catch fire due to electrical

arcing.

Ô·³·¬»¼ Ë-»

Aluminum foil - Use narrow strips of foil to prevent overcooking of exposed areas. Using too much foil can

damage your oven, so be careful.

 Ceramic, porcelain, and stoneware - Use these if they are labeled Microwave Safe. If they are not

labeled, test them to make sure they can be used safely. Never use dishes with metalic trim.

 Plastic - Use only if labeled Microwave Safe. Other plastics can melt.



Thin plastic, paper, straw and wooden containers - Always attend the oven closely. Look at the oven from time to

time when cooking or reheating food in disposable containers of plastic, paper or other combustible material. Only use

for warming food. Pay special attention as over-heating may cause a fire in your oven.

Ò±¬ Î»½±³³»²¼»¼

 Glass jars and bottles - Regular glass is too thin to be used in a microwave, and can shatter.

 Paper bags - These are a fire hazard, except for popcorn bags that are designed for microwave use.

 Styrofoam plates and cups - These can melt and leave an unhealthy residue on food.



Plastic storage and food containers - Containers such as margarine tubs can melt in the microwave.

 Metal utensils - These can damage your oven. Remove all metal before cooking.

COOKING INSTRUCTIONS

Only use utensils that are suitable for use in microwave ovens.

UTENSILS TEST

Place the utensil in question next to a glass measure filled with water, in the microwave oven. Microwave at

high power for 1-2 minutes. If the water heats up, but the utensil remains cool, the utensil is microwave-safe.

However if the utensil becomes warm, microwaves are being absorbed by the utensil and it should not be in the

microwave oven. You probably have many items on hand in your kitchen right now that can be used as cooking

equipment in your microwave oven. Read through the following checklist.

USE YOUR MICROWAVE OVEN SAFELY

Ù»²»®¿´ Ë-»

Do not attempt to defeat or tamper with safety interlocks.

Do not place any object between the oven front frame and the door or allow residue to build up on sealing

surfaces. Wipe with a mild detergent, rinse and dry. Never use abrasive powders or pads.

Do not subject the oven door to strain or weight such as a child hanging on an open door.

This could cause the oven to fall forward resulting in injury to you and damage to the oven.

Do not operate the oven if door seals or sealing surfaces are damaged; or if door is bent; or if hinges are loose

or broken.

Do not operate the oven empty. This will damage the oven.

Do not attempt to dry clothes, newspapers or other materials in the oven. They may catch on fire.

Do not use recycled paper products as they may contain impurities which may cause sparks or fires.

Do not hit or strike the control panel with hard objects. This can damage the oven.

Ú±±¼

Always use the minimum recipe cooking time. It is better to undercook rather than overcook foods.

Undercooked foods can be returned to the oven for more cooking. If food is overcooked, nothing can be done.

Heat small quantities of food or foods with low moisture carefully. These can quickly dry out, burn or catch on

fire.

Do not heat eggs in the shell. Pressure may build up and eggs can explode.

Potatoes, apples, egg yolks and sausages are examples of food with non-porous skins.

These must be pierced before cooking to prevent bursting.

Do not attempt to deep fat fry in your microwave oven.

Always stir liquids before heating. Heated liquids can erupt, if not mixed with air.

Do not leave the oven unattended while popping corn.

Do not pop corn in a paper bag unless it is the commercially prepared Microwave Popcorn product. The kernels

can overheat and ignite a brown paper bag.

Do not put packaged Microwave Popcorn bags directly on the oven tray. Place the package on a microwave

safe glass or ceramic plate to avoid overheating and cracking the oven tray.

Do not exceed the Microwave Popcorn manufacturers' suggested popping time. Longer popping does not yield

more popcorn but it can result in scorch, burn of fire. Remember, the Popcorn bag and tray can be too hot to

handle. Remove with caution and use pot holders.

Ensure all food deposits are cleaned off, as they can carbonize if left.

Arcing is the microwave term for sparks in the oven.

Arcing is caused by:

 Metal or foil touching the side of the oven.

 Foil not molded to food (upturned edges act like antennas).

 Metal, such as twist-ties, poultry pins, or gold rimmed dishes, in the microwave.

 Recycled paper towels containing small metal pieces being used in the microwave.

MICROWAVING PRINCIPLES

Microwave energy has been used in this country to cook and reheat food since early experiments with RADAR in

World War ll. Microwaves are present in the atmosphere all the time, both naturally and manmade sources.

Manmade sources include radar, radio, television, telecommunication links and car phones.

HOW MICROWAVES COOK FOOD

Microwave oven is a Group 2 ISM equipment in which radiofrequency energy is intentionally generated

and used in the form of electromagnetic radiation for the treatment of material. This oven is a Class B

equipment suitable for use in domestic establishments and in establishments directly connected to a low

voltage power supply network which supplies buildings used for domestic purposes.

1 Gallon = 128 fl.oz. (UK 160 fl.oz.) = 3840 ml (UK 4500 ml)

Then they pass through

the cooking containers to

be absorbed by the water

molecules in the food, all

foods contain water to a

more or lesser extent.

The microwaves cause the water molecules to

vibrate which causes FRICTION, i.e. HEAT. This

heat then cooks the food. Microwaves are also

attracted to fat and sugar particles, and foods high

in these will cook more quickly. Microwaves can

only penetrate to a depth of 1

- 2 inches(4-5cm)

and as heat spreads through the food by

conduction, just as in a traditional oven, the food

cooks from the outside inwards.

In a microwave oven,

electricity is converted

into microwave by the

MAGNETRON.
