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:
    1. Do not overheat the liquid.
    2. Stir the liquid both before and halfway through heating it.
    3. Do not use straight-sided containers with narrow necks.
    4. After heating, allow the container to stand in the microwave oven for a short time before removing the container.
    5. 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.

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 is 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 manufacturers 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: Does 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 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.

Cooking Utensils

MICROWAVE-SAFE

• 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 your 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.

NOT MICROWAVE-SAFE

• 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 metallic 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.
• 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.

Use Your Microwave Oven Safely

DO NOT

• 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.

DO

• 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 or 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

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 II. 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.

This diagram explains how microwaves cook food. It shows electricity being converted into microwave energy by the MAGNETRON. This energy travels through a WAVEGUIDE to the OVEN CAVITY. Inside the cavity, microwaves are reflected off the metal walls and door screen. They then penetrate the food and are absorbed by water molecules. This absorption causes the water molecules to vibrate, generating friction and thus HEAT, which cooks the food. The diagram also indicates that microwaves penetrate food to a depth of 1.5-2 inches, with heat spreading inwards by conduction.
