Introduction
You are now the owner of one of the finest and most modern microwave ovens that today’s technology can produce. You are going to make a great team together, but first you
must familiarise yourself with the product. Please take some time and read through this
manual carefully. It will tell you all you need to know about your new microwave oven,
what it will do and how to do it. We wish you many happy years of cooking.
Microwaves and how they work
Microwaves are high-frequency electromagnetic waves closely resembling ordinary daylight or radio waves. But whereas radio waves vary in length from 1 metre to many kilometres, microwaves are only about 12.5 cm long.
A magnetron, converts electrical energy into microwaves. The microwaves are not hot, so
there is no heat in the microwave oven. The microwaves penetrate the food and provide
energy which vibrates the water molecules present in the food. This incredibly rapid vibration produces extreme heat which cooks the food. This explains the mystery of how
hot food can emerge from a cold oven.
Microwaves are not retained in the air or in the food after the door is opened. Microwaves can not penetrate metals, so the oven cavity is lined with metal. The oven door
window is transparent and is lined with a fine metal mesh which prevents the waves from
passing through. The door mechanism is designed in such a manner that the oven will not
operate if the door is open. During manufacture, the microwave ovens are subjected to
stringent processes and testing to ensure that microwave leakage does not occur.
Precautions
1. Do not attempt to operate the oven if the door is bent, the hinges are loose or broken
or if the door no longer closes properly. Report any damage to your dealer or nearest
Defy Service Centre. They will be able to take the necessary corrective action.
2. Do not tamper with or attempt to bypass the door safety interlocks.
3. Do not place or trap any object between the front edge of the oven and the door.
4. Clean up any residue which may accumulate on the door’s inner sealing surface.
5. Liquids or foods should not be heated in sealed containers as they might explode.
6. Do not allow children to use the oven without adult supervision.
7. Any adjustment or repairs should only be undertaken by a qualified service technician.
Electrical installation
Microwave ovens operate off a 15A earthed electrical socket and do not require specialised electrical installation. However improper earthing could result in electrical shocks.
If the supply cord is damaged it must be replaced by a qualified service technician.
The use of an extension cord is not recommended but if one must be used, ensure that the
rating is equal or greater than that of the appliance.

Installation
1. Remove all packaging. Do not remove the clear film on the inside of the door viewing screen.
2. Examine the oven for any damage. ( A misaligned door, a dent in the cabinet)
3. If damaged, do not operate the oven and notify your dealer or the nearest Defy Service Centre immediately.
4. The oven must be placed on a suitable flat, level and stable surface capable of supporting the weight of the product.
5. Install the oven well away from Hi-Fi and TV sets, as broadcast reception could be
negatively affected.
6. Install the oven well away from heaters, or water taps.
7. Allow an air space of at least 30mm around the sides and rear of the oven and
100mm above the oven for ventilation purposes.
8. Do not block any of the air vents on the cabinet.
9. If the oven is not adequately vented , it may overheat and lead to failure.
Safety tips and instructions
1. Do not use the oven for any purpose other than for cooking food.
2. Do not operate the oven when it is empty.
3. Do not use the oven as a storage space.
4. Do not operate the oven without the glass tray and the roller guide in place.
5. Monitor the oven when cooking in plastic or paper containers to avoid accidental
ignition.
6. Avoid using recycled paper products for cooking as these could contain impurities
which could cause sparking.
7. Do not pop popcorn in the oven unless you use microwave popcorn in an approved
bag.
8. Pierce or puncture the skins of non porous foods such as egg yolk, sausages, pumpkins and tomatoes before cooking.
9. Do not place eggs or nuts in their shells in the oven as they might explode.
10. Remove all caps or lids when cooking food in sealed containers.
11. Always test the temperature of food and drinks, especially feeding bottles and baby
food jars, before consumption, to avoid getting burnt.
12. Microwave heating of beverages could result in delayed eruptive boiling, so care
should be taken when handling such containers.
13. Never heat fat or oil in the microwave as the temperature can not be controlled and
combustion could result.
14. Keep the oven and waveguide cover clean at all times. Remove all traces of fat or
grease as these could ignite the next time the oven is used
