1 Before using the microwave oven, carefully read the instruction manual provided by the manufacturer, know your microwave oven and accept the instructions. If the power supply is insufficient, the light in the furnace will appear dim. At this time, if it continues to be used, it will damage the safety equipment and should be stopped immediately.

2. The microwave oven should be placed in a ventilated place, and there should be no magnetic substances nearby, so as not to interfere with the uniform state of the magnetic field in the furnace cavity and reduce the working efficiency. The microwave oven should be flat, away from the fire and faucet. Do not cover the ventilation behind the furnace or on both sides. It is best to have a distance of at least 5 cm (2 inches) from the wall to make the hot air easy to dissipate.

3. When using a rotary microwave oven, the container containing food must be placed in a special plate for the microwave oven, not directly in the oven cavity. If the whole bag of food is attached with a metal clip, it should be removed first, and the metal strip of the plastic cooking bag should be tied tightly, so it should not be used. If a spark occurs in the furnace, stop the furnace immediately.

4. After the food is put in, close the oven door to ensure that the interlock switch and safety switch are closed. During heating, people should stay away from the microwave oven or be at least 1 m away from the microwave oven to reduce radiation.
