Precautions:
1, the location of the microwave oven is very important. 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. Keep a certain distance from TV and radio, otherwise it will affect the visual and auditory effects.
Don't turn on the switch when not in use. When cooking food, don't put it in the oven. Don't let the microwave oven run with no load, or it will damage the magnetron. In order to prevent careless no-load operation, a glass filled with water can be built in the furnace cavity.
