RSFEG031EMNMicrowave Cooking Appliance

NOTE This device complies with part 18 of the FCC Rules. 1, Before commissioning this oven please read this instruction manual and keep it carefully. 2, There must be more than 30cm high space necessary above the top surface of oven. 3, Do not repair the oven yourself, please consult an authorized expert. 4, The contents of feeding bottles and bay food jars are to be stirred or shaken and the temperature is to be checked before consumption, in order to avoid burns. 5, Check the oven and the cable regularly for damage. If there is any kind of damage, the oven should not be used. „ Do not attempt to operate this oven with the door open since open- door operation can result in harmfulexposure to microwave energy. It is important not to defeat or tamper with the safety interlocks. „ Carefully clean door seala and sealing surfaces. „ Do not operate the oven if it is damaged. It is particularly important that the oven door close properly and that there is no damage to the : (1) door(bent). (2) hinges and latches( broken or loosened). (3) door seals and sealing surfaces. „ Utensils sould be checked to ensure that they are suitable for use in microwave ovens. „ When heating food in plastic or paper containers, check the oven frequently due to the possibility of ignition. „ Microwave heating of beverages can result in delayed eruptive boiling, therefore care has to be taken when handling the container. „ If smoke is observed, switch off or unplug the appliance and keep the door closed in order to stifle any flames. „ Egg in their shell and whole hard- bolled eggs shall not be heated in microwave ovens since they may explode. „ If the door or door seals are damaged. The oven must not be operated until it has been repaired by a trained person. „ Liquids or other foods must not be heated in sealed containers since they are liable to explode. Warning: 1, It is hazardous for anyone other than a trained person to carry out any service or repair operation, which involves the removal of any cover which gives protection against exposure to microwave energy. 2, Only allow children to use the oven without supervision when adequate instructions have been given so that the children is able to use the oven in a safe way and understands the hazards of improper use. 3, If the supply cord is damaged, it must be replaced by the manufacture of its service agent or a similarly qualified person in order to avoid a hazard. 4, This product will make disturbance in AV product, if any disturbance is occurred, use different electrical source jack to supply electricity or use low power or away from them. Note: THE MANUFACTURER IS NOT RESPONSIBLE FOR ANY RADIO OR TV INTERFERENCE CAUSED BY UNAUTHORIZATED MODIFICATIONS TO THIS EQUIPMENT .SUCH MODIFICATIONS COULD VOID THE USER’S AUTHORITY TO OPERATE THE EQUIPMENT.

When the microwave oven is plug into a wall outlet, the oven display “0:00”, Press “clock”, the LCD display 00:00, you can set the clock (You can press stop if you don’t want to set the clock). Then you can select cooking mode. There are several cooking modes, you can select power, auto cook, and auto defrosts, and so on. There is program in the Microcontroller of the control board, the cooking time and power level are pre-set in the program. Here we can choose the power level to cook food, so we can see how the microwave oven work. Put the food in the cavity glass tray, then press “power”, we can select one of ten power level (P100 to P10). We can select the difference power level by increasing the impulse ratio. The control of the power elements uses the keyboard commands. Then press “1-9”, we can set cooking time. As a final step, press “start”. (If you want to stop cooking, press “stop” or “pause”). Then magnetron power supply system will work, and High Voltage transformer, High Voltage diode, High Voltage capacitor will supply power to magnetron, and about 3 second the magnetron will work. The magnetron is a radio transmitter. . If it was on a radio mast it would be able to send radio signals a long way. But it is inside a metal box which keeps the signal in. The frequency of the transmitter is 2450MHz (megahertz), which is a wavelength of 12cm, rather than short waves, medium waves or long waves. In microwave cooking, the radio waves penetrate the food and excite water and fat molecules pretty much evenly throughout the food. Anything with water in it has all these molecules being moved this way and that by the electrical field, and heated up. Microwaves in this frequency range have another interesting property: they are not absorbed by most plastics, glass or ceramics. The dishes, walls of the oven , etc, don't pick up radio, so don't get heated up. The cooling system will start working, the lamp will be lighted, and the turntable will rotate, at the same time when the power supply system work. After we press “start”, the fan will running, it can get rid of its excess heat, and cooling the magnetron and High voltage transformer. You mustn't block the vents or the oven will overheat. At the same time, the turntable motor will turn. The turning system including the turntable motor, shaft, roller, and glass tray will start working.It is used for better cooking. An AC motor rotates the plate with constant speed about 5 rpm. When the start button is pushed the motor starts. A light that lights when the door is opened and when the oven is working. So we can see the food in cavity clearly! A ring alarm that makes a sound when cooking is done.
