If you follow the instructions, your oven will provide you with many years of good service. MODEL:EM920AFW-P 1 SPECIFICATIONS PRECAUTIONS TO AVOID POSSIBLE EXPOSURE TO EXCESSIVE MICROWAVE ENERGY (a) Do not attempt to operate this oven with the door open since this can result in harmful exposure to microwave energy.It is important not to break or tamper with the safety interlocks. (b) Do not place any object between the oven front face and the door or allow soil or cleaner residue to accumulate on sealing surfaces. (c) Do not operate the oven if it is damaged. It is particularly important that the oven door closes properly and that there is no damage to the: (1) DOOR(dent) (2) HINGES AND LATCHES(broken or loosened) (3) DOOR SEALS AND SEALING SURFACE (d) The oven should not be adjusted or repaired by anyone except properly qualified service personnel.

The oven must be on a leveled surface. 2. The turntable and turntable roller rest must be in the oven during cooking. Place the cookware gently on the turntable and handle it carefully to avoid possible breakage. 3. Incorrect use of browning dish may cause the turntable to break. 4. Use only the specified bag size when using Direct Access Popcorn. 5. The oven has several built-in safety switches to ensure that the power remains off when the door is open. Do not tamper with these switches. 6. Do not operate the microwave oven empty. Operating the oven with no food or food that is extremely low in moisture can cause fire, charring or sparking. 7. Do not cook bacon directly on the turntable. Excessive local heating of the turntable may cause the turntable to break. 8. Do not heat baby bottles or baby food in the microwave oven. Uneven heating may occur and could cause physical injury. 9. Do not heat narrow-necked containers, such as syrup bottles. 10. Do not attempt to deep-fry in your microwave oven. 11. Do not attempt home canning in this microwave oven as it is impossible to be sure all contents of the jar have reached boiling temperature. 12. Do not use this microwave oven for commercial purpose. This microwave oven is made for household use only. 13. To prevent delayed eruptive boiling of hot liquids and beverages or scalding yourself, stir liquid before placing the container in the oven and again halfway through cooking time. Let stand in the oven for a short time and stir again before removing the container. 14. Please do notice the food in the microwave oven to avoid burning due to excessive cooking when cooking food in it. 15. When the appliance is operated in the combination mode, children should only use the oven under adult supervision due to the temperatures generated. 16. 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. 1. Read all instructions before using the appliance. 2. Read and follow the specific:" PRECAU- TIONS TO AVOID POSSIBLE EXPOSURE TO EXCESSIVE MICROWAVE ENERGY". 3. As with most cooking appliances,close supervision is necessary to reduce the risk of a fire in the oven cavity. If materials inside the oven ignite: 1.Keep the oven door closed 2.Turn the oven off, and unplug the appliance. 3.Disconnect the power at the fuse or circuit breaker panel. Keep in mind the following rules at all times: 1.Do not overcook food. Carefully attend the appliance when paper,plastic,or other combus- tible materials are placed inside the oven to facilitate cooking. 2.Do not use the oven cavity for storage pur- poses. Do not store combustible items su- ch as bread, cookies, paper products, etc. inside the oven. If lightning strikes the power line, the oven may turn on by itself. 3.Remove wire twist-ties and metal handles from paper or plastic containers/bags before placing them in the oven. 4.This oven must be grounded. Connect only to properly grounded outlet. See"GROUN- DING INSTRUCTIONS". 5. Install or locate this oven only in accordance with the installation instructions provided. 6. Some products such as whole eggs, water with oil or fat, sealed containers and closed glass jars are able to explode and therefore should not be heated in this oven. 7. Use this appliance only for its intended uses as described in the manual. Do not use corrosive chemicals or vapors in this appliance. This oven is specifically designed to heat or cook food. It is not designed for industrial or laboratory use. 8. As with any appliance, close supervision is necessary when used by children. 9. Do not operate this oven if it has a damaged cord or plug, if it is not working properly or if it has been damaged or dropped. 10. This appliance should be serviced only by qualified service technicians. Contact the nearest authorized service facility for examination,repair or adjustment. 11. Do not cover or block any vents on the oven. 12. Do not store or use this appliance outdoors. 13. Do not use this oven near water,for example, near a kitchen sink, in a wet basement, near a swimming pool, or similar locations. 14. Do not immerse cord or plug in water. 15. Keep cord away from heated surfaces. 16. Do not let cord hang over edge of table or counter. 17. When cleaning door and oven surfaces use only mild, nonabrasive soaps or detergents applied with a sponge or soft cloth. Important Safety Instructions SAFETY WARNING— To reduce the risk of the fire, electric shock, injury to persons, or exposure to excessive microwave oven energy when using your appliance, follow basic precautions, including the following: 4 SAVE TH…

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.
