[. . . ] The marked rating of the extension cord should be equal to or greater than the electrical rating of the appliance. INSTALLATION 1. Steady, flat location This oven should be set on a steady, flat surface. If all vents are covered during operation, the oven may overheat and, eventually, oven failure. 3. Away from radio and TV sets Poor television reception and radio interference may result if the oven is located close to a TV, Radio antenna, feeder and so on. [. . . ] · Do not let the timer continue to operate after removing or when there is no food. COOKING GUIDE COOKING UTENSILS Recommended Use Glass and glass-ceramic bowls and dishes - Use for heating or cooking. Microwave browning dish - Use to brown the exterior of small items such as steaks, chops, or pancakes. Leave a small opening for some steam to escape and avoid placing it directly on the food. Paper towels and napkins - Use for short term heating and covering; they absorb excess moisture and prevent spattering. Do not use recycled paper towels, which may contain metal and can catch fire. Paper plates and cups - Use for short-term heating at low temperatures. Do not use recycled paper, which may contain metal and can catch fire. Thermometers - Use only those labeled "Microwave Safe" and follow all directions. Conventional thermometers may be used once the food has been removed from the oven. COOKING TECHNIQUES Stirring Stir foods such as casseroles and vegetables while cooking to distribute heat evenly. Food at the outside of the dish absorbs more energy and heats more quickly, so stir from the outside to the center. The oven will turn off when you open the door to stir your food. Arrangement Arrange unevenly shaped foods, such as chicken pieces or chops, with the thicker, meatier parts toward the outside of the turntable where they receive more microwave energy. To prevent overcooking, place thin or delicate parts toward the center of the turntable. Shielding Shield food with narrow strips of aluminum foil to prevent overcooking. Areas that need shielding include poultry wing-tips, the ends of poultry legs, and corners of square baking sdishes. Larger amounts can damage your oven. Limited Use Aluminum foil - Use narrow strips of foil to prevent overcooking of exposed areas. Ceramic, porcelain, and stoneware - Use these if they are labeled "Microwave Safe". If they are not labeled, test them to make sure they can be used safely. Straw, wicker, and wood - Use only for short-term heating, as they can be flammable. Turning Turn foods over midway through cooking to expose all parts to microwave energy. This is especially important with large items such as roatsts. Standing Foods cooked in the microwave build up internal heat and continue to cook for a few minutes after the oven stops. Let foods stand to complete cooking, especially foods such as roasts and whole vegetables. Roasts need this time to complete cooking in the center without overcooking the outer areas. All liquids, such as soup or hot chocolate, should be shaken or stirred when cooking is complete. When heating baby food, stir well and test the temperature before serving. [. . . ] Both the glass tray and roller guide must always be used in the oven before cooking. Then microwave energy will be instantly switched off and the time setting will maintain until the door is closed. It is caused by steam from cooking food hitting the cool oven surface. * Q : Does microwave energy pass through the viewing screen in the door? [. . . ]
