Oven Vents
The oven vents are located around the sides of the oven cavity. Warm air may be released from the top and bottom vents before, during and after cooking. It is normal to see steam escaping from these vents, and condensation may collect in this area. This area may be warm when the oven is in use. Do not block any vents, since they are important for air circulation.
Cooling Fan
The cooling fan runs during all cooking modes. The fan can be heard when it is running, and warm air may be felt as it is released from the oven vents. The fan may also run after the oven is off.
Convection Fan
The convection fan operates during all convection modes. When the oven is operating in a convection mode, the fan turns off automatically when the door is opened.
Oven light
The oven light turns off to save energy after one minute with the door open. To turn the light back on, close the door and open it again.

Touch keys
You can activate a function by briefly touching the corresponding touch key. Each time you touch a key a short beep will sound. A long beep will tell you that you have made an invalid input.

Display elements
The display gives you information on the current settings of your appliance. Blinking display elements indicate that an input is required.

How to install the turntable
Place the turntable with the rollers "A" as shown in the picture, on the carrier "B" in the middle of the oven cavity bottom.
The turntable must sit straight on the carrier.

Note: Do not use the appliance if the turntable is not in place. Confirm that all parts are properly seated and that the turntable rotates freely when the microwave is operated.
Inserting the wire rack
1. Place rack securely in the four plastic supports.

Note: Rack must not touch metal walls or back of microwave.
2. Place food on the rack.
CAUTION
Execute the following sections prior to operating:
Once the appliance has been properly connected, 12:00 will be displayed as the time of day. To set the correct time, proceed as follows:
The clock will also be displayed when your appliance is turned off. Please refer to the chapter “Basic Settings” on how to hide the clock.
To remove the new oven smell, heat up the appliance when it is empty and closed. One hour with Convection at 350° F (180 °C) is ideal. Ensure that no packaging remnants have been left in the oven cavity.
The oven light turns on and the appliance starts heating.
Before using accessories for the first time, thoroughly clean them with hot soapy water and a soft dish cloth.
Apply the included program label in the desired language to the side of the oven cavity, as indicated on the leaflet that carries the program label.
Suitable ovenware
Utility dishes, loaf dishes, pie plates, cake plates, liquid measuring cups, casseroles and bowls without metallic trim (e.g. Pyrex®, Anchor Hocking™, Corning Ware®, Emile Henry, etc.).
Bowls, cups, serving plates and platters without metallic trim.
Plastic wrap (as a cover) - lay the plastic wrap loosely over the dish and press it to the sides. Vent plastic wrap by turning back one edge slightly to allow excess steam to escape. The dish should be deep enough so that the plastic wrap will not touch the food.
Microwave-safe plastic dishes, cups, semi-rigid freezer containers and plastic bags for short cooking times. Use these with care because the plastic may soften from the heat of the food.
Paper towels, wax paper, parchment paper, paper napkins and paper plates with no metallic trim or design. Look for the manufacturers label for any special instructions for use in the microwave oven.
Unsuitable ovenware
Metal shields the food from microwave energy and produces uneven cooking. Also, avoid metal skewers, thermometers or foil trays. Metal utensils can cause arcing, which can damage your microwave oven.
Bowls, cups, serving plates and platters with metallic trim.
Avoid large sheets of aluminum foil because they hinder cooking and may cause harmful arcing. Use small pieces of foil to shield poultry legs and wings. Keep ALL aluminum foil at least 1 inch (25 mm) from the side walls of the oven cavity and door of the microwave.
Wooden bowls and boards will dry out and may split or crack when you use them in the microwave oven. Baskets made of wood will react in the same way.
Be sure to leave openings for steam to escape from covered cookware. Pierce plastic pouches of vegetables or other food items before cooking. Tightly closed pouches may explode.
Avoid using brown paper bags. They absorb heat and can burn.
Any utensil that is cracked, flawed or chipped may break in the oven.
Remove metal twist ties from plastic or paper bags. They become hot and could cause a fire.
Ovenware test
Do not turn on the microwave unless there is food inside. The following ovenware test is the only exception to this rule. Perform the following test if you are unsure whether your ovenware is suitable for use in the microwave:
1. Heat the empty ovenware at maximum power for ½ to 1 minute.
2. Check the temperature occasionally during that time. The ovenware should still be cold or warm to the touch. The ovenware is unsuitable if it becomes hot or if sparks are generated.
You can select from 10 different microwave power levels. If you do not set a power level, the microwave will automatically operate at the highest power level 10. The table below provides suggested power levels for various types of food that can be prepared in the microwave.


The appliance must be turned off.

To help you achieve the best possible results from your microwave oven, read the following suggestions below:
Foods taken from the freezer or refrigerator take longer to cook.
Small pieces of food cook faster than large ones. Pieces similar in size and shape will cook more evenly when cooked together. For more even results, reduce the power levels when cooking large pieces of food.
Very moist foods cook more evenly because microwave energy heats water molecules very efficiently.
Stir foods such as casseroles and vegetables from the outside to the center to distribute the heat more evenly. This will allow the food to cook faster. (Constant stirring is not necessary.)
Turn over foods such as pork chops, roasts or whole cauliflower halfway through the cook time. This will help to expose all sides equally to microwave energy.
Place delicate areas of food items, such as asparagus tips, toward the center of the turntable tray.
Arrange unevenly shaped foods, such as chicken pieces or salmon, with the thicker or meatier parts toward the outside of the turntable tray.
After removing the food from the microwave, cover the food with foil or a casserole lid and let it stand to finish cooking. This will help the food finish cooking in the center and avoids overcooking the outer edges. The length of stand time depends on the density and surface area of the food items.
Sandwiches and many other food types containing pre-baked bread should be wrapped in paper towels or wax paper prior to placing in the microwave to help prevent the food items from drying out while heating.
Convection cooking circulates hot air through the oven cavity with a fan. The constantly moving air surrounds the food to heat the outer portion quickly, creating even browning and sealed-in flavor by the constant motion of hot air over the food surfaces. You can set a temperature range from 200 to 450° F (100 to 230°C).
Notes
CAUTION
The oven door and exterior and the wire rack will become hot during Convection. Always use oven mits.
Cookware tips for Convection
Recommended for all types of baked products, especially where browning is important. Dark or dull finish metal pans are best for breads and pies because they absorb heat and produce crisper crust. Shiny aluminum pans are better for cakes, cookies or muffins because they reflect heat and help produce a light tender crust.
Best suited for egg and cheese recipes due to the cleanability of glass.
