Introduction The new Advantium oven uses breakthrough Speedcook technology to harness the power of light. The Advantium oven cooks the outside of foods much like conventional radiant heat, while also penetrating the surface so the inside cooks simultaneously. While halogen light is the primary source of power, a "microwave boost” is added with certain foods. Foods cook evenly and fast, retaining their natural moisture.

Cooking Times ■ When speedcooking preprogrammed foods, you may see OPTIMIZING COOK TIME in the display several seconds after you press START/PAUSE. The oven automatically senses the electrical voltage level in your home and adjusts the cooking time up or down for proper cooking. Fan/Vent To remind you that you have food in the oven, the oven will display COOK TIME COMPLETED and beep once a minute until you either open the oven door or press the CLEAR/OFF pad.
Speed Cook System Halogen Lamp and Ceramic Heaters • One 500 watt halogen bulb and one 700 watt ceramic heater cook food from above. • One 375 watt ceramic heater cooks food from below. Rear Convection Heat Element • Operates when using bake. Microwave • A microwave “boost” is automatically added with certain foods.
Speedcook Power Levels Lower Heater Advantium uses power from a high-intensity halogen light, ceramic heaters, and microwaves to cook food from the top, bottom, and interior simultaneously, sealing in moisture and flavor. The lower heater is a 375 watt ceramic heater. It operates in speedcook, oven/bake, and warm modes. The lower heater assists in browning foods on the bottom. When using preset Speedcook recipes on the food menu, power levels are preselected.
The following chart shows the predicted compensation times based on a 12-minute speedcook selection (such as Biscuits, Refr; Large). Thermal Compensation Note: Thermal compensation only occurs when using a preselect menu item in Speedcook. These items require compensation for accurate and consistent cooking results.
