Turning on a Dual Element OFF position Single element Dual element HI position HI position 1. Select a dual element, and find its control knob. 2. Push the control knob in and turn it in either direction to use it as a single element or a dual element.
USING THE PROPER COOKWARE The size and type of cookware will influence the settings needed for the best cooking results. Cookware should have flat bottoms that make good contact with the entire surface heating element. Using the correct cookware can prevent many problems, such as uneven cooking or extended cooking times.
Page 29
Choosing Cookware The cookware material determines how evenly and quickly heat is transferred from the surface element to the pan bottom. Recommended • Aluminum - Excellent heat conductor. Some types of food will cause it to darken (anodized aluminum cookware resists staining and pitting).
OVEN BEFORE USING THE OVEN Read the instructions for each feature and cooking mode in this manual carefully before using the oven. CAUTION • Do not use any type of foil or oven liner to cover the oven bottom. These items can trap heat or melt, resulting in damage to the product and risk of shock, smoke or fire.
WARNING FOOD POISONING HAZARD • Do not let food sit in oven more than one hour before or after cooking. Doing so can result in food poisoning or sickness. • Foods that can easily spoil such as milk, eggs, fish, meat or poultry, should be chilled in the refrigerator first.
OVEN DOOR Oven heating elements and, if in operation, convection fan will temporarily shut off any time door is opened, and will resume when door is closed within 3 minutes. NOTE: • Do not leave the door open any longer than necessary. If the door is left open too long for over 3 minutes, the cooking mode will be automatically cancelled.

PREHEATING Preheating is generally desirable, although not absolutely necessary in all circumstances. • For oven modes that utilizes preheat, the control will automatically enter preheat mode and show "100°F" after START/OK is pressed to turn on the oven. When the oven temperature reaches 100°F, the display will show the current oven temperature, and will continue to show the oven temperature increasing until the set temperature is reached.
COOKING MODES The various baking modes (Bake, Conv Bake, Conv Roast, and Pizza) have a 10-hour time limit, after which the control will automatically end the baking mode. Broil and Warm modes have a 3-hour time limit. If desired, these modes can be restarted after the time limit expires.
BAKE The Bake mode uses heat from the lower heating element to cook food. This mode works best with food placed on a single rack. Always preheat the oven first and place food centrally near the middle racks. Setting the Bake Mode 1.
8. Press CANCEL/OFF when cooking is finished, and remove the food from the oven. If a Cook Time is set and the countdown reaches 00:00, the oven turns o ff automatically. The display shows "End" and a cook end tone sounds for 1 minute or stops when the oven door is opened.

The oven turns on and starts preheating. As the oven preheats and reaches 100°F, the display will show the current oven temperature, and will continue to show the oven temperature increasing until the set temperature is reached.
CONV ROAST The Convection Roast mode uses heat from both upper and lower elements and air movement from the convection fan to enhance cooking efficiency and evenness across multiple racks. Ideal for roasting meats and poultry. Heated air circulates around the food from all sides, sealing in juices and flavors.
NOTE: • Do not leave the door open any longer than necessary when placing food. If the door is left open too long for over 3 minutes, the cooking mode will be automatically cancelled. 8. Press CANCEL/OFF when cooking is finished, and remove the food from the oven.

As the oven preheats and reaches 100°F, the display will show the current oven temperature, and will continue to show the oven temperature increasing until the set temperature is reached.
WARM The Warm mode uses heat from the lower heating element to maintain oven temperature at around 175°F (79°C). It will keep cooked food warm for serving up to 3 hours after cooking has finished. Cover foods that need to remain moist and do not cover foods that should be crisp.
BROIL The Broil mode uses intense heat from the upper heating element to sear foods. This mode works best for tender cuts of meat, fish, and thinly cut vegetables, and is ideal for toasting, melting cheese, browning and searing surface. Food should be placed near the upper racks, and should not be cooked for too long on each side of the food.
TIPS AND TECHNIQUES BAKE Baking is cooking with heated air. The lower element in the oven is used to heat the air but no fan is used to circulate the heat. Follow the recipe or convenience food directions for baking temperature, time and rack position.
Page 46
CONVECTION BAKE Convection Bake uses heat from the lower heating element and air movement from the convection fan to enhance cooking efficiency and evenness across multiple racks. Reduce recipe baking temperatures by 25°F (15°C). • For best results, foods should be cooked uncovered, in low-sided pans t o take advantage of the forced air circulation.
Page 47
Foods recommended for convection bake mode: Appetizers, Biscuits, Cakes, Casseroles, Coffee Beans, Cookies (2 to 4 racks), Cream Puffs, Popovers, Yeast Breads, One-Dish Entrées, Oven Meals (rack positions 3 and 4), and Air Leavened Foods (Soufflés, Meringue, Meringue- Topped Desserts, Angel Food Cakes, Chiffon Cakes). Convection Bake Chart Reduce standard recipe temperature by 25 ºF (15 °C) for Convection Bake.
