User Instructions
COVERING
Covers hold in moisture, allow for more even heating and 
reduce cooking time. 
Venting plastic wrap or covering with wax paper allows 
excess steam to escape.
STANDING TIME
When you cook with regular ovens, foods such  
as roasts or cakes are allowed to stand to finish cooking or 
to set. 
Standing time is especially important in microwave 
cooking. Note that a microwaved cake is not placed on a 
cooling rack.
VENTING
After covering a dish with plastic wrap, you vent the plastic 
wrap by turning back one corner so excess steam can 
escape.
SHIELDING
In a regular oven, you shield chicken breasts or baked 
foods to prevent over-browning. When microwaving, you 
use small strips of foil to shield thin parts, such as the tips 
of wings and legs on poultry, which would cook before 
larger parts.
ARCING
Arcing is the microwave term for sparks in the oven. Arcing is caused by:
■   Metal or foil touching the side of the oven.
■   Foil that is not molded to food (upturned edges act like 
antennas).
■   Metal such as twist-ties, poultry pins, gold-rimmed 
dishes.
■   Recycled paper towels containing small metal pieces.
■   Plates or dishes with a metallic trim or glaze with a 
metallic sheen.
