In order to keep the food in perfect condition after defrosting, it is important to thaw it quickly and efficiently. With defrost function, the heat reaches the food evenly and simultaneously, with no need to manually lower the power. A microwave oven defrosts by using intervals of low heat.
You can cook in two stages by manually programming the steps of the cooking process. For example, in step 1 you may opt for more microwaves than grill, in step 2 choose just grilling to achieve a final crust. When you activate this mode, the microwave oven automatically follows the steps so you don‘t have to do it manually.
