2. Thawing: The microwave oven has a special function, which can quickly thaw frozen food (frozen fish, frozen meat), but attention should be paid to the relationship between weight and time, otherwise it will be easy to thaw too much, resulting in half-baked food in the middle.
3. Light wave combination: refers to the combination of microwave and light wave (barbecue) functions.
In short, it's better to buy a microwave cookbook for reference.
