5. Operating Instructions
5.1 Basic Microwave Operation
To cook with microwave function, place food in a microwave-safe container on the glass turntable. Close the door firmly. Use the control panel to set cooking time and power level.
5.2 Convection Crisper Function (Air Fryer)
The MicroCrisp features an integrated convection crisper for air frying. This function uses circulating hot air to cook food, providing crispy results similar to a dedicated air fryer. It is ideal for items like fries, chicken, and other foods that benefit from a crispy exterior.
