I don't know which microwave oven the theme is. Generally speaking, there are two ways.

Select the grilled ribs in the smart menu of the microwave oven, then click the weight adjustment to set the weight, and click Start to start heating.

2. Click the light wave combination key for three times to select combination 2, then click the time adjustment key to set the time, and finally press the start key to start the microwave oven.
