1, press 1 light wave/combination key (pure light wave) to use a metal baking tray, which can be placed at the bottom of the microwave oven or on the grill.

2. Combination 1: Press twice (indicating that the light wave ratio is higher than the microwave ratio), and the metal baking tray can be used at the bottom of the microwave oven, but not on the grill.

3. Combination 2: Press 3 times (indicating that the light wave ratio is less than the microwave ratio), you can use a high-temperature resistant tempered glass plate or silicone mold, but you can't use a metal baking tray!
