When pressed, there’s no need to say “Alexa” or “microwave.” To start cooking, use your voice or just press the Ask Alexa button and say your cook time. The button will instantly wake up your paired Echo, just like saying “Alexa” does. For example, press the Ask Alexa button and say, “2 minutes,” or “frozen vegetables.” Fire TV, Fire Tablets, Echo Look, and Amazon Tap devices are not supported with the Ask Alexa button.
