The fourth button on the Amazon Echo will turn off the microphone, and is in the 9 o’clock position.
There are still four buttons on the top, and the mic off button is still in the 9 o’clock position.
Turning the microphone off is the same routine as with the Echo and Echo Dot.
Like the Echo Dot and Echo Plus, it’s a round button with a line through it, and it’s at the top in the center.
Look to the far left if the Echo Show is facing you for the button of a circle with a line through it and press it.
