Unlike the Amazon Echo smart speakers, the Echo Show benefits from having a full display. But the device still uses similar light signals to its speaker counterparts, and they appear on the bottom of the screen in a thin band. Here are the color meanings:
- A solid band of blue with a cyan spot indicating the direction of the speaker will appear when you speak the wake word.
- A solid band of red means the microphone and camera have been turned off. After a few seconds, the light will turn off, leaving a microphone/camera-off symbol in the upper right hand corner of the display.
- A band of orange means your Echo Show is experiencing network connectivity issues.
- A band of violet means you have set the Echo Show to Do Not Disturb mode. After a few seconds, the light will turn off, leaving a crescent moon symbol in the upper right hand corner of the display.
