Directional Array

During a call, proprietary beamforming technology steers the microphone
array toward voices in the room, canceling out sources of noise. This
provides superior intelligibility for the persons listening at the far-end of
the call. Beamforming dynamically adjusts to changes, with blue indicator
lights showing the direction of each audio beam as it detects and follows
the voices in the room.

Volume Control

Change the speaker volume using the + and - buttons on the top of the
device.

Mute Button

During a call, use the mute button on the top of the device to toggle the
microphone on or off. When muted, the light ring on the device will slowly
pulse red.
