You can control the level of ultrasound that is emitted by your Cisco Webex Board. Your board uses ultrasound to detect devices in the room running the Cisco Webex app before pairing.

We recommend that you leave the ultrasound volume at the default level unless you have a particular need to adjust it. If the level is too low or has been turned off, a warning message is displayed.


Tap the name of the system at the top of the screen and then tap Settings.

If the ultrasound volume level is too low or turned off, a warning message is displayed below your board's device name. Tap the message to go straight to the advanced settings.


Tap Advanced Settings and use the slider to adjust the Ultrasound volume.
