Introduction
Set up Intelligent Proximity for content sharing
Room considerations
Room acoustics
• Rooms with hard surfaces may cause challenges due to
severe audio reflections. Acoustical treatment of meeting
rooms is always highly recommended for the best meeting
experience as well as Intelligent Proximity performance.
• Cisco recommends only one video system with Intelligent
Proximity enabled in a room. Otherwise, interference is likely
to occur, which may lead to problems with device discovery
and session maintenance.
Basic troubleshooting
Cannot detect devices with Proximity clients
• Check if the video system is in standby mode. Ultrasound is
not transmitted if the speakers (for example a TV in standby
mode) are turned off.
• Check the speaker volume. The volume control on a speaker
itself (not the volume controlled using the remote control or
Touch 10) affects the ultrasound volume. If the volume is too
low, the listening devices cannot detect the ultrasound pairing
messages.
• Some Windows laptops are not able to record sound in the
ultrasound frequency range (20 kHz-22 kHz). This can be due
to frequency limitations with the sound card, sound driver or
the internal microphone of the particular device. Refer to the
Support forum for more information.
Audio artifacts
If you can hear audio artifacts, like humming or clipping noise,
decrease the maximum ultrasound volume (Peripherals > Pairing
> Ultrasound > Volume > MaxLevel).

You can temporarily disable Proximity in a meeting from the Touch
controller. This is useful in meetings where you want to prevent
devices in the room from receiving content.
You cannot temporarily disable Proximity if using the TRC6 remote
control.
