Introduction
Set up Intelligent Proximity for content sharing
Ultrasound emission
Cisco video conferencing devices emit ultrasound pairing
messages as part of the Proximity feature.
Use the Proximity > Mode setting to switch the Proximity feature
- and thereby also emission of ultrasound pairing messages - On
and Off.
Most people are exposed to ultrasound more or less daily in many
environments, including industry, commercial applications and
home appliances.
Even if airborne ultrasound may cause subjective effects for some
individuals, it is very unlikely that any effects will occur for levels
below 75 dB.
Room 70, Room 70 G2, Room Panorama, Room 70 Panorama,
Room 55, Room 55 Dual, Room Kit, Room Kit Mini, Room Kit Plus,
SX10N and MX Series:
• The ultrasound sound pressure level is below 75 dB at a
distance of 50 cm or more from the loudspeaker.
Desk Pro, DX70, and DX80:
• The ultrasound sound pressure level is below 75 dB at a
distance of 20 cm or more from the loudspeaker.
Boards:
• The ultrasound sound pressure level is below 75 dB at a
distance of 20 cm or more from the screen.
For Board 50 and 70 (not S Series) the level can be slightly
higher right below the screen due to the downward-facing
loudspeakers.
Codec Plus, Codec Pro, SX10, SX20, and SX80:
• We cannot foresee the ultrasound sound pressure level
on these video conferencing devices, because they emit
ultrasound on third-party loudspeakers.
The volume control on the loudspeaker itself, and the
Ultrasound > MaxVolume setting affect the ultrasound sound
pressure level; the volume control on the remote control or
Touch controller does not have any effect.

Configuration Configuration Peripherals
Headsets
Desk Pro, DX70, DX80, and SX10N:
You can always use a headset with these devices because:
• Desk Pro, DX70 and DX80 have dedicated headset outputs,
on which we never emit ultrasound.
• SX10N plays ultrasound on the built-in loudspeakers.
Ultrasound is never emitted on the HDMI or audio outputs.
Room 70, Room 70 G2, Room Panorama, Room 70 Panorama,
Room 55 Dual, Room Kit Plus, Codec Plus, Codec Pro, Boards,
SX10, SX20, SX80, and MX Series:
• These devices are not designed for headset use.
• We strongly recommend you to switch off ultrasound emission
if you use a headset with these video conferencing devices
(set Proximity > Mode
Proximity feature.
• Since these devices don't have dedicated headset outputs,
we are not able to control the sound pressure level from the
connected headsets.
Room 55, Room Kit, Room Kit Mini:
• You can always connect a headset to the USB output of these
devices, because we don't emit ultrasound on this output.
• The audio line outputs (mini-jack) of the Room 55 and Room
Kit are not designed for headset use. We are not able to
control the sound pressure level from a headset that is
connected to one of these outputs..
If you connect a headset to an audio line output, we strongly
recommend you to switch off ultrasound emission (set
Proximity > Mode
