Introduction
Set up Intelligent Proximity for content sharing
Ultrasound emission
Cisco video systems emit ultrasound as part of the Proximity
feature.
Use the Proximity > Mode setting to switch the Proximity feature -
and thereby also ultrasound emission - 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.
Spark Room Kit, Spark 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.
DX70 and DX80:
• The ultrasound sound pressure level is below 75 dB at a
distance of 20 cm or more from the loudspeaker.
Codec Plus, SX10, SX20, and SX80:
• We cannot foresee the ultrasound sound pressure level on
these video systems, because they emit ultrasound on third-
party loudspeakers.
The volume control on the loudspeaker itself, and the
Peripherals > Pairing > Ultrasound > Volume > MaxLevel
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
Spark Room Kit, and Spark Room Kit Plus:
• The systems are not designed for headset use, and do not
have a dedicated headset output. We don't recommend to
connect a headset to these system.
DX70, DX80, and SX10N:
You can always use a headset with these systems because:
• 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.
Codec Plus, SX10, SX20, SX80, and MX Series:
• We strongly recommend you to switch off ultrasound emission
if you use a headset with these video systems (set
Mode to Off). Then you cannot use the Proximity feature.
Since these systems don't have dedicated headset outputs,
we are not able to control the sound pressure level from the
connected headsets.

SX10 versus SX10N
Cisco TelePresence SX10 Quick Set
comes in two versions: SX10 and SX10N.
SX10N has a built-in loudspeaker for
ultrasound, while SX10 use the same
speakers (3 rd party) for ultrasound as for
other audio signals.
Find which version you have
SX10 or SX10N is part of the following
strings:
• Check the PID field on the rating label
at the rear of the video system
• Navigate to Setup > Status
interface and check the
