XR520H Quick Installation Guide
antenna gain minus cable loss. A minimum separation distance of 23.2 cm between the antenna
and all persons is required during normal operation.
Only antennas provided by Xirrus for use with the product should be installed. The use of any
other antennas may cause damage to the access points or violate regulatory emission limits and
will not be supported by Xirrus.
International Guidelines for Exposure to Radio Waves
The Xirrus Access Points include radio transmitters and receivers. It is designed not to exceed
the limits for exposure to radio waves (radio frequency electromagnetic fields) recommended
by international guidelines. The guidelines were developed by an independent scientific
organization (ICNIRP) and include a substantial safety margin designed to ensure the safety of
all persons, regardless of age and health.
As such the systems are designed to be operated as to avoid contact with the antennas by the
end user. It is recommended to set the system in a location where the antennas can remain at
least a minimum distance as specified from the user in accordance to the regulatory guidelines
which are designed to reduce the overall exposure of the user or operator.

The World Health Organization has stated that present scientific information does not indicate
the need for any special precautions for the use of wireless devices. They recommend that if you
are interested in further reducing your exposure then you can easily do so by reorienting
antennas away from the user or placing the antennas at a greater separation distance then
recommended.
FCC Guidelines for Exposure to Radio Waves
The device includes a radio transmitter and receiver. It is designed not to exceed the limits for
exposure to radio waves (radio frequency electromagnetic fields) as referenced in FCC Part
1.1310. The guidelines are based on IEEE ANSI C 95.1 (92) and include a substantial safety
margin designed to ensure the safety of all persons, regardless of age and health.
As such the systems are designed to be operated as to avoid contact with the antennas by the
end user. It is recommended to set the system in a location where the antennas can remain at
least a minimum distance as specified from the user in accordance to the regulatory guidelines
which are designed to reduce the overall exposure of the user or operator.
