XR520H Quick Installation Guide
The US Food and Drug Administration has stated that present scientific information does not
indicate the need for any special precautions for the use of wireless devices. The FCC
recommends 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 or lowering the transmitter power output.
Industry Canada 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) as referenced in
Health Canada Safety Code 6. The guidelines include a substantial safety margin designed into
the limit 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.
