Industry Canada Guidelines for Exposure to Radio Waves 
The Xirrus Arrays 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. 
Minimum Separation Distance 
Health Canada states 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 you can easily do so by reorienting antennas away from the 
user, placing the antennas at a greater separation distance than recommended, or lowering the 
transmitter power output.
