This device complies with part 15 of the FCC Rules and Regulations. Operation is subject to the 
following two conditions: (1) This device may not cause harmful interference, and (2) This device 
must accept any interference received, including interference that may cause undesired 
operation. 
 
This equipment has been tested and found to comply with the limits for a Class B digital device, 
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection 
against harmful interference in a residential installation. This equipment generates, uses, and can 
radiate radio-frequency energy and, if not installed and used 
in accordance with these instructions, may cause harmful interference to radio communications. 
 
If this equipment does cause harmful interference to radio or television reception, which can be 
determined by turning the equipment on and off, the user is encouraged to correct the 
interference by one or more of the following measures: 

•  Increase the separation between the affected equipment and the unit; 

•  Connect the affected equipment to a power outlet on a different circuit from that which the 

receiver is connected to; 

•  Consult the dealer and/or experienced radio/TV technician for help. 

The antenna of a Cyclone 900 MHz module must be installed to provide a separation distance of at least 60 
cm (approx 24 inches) from all persons. When so installed, the module’s RF field is within Health Canada 
limits for the general population; consult Safety Code 6, obtainable from Health Canada’s website 
http://www.hc-sc.gc.ca/rpb. Per Health Canada Safety Code 6, the installer of this radio equipment must 
ensure that the antenna is located or pointed such that it does not emit RF field in excess of Health Canada 
limits for the general population.

, according to the FCC OET Bulletin 65, the ICNIRP 

guidelines, and the Health Canada Safety Code 6. The corresponding compliance distances referenced 
above have been determined by assuming worst- case scenarios. The peak power density (S) in the far-field 
of a radio-frequency source with rms transmit power P and antenna gain G at a distance d is  

 

 In the case of a 900 MHz Cyclone SM or AP with an antenna gain of 9.1 dBi (a factor of 9) and 

correctly entered in the user interface as a 9.1 dBi antenna, the peak power density equals the exposure 
limit at a distance of 18 cm. A power compliance margin of over 11 is artificially introduced by setting the 
distance to 60 cm.
