Important Note on Modifications
Intentional or unintentional changes or modifications to the equipment must not be made unless under the express consent of the party
responsible for compliance. Any such modifications could void the user’s authority to operate the equipment and will void the
manufacturer’s warranty.
U.S. Federal Communication Commission (FCC) and Industry Canada (IC) Notification
This device complies with part 15 of the U. S. FCC Rules and Regulations and with RSS-210 of Industry Canada. 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 U.S. FCC
Rules and with RSS-210 of Industry Canada. 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.
FCC IDs and Industry Canada Certification Numbers are listed in the following table:

Exposure Note
The antenna of a Canopy 900 MHz module must be installed to provide a separation distance of at least 80 cm (approx 32 in) 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.
The maximum RMS power does not exceed 1W.
The applicable power density exposure limit is 10 Watt/m
2
, 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 Canopy SM or AP with an antenna gain of 10 dBi (a factor of 10) and correctly entered in the user interface
as a 10 dBi gain antenna, the peak power density equals the exposure limit at a distance of 18 cm. A power compliance margin of over
20 is artificially introduced by setting the distance to 80 cm.
Consider next the case of a 900 MHz Canopy SM or AP with a 12 dBi antenna (a factor of 15.85) set in error in the user interface as
an 8 dBi gain antenna. In this case, the peak power density equals the exposure limit at a distance of 36 cm, still giving a power
compliance margin of over 5.
The compliance distance is greatly overestimated in these cases because the far-field equation neglects the physical dimension of the
antenna, which is modeled as a point-source.
