4.4.1 Background and Operation
The modules use region-specific DFS based on the “Region Code” selected on the module’s
“Configuration => General” page. By directing installers and technicians to set the Region Code
correctly, the operator gains confidence the module is operating according to national or regional
regulations without having to deal with the details for each region.
Available “Region Codes” include Other, United States, Canada, Europe, Brazil, Russia, and
Australia. Operators in regions or countries not listed and with requirements aligned with one of
the listed countries should set the Region Code to that country. Operators in regions or countries
with no requirements for DFS should use the “Other” Region Code.
New APs and BHMs from the factory will show a Region Code of “None”, and will not transmit
until the Region Code is set to a value other than “None”.
Canada, United States and Europe have requirements to avoid certain frequencies used by some
weather radar. To meet this requirement, modules set to a Region Code of Canada, United
States or Europe will display the center channel frequencies shown in Table 9 on page 28 on the
AP’s and BHM’s Carrier Frequency pop-up and on the SM’s and BHS’s Frequency Scan
Selection List.
Table 12 shows the details of DFS operation and channels available for each Region Code,
including whether DFS is active on the AP/BHM, SM/BHS, which DFS regulation apply, and any
channel restrictions. DFS does not apply to 4.9 GHz.

1. In all cases set the Region Code to the region you are in and the equipment will
provide DFS consistent with that region’s regulations. For countries or regions
not listed, use a Region Code that provides DFS functionality and channels
