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, India, Russia, Indonesia
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 5.4 GHz 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 10 on page 41 on the AP's and BHM's Carrier
Frequency pop-up and on the SM's and BHS's Frequency Scan Selection List.
Table 18 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.
