Country and Related Settings
The unit’s Configure System window provides a selectable Country field that automatically provides the allowed
bandwidth and frequencies for the selected country.
Units sold only in the United States are pre-configured to scan and display only the outdoor frequencies permitted by the
FCC. No other Country can be configured. Units sold outside of the United States support the selection of a Country by
the professional installer.
NOTE: Non-US installers should not add an antenna system until the Country is selected, the unit is rebooted, and the
proper power level is configured. The output power level of the final channel selected by DFS scan can be found
in the Event Log.
The Dynamic Frequency Selection (DFS) feature is enabled automatically when you choose a country and band that
require it. The Transmit Power Control (TPC) feature is always available.
Click Configure > System; then select the appropriate country for your regulatory domain from the Country drop-down
box.
Continue configuring settings as desired; then click Commands> Reboot tab to save and activate the settings.
Alternatively, if you want to save the configuration settings to the flash memory but not activate the settings, use the save
config CLI command.
Dynamic Frequency Selection (DFS)
The subscriber module supports Dynamic Frequency Selection (DFS) for FCC, IC, and ETSI regulatory domains per
FCC Part 15 Rules for U-NII devices, IC RSS-210, and ETSI EN 301-893 and 302-502 regulations, respectively. These
rules and regulations require that 802.11a devices use DFS to prevent interference with radar systems and other devices
that already occupy the 5 GHz band.
