Note
Primary user (radar) on all enabled channels (only when DFS is enabled)
If the device detects competing radar signals on all enabled channels of the WLAN
interface, the F LED is lit and R1 flash. No data traffic is then possible for the next 30
minutes. After this time, the device runs the scan again and checks whether a primary
user still exists. If no primary user is detected, data traffic is possible again.
The wait time of 30 minutes is necessary due to legal requirements and cannot be
shortened even by restarting the device.
