Primary user (radar) on all enabled channels (only when DFS is enabled)

If the device detects a primary user (for example radar signals) on all enabled channels of

the WLAN interface, the LED F

is lit and

flashes. 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.
