Primary user (radar) on all enabled channels
If the device detects a primary user (for example radar signals) on all enabled channels of
the WLAN interface, the LED F

flashes. No data traffic is then possible for the
next 30 minutes. After this time, the device runs the scan again and c
hecks 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.
