A primary user was found on all enabled channels.
Note
Primary user (radar) on all enabled channels
If the device detects a primary user on all enabled channels (for example radio waves of a
radar station), the LEDs F
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 resetting the device.
