Without heading input and not fixed heading (Gyro-free)
1. A box search pattern is started and the positions with reception of RF power are
checked for up to 10 seconds. If RX lock is detected for more than 20% of the time, the
antenna goes to Tracking.

4.2.7 Blocking zones
You can define blocking zones, i.e. No TX and RX zones by entering azimuth and elevation
angles for each blocking zone. The system’s blocking map is built up over some weeks and
shows where the actual blocking zones are. This is useful if the antenna looses the signal
frequently and you might want to check whether the blocking zones are set up correctly. To
enable a blocking zone and display it on the blocking map you must select
Active
