Initiate Track
The tracked target is regarded as an object, and it is identified with a circle and two
lines. The two lines reflect the size of the current tracking area. By default, a new
manually initiated tracked object is automatically given priority status. The bearing line
is automatically locked on the object to reflects its bearing.
Note
If you change the tilt or bearing settings manually the priority status is lost. The SN90
system will still attempt to track the target, but the tilt and bearing settings are not
adjusted.
The priority is identified with a "P". You can only give priority status to one object. If
you start tracking a new target the first target will loose its priority. The same applies
if you give priority to another marker. The tracking of the first target will however not
stop, and the target marker is still shown.
Relevant information about the tracked object can be found in the bottom left corner of
the view. To read this information in the view's bottom left corner, you must enable it on
