Beam Angle Selection (T-BOX Only)
Press the "Beam Angle Select / Return" button on the T-BOX touch pad.
During normal operation,
this button switches back-and-forth between the the wide 40 degree cone
and the narrow 20 degree cone.
IMPORTANT: You will need to increase the gain level while using the
wide 40 degree much more than when using the narrow 20 degree beam.
This is normal because you are covering twice as much area with the
wider beam.
