Blanking Zone
A Blanking Zone can be used to mask the segment of the scan rotation that is obscured by the
vessel’s superstructure. The start and end of the zone can be set to any positions around the circle
to the nearest degree.
Generally, once the blanking zone has been set, it will not need to be changed. However, there
may be occasions when it is necessary to adjust the blanking zone, for example if the responder is
on the opposite side of the vessel to normal.
!
The option to change the blanking zone
is not available whilst tracking.
