How to set a sector blank
If the antenna unit is installed near the wheelhouse, the crews are exposed to the
transmitted radio waves at an extremely close range, which can be harmful to the
human body (especially the eyes). Also, if the antenna unit is installed near the mast, its
echo appears in the radar picture. In such cases, set a sector blank to stop the
transmission within the designated range. A maximum of two sector blank areas can be
set.
