BLIND SECTOR 1 and BLIND SECTOR 2
Set area (up to 2) where no radar pulses will be transmitted, and the heading should be

display. To enter an area, enter start bearing relative the heading and dead sector angle. To
erase the area, enter 0 for both the START and ANGLE sections. The setting range of
START is 0 to 359
