BLIND SECTOR 1 and BLIND SECTOR 2
Set area (up to 2) where no radar pulses will be transmitted, and heading should be
adjusted before setting any blind sector. For example, set the area where an interfering
object at the rear of the scanner would produce a dead sector (area where no echoes
appear) on the 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° and ANGLE is 0 to 180°.
ANT REVOLUTION
