7.4.3 Main Bang Suppression Adjustment (MBS Level)
Main Bang Suppression is adjusted to suppress main bang, a reflection signal from 3D circuit including wave
guide tube, that generally appears as a circular image focusing on the center of the radar display. Optimum
adjustment allows main bang image to remain lightly on the display.
This adjustment is made for settings in the processing circuit of the display unit.

necessary.

range and cause collision, resulting in death or serious
injury.
