7.3.3 Main Bang Suppression Adjustment (MBS)
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 video focusing on the center of the radar display.
Optimum adjustment allows main bang video to remain slightly on the display.
WARNING
Do not change MBS Level/Area unless absolutely
necessary.
Incorrect adjustment will result in deletion of nearby target
images and thus collisions may occur resulting in death or
serious injuries.
Procedures 1. Open the Serviceman Menu.
2. Open the MBS menu by performing the following menu operation.
9. SP/TT Initial Setup

• Turn the [RAIN] control to the minimum position (fully to the left).
• Turn the [GAIN] control to the maximum position (fully to the right).
• Turn the [SEA] control to achieve the strength with which main bang can be judged.
4. Set 20 for 2. MBS Area .
5. Adjust the value set for 1. MBS Level so that the main bang
remains slightly.
6. Adjust the value set for 2. MBS Area so that the suppression area
will match the main bang.
