8.1.1 NOISE LEVEL
Adjust the noise level.
The noise level is adjusted at the factory. When adjusting the noise level after installation, perform only fine-
tuning within ±5.
8.1.2 MAIN BANG SUPPRESSION
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.
If the main bang is not so big, use the default setting at factory.
Before adjustment:
1.Set the range to 0.125NM.
2.Set the radar video enhance function.
3.Set the radar video process function.
4.Turn the [GAIN] control to the maximum position.
5.Turn the [RAIN] control to the minimum position.
6.Turn the [SEA] control to achieve the strength with which main bang can be judged.
Do not change suppression level/area unless absolutely necessary.
Incorrect adjustment will result in deletion of nearby target images and
thus collisions may occur resulting in accidents.
