Drag the [Rain] rain/snow clutter adjustment slider dial in Radar signal information,

the screen so as to make display easy to observe.
[Rain] (rain/snow clutter adjustment) slider
Moving the slider to the right decreases the amount of images by rain/snow clutter.
Moving the slider to the left increases the amount of images by rain/snow clutter.
The current level of rain/snow clutter suppression is indicated by the bar and a numeric value.
[Points on adjustments]
When the amount of images by rain/snow clutter is decreased, the outlines of targets hidden by images
of rain/snow will appear, but please note that small targets may be missed. Since this can also reduce
sea clutter, it is effective to use it together with the sea clutter rejection function.
Normally, set the level of rain/snow clutter suppression to 0.
