How to Reduce
Rain Clutter
The antenna picks up rain
clutter (rain, snow, or hail) in
the same manner as normal
targets, as in the right fig-
ure. When rain clutter
masks targets, use the
[Rain] control to reduce the
clutter. The higher the setting the greater the
reduction of rain clutter
To adjust the rain clutter, open the menu then
tap the (
) icon. Select the [Rain] screen.
Tap the [Manual] or [Auto] button. For manual
adjustment, drag the slider bar to reduce the
rain clutter.
