How to Reduce the Rain Clutter
The reflections from the rain or snow appear on the screen. These reflected echoes
are called “rain clutter”. When the rain clutter is strong, targets in the rain clutter are
hidden in the clutter. Reflections from the rain clutter are easily identified from true tar-
gets by their wool-like appearance.
The rain control breaks the continuous display of rain or snow reflections into a ran-
dom pattern. When the rain clutter hides the targets, adjust the rain control (automatic
or manual) to reduce the clutter.
1. Click the rain mode icon at the bottom right corner on the screen to show [MAN]
or [AUTO] as appropriate.
2. For manual adjustment, rotate the setting knob to reduce the rain clutter.
For auto mode, the setting range is -50 to 50. For manual mode, 0 to 100.
