The RAIN control is used to reduce the clutter echo appearing on the screen caused

RAIN control can be switched to either a manual or auto mode by pressing the RAIN
control knob.
The control mode toggles each time you press the control. When first turned on, the
anti-clutter RAIN function is defaulted to manual mode. To set the auto RAIN-clutter
control, press the control knob. The clutter echo from rain or snow will be reduced
automatically and the manual rain clutter control will become inactive.
