……Rain/Snow Clutter Suppression RAIN …………………………
This control is used to suppress rain or snow clutter returns. Clockwise rotation of the [RAIN] control
makes the targets clearer that may be hidden among rain/snow clutter returns. Be careful not to
overlook small targets in the clutter. This control also has the effect of reducing sea clutter, so that it is
more effective to use this control together with the [SEA] control.
Rotate the control counterclockwise to the maximum in the normal condition.
When setting to in the AUTO Menu, rain/snow clutter can be
suppressed depending upon the intensity level. When setting to in the
AUTO Menu, the mode is changed into the MANUAL mode.
(Refer to page 3 - 4)
Note: It is impossible to use both the AUTO RAIN mode and the AUTO SEA mode at the
same time.
