coasts where many boats and ships are running. (Importance is attached to
resolution.)
Deepsea : Use this mode to monitor a relatively long range, for example, the open
sea. (Importance is attached to long-range gain.)

hidden by sea clutter returns. (Importance is attached to sea clutter
suppression, and gain to moving targets lowers.)
Storm : Use this mode when many rain / snow clutter returns or sea clutter returns
are detected in stormy weather. (Importance is attached to rain / snow
clutter and sea clutter suppression, and gain slightly lowers.)
Calm : Use this mode when only a few rain / snow clutter returns or sea clutter
returns are detected.
Rain : Use this mode when sea clutter is not strong but rain / snow clutter is strong.
(Importance is attached to rain / snow clutter suppression, and gain slightly
lowers.)
Bird : Use this mode to detect flocks of sea birds.
Long : Use this mode to monitor utmost distances in the broad ocean.
Buoy : Use this mode to detect small targets like radio buoys in areas outside the
sea clutter area. (This mode displays targets of which detection probability
is low.)
