: Use this mode to monitor a relatively short range, for example, bays and
coasts where many boats and ships are running. (Importance is attached to
resolution.)
: Use this mode to monitor a relatively long range, for example, the open
sea. (Importance is attached to long-range gain.)
: Use this mode to detect small targets such as fishnets of round haul netters
hidden by sea clutter returns. (Importance is attached to sea clutter
suppression, and gain to moving targets lowers.)

are detected in stormy weather. (Importance is attached to rain / snow
clutter and sea clutter suppression, and gain slightly lowers.)
: Use this mode when only a few rain / snow clutter returns or sea clutter
returns are detected.
: 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.)
