y The following 12 modes are provided:
Standard: Use this mode for general purpose. This is suitable to monitor a
relatively short range.
Coast: 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.)
Deepsea: Use this mode to monitor a relatively long range, for example, the
open sea.
(Importance is attached to long-range sensitivity.)
Fishnet: 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 sensitivity 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 sensitivity
slightly lowers.)
