CPA alarm –
target speed
The speed (in knots) which the target must be
moving in order to trigger a CPA alarm. If the target
is moving at less than this speed then no CPA alarm
will be triggered for this target.
This allows you to suppress alarms for targets which
are either stationary (anchored or moored) or are
moving very slowly (drifting, fishing, etc.).
CPA alarm –
your speed
The speed (in knots) that your own vessel must be
moving in order to allow CPA alarms. If your vessel
is moving at less than this speed then no CPA
alarms will be triggered for any targets.
This allows you to suppress alarms when your
vessel is anchored, moored, drifting, fishing, etc. It
can be used to turn off alarms automatically when
you stop or slow down and eliminates the need to
turn the
AIS
WatchMate
off or select the Anchored
profile.
Important note: CPA alarms are not triggered if GPS
information is not available for your vessel.
Profiles
To organize the filter and alarm settings there are four “profiles”.
These allow you to quickly switch between various settings when
your situation changes. This is done by selecting the active profile
from the main menu on the situation display. Each profile is provided
with a default value for its settings, but you can change these values
and they will remain at your selected settings until you change them
