AIS alarms
The AIS alarms are available only when a compatible AIS device is connected to the chart
plotter.
This collision avoidance tool warns you when your boat gets too close to another vessel or
when there is a SART vessel in your AIS display range. AIS alarms are presented with the
following alarms:
● CPA alarm: Closest Point of Approach, is triggered when distance to the closest point
of approach is minor than the value set in alarm settings.
● TCPA alarm: Time to Closest Point of Approach, triggered when time to the closest
point of approach is less then specified in alarm settings.
● SART alarm.
NOTE Consider turning CPA and TCPA alarms off or settings their values to minimum
acceptable when you are approaching busy harbour entrances and rivers, otherwise they
may be triggered too often.
