Safety messages
When the status of the AIS Safety Messages function is set to ON in the AIS Layer
Setup Menu (see
page 274
), any incoming safety messages from surrounding
vessels, shore stations and mobile stations, are displayed in a pop-up box. If known,
the message will include the sending vessel’s position in lat/lon.
You now have the option to:
• Remove the message (ACKNOWLEDGE)
• Place a waypoint on your chart/radar to mark the sending vessel’s position.
• Select to GOTO the sending vessel’s position.
Note: When the simulator is operating you will not be able to receive any safety mes-
sages.
17.7AIS Alarms
In addition to the dangerous target alarm previously described, the system
generates an alarm when a dangerous target becomes a lost target i.e. its signal has
not been received for 20 seconds.
Your AIS receiver generates local alarms which are displayed and sounded on your
E-Series display whenever an alarm condition exists on the unit.
Local AIS alarms
When the connected AIS unit generates an alarm, your E-Series displays a local
alarm message and indicates the alarm status in the data bar icon:
Time to safe zone

is considered dangerous.
3 mins , 6 mins, 12 mins, 24 mins
