Safety messages
When AIS Safety Messages is on (controlled from the AIS Layer
Setup Menu), incoming safety messages from vessels, shore sta-
tions and mobile stations are displayed in a pop-up box. The
message will include latitude and longitude if it is available.
Whenever you receive a safety message, the system gives you
options to:
• Remove the message (ACKNOWLEDGE).
• Place a waypoint to mark the sending vessel’s position.
• GOTO the sending vessel’s position.
Note: When the simulator is operating you will not be able to
receive any safety messages.
10.7 AIS alarms
In addition to the dangerous target alarm, the system generates an
alarm when a dangerous target becomes lost (this happens if the
AIS signal from a tracked vessel is not received for more than 20
seconds).
When the connected AIS unit generates an alarm, the A-Series indi-
cates the alarm status in the data bar and displays a warning
message:
Active alarm list
The active alarm list shows the status of each local alarm. This list
can either be accessed via the AIS Layer Setup Menu (see
page 113) or from the Alarms Setup Menu (see page 132).
