CHAPTER 3 MENU AND SETTINGS 54
3.8.2 AIS
With the Automatic Identification System (AIS), the device identifies and tracks other
vessels, and alerts you to area traffic. The device shows AIS information about vessels
within range equipped with a transponder, and are actively transmitting AIS information.
Targets are indicated on the display with targeting symbols.
Symbol Description
AIS vessel. The vessel is reporting AIS information. The direction of the
triangle indicates the direction the AIS vessel is moving.
Selected target.
Activated target. The target appears larger on the chart. A green line
attached to the triangle indicates the heading of the target. The MMSI, speed,
and direction of the vessel appear beneath the target if Details is turned on.
If the AIS transmission from the vessel is lost, a message banner appears.
Target is lost. A green X indicates that the AIS transmission from the vessel
is lost, and the device displays a message asking whether the vessel should
continue to be tracked. If you discontinue vessel tracking, the lost target
symbol disappears from the chart.
Dangerous target in range. The target flashes while an alarm sounds and a
message appears. A red line attached to the triangle indicates the heading
of the target. If Collision Alarm is off, the target flashes, but the audible
alarm does not sound and the alarm message does not appear. If the AIS
transmission from the vessel is lost, a message appears.
Lost dangerous target. A red X indicates that the AIS transmission from the
vessel is lost, and the device displays a message asking whether the vessel
should continue to be tracked. If you discontinue vessel tracking, the lost
dangerous target symbol disappears from the chart.
The location of this symbol indicates the closest point of approach to a
dangerous target, and the numbers near the symbol indicate the time to the
closest point of approach to that target.
Select AIS to toggle AIS tracking on/off.
CAUTION
If turned off, all AIS functionality, including AIS vessel targeting and tracking, collision
alarms from AIS vessels, and the display of information about AIS vessels, will be
disabled.
