When course over ground and heading information are provided 

by an activated AIS target, but rate of turn information is not 

provided, the projected course of the target is calculated based 

on the course over ground information.

Before you can use AIS, you must connect the chartplotter to an 

external AIS device and receive active transponder signals from 

other vessels.
You can configure how other vessels appear on a chart or on a 

3D chart view. The display range configured for one chart or one 

3D chart view are applied only to that chart or to that 3D chart 

view. The details, projected heading, and trails settings 

configured for one chart or one 3D chart view are applied to all 

charts and to all 3D chart views.

From a chart or 3D chart view, select MENU > Other 

Vessels > AIS Display Setup.

Select an option:
• To indicate the distance from your location in which AIS 

vessels appear, select Display Range, and select a 

distance.

• To show details about AIS-activated vessels, select 

Details > Show.

• To set the projected heading time for AIS-activated 

vessels, select Proj. Heading, and enter the time.

• To show the tracks of AIS vessels, select Trails, and 

select the length of the track that appears using a trail.

From a chart or a 3D chart view, select an AIS vessel.

Select AIS Vessel > Activate Target.

You can view the AIS signal status, MMSI, GPS speed, GPS 

heading, and other information that is reported about a targeted 

AIS vessel.

From a chart or a 3D chart view, select an AIS vessel.

Select AIS Vessel.

From a chart or a 3D chart view, select an AIS vessel.

Select AIS Vessel > Deactivate Target.

From a chart or 3D chart view, select MENU > Other 

Vessels > AIS List.

Before you can set a safe-zone collision alarm, you must have a 

compatible chartplotter connected to an AIS device.
The safe-zone collision alarm is used only with AIS. The safe 

zone is used for collision avoidance, and can be customized.

Select Settings > Alarms > AIS > AIS Alarm > On.
A message banner appears and an alarm sounds when an 

AIS-activated vessel enters the safe-zone area around your 

boat. The object is also labeled as dangerous on the screen. 

When the alarm is off, the message banner and audible 

alarm are disabled, but the object is still labeled as 

dangerous on the screen.

Select Range.

Select a distance for the safe-zone radius around your 

vessel.

Select Time To.

Select a time at which the alarm will sound if a target is 

determined to intersect the safe zone.
For example, to be notified of a pending intersection 10 

minutes before it will likely occur, set Time To to 10, and the 

alarm will sound 10 minutes before the vessel intersects the 

safe zone.

Self-contained AIS distress signal devices transmit emergency 

position reports when activated. The chartplotter can receive 

signals from Search and Rescue Transmitters (SART), 

Emergency Position Indicating Radio Beacons (EPIRB), and 

other man overboard signals. Distress signal transmissions are 

different than standard AIS transmissions, so they appear 

differently on the chartplotter. Instead of tracking a distress 

signal transmission for collision avoidance, you track a distress 

signal transmission to locate and assist a vessel or person.

When you receive a distress signal transmission, a distress 

signal alarm appears.

Select Review > Go To to begin navigation to the 

transmission.

information about the transmission and begin navigation.
Transmission lost.

Transmission test. Appears when a vessel initiates a test of 
their distress signal device, and does not represent a true 
emergency.
Transmission test lost.

To avoid a large number of test alerts and symbols in crowded 

areas such as marinas, you can select to receive or ignore AIS 

test messages. To test an AIS emergency device, you must 

enable the chartplotter to receive test alerts.

Select Settings > Alarms > AIS.

Select an option:
• To receive or ignore Emergency Position Indicating Radio 

Beacon (EPRIB) test signals, select AIS-EPIRB Test.

• To receive or ignore Man Overboard (MOB) test signals, 

select AIS-MOB Test.

• To receive or ignore Search and Rescue Transponder 

(SART) test signals, select AIS-SART Test.

AIS signal reception is turned on by default.

Select Settings > Other Vessels > AIS > Off.
All AIS functionality on all charts and 3D chart views is 

disabled. This includes AIS vessel targeting and tracking, 

collision alarms that result from AIS vessel targeting and 

tracking, and the display of information about AIS vessels.
