Symbol Description

Target is activated. The target appears larger on the chart. A

green line attached to the target indicates the heading of the

target. The MMSI, speed, and direction of the vessel appear

beneath the target, if the details setting has been set to

Show. 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 chartplotter displays a

message banner asking whether the vessel should continue

to be tracked. If you discontinue vessel tracking, the lost

target symbol disappears from the chart or the 3D chart view.

Dangerous target in range. The target flashes while an alarm

sounds and a message banner appears. After the alarm has

been acknowledged, a solid red triangle with a red line

attached to it indicates the location and the heading of the

target. If the safe-zone collision alarm has been set to Off, the

target flashes, but the audible alarm does not sound and the

alarm banner does not appear. If the AIS transmission from

the vessel is lost, a message banner appears.

Dangerous target is lost. A red X indicates that the AIS

transmission from the vessel is lost, and the chartplotter

displays a message banner asking whether the vessel should

continue to be tracked. If you discontinue vessel tracking, the

lost dangerous target symbol disappears from the chart or the

3D chart view.

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.

NOTE: Vessels being tracked with the Blue Force Tracking

feature are indicated with a blue-green color regardless of their

status.

Heading and Projected Course of Activated AIS

Targets

When heading and course over ground information are provided

by an activated AIS target, the heading of the target appears on

a chart as a solid line attached to the AIS target symbol. A

heading line does not appear on a 3D chart view.

The projected course of an activated AIS target appears as a

dashed line on a chart or a 3D chart view. The length of the

projected course line is based on the value of the projected

heading setting. If an activated AIS target is not transmitting

speed information, or if the vessel is not moving, a projected

course line does not appear. Changes in the speed, course over

ground, or rate of turn information transmitted by the vessel can

impact the calculation of the projected course line.

When course over ground, heading, and rate of turn information

are provided by an activated AIS target, the projected course of

the target is calculated based on the course over ground and

the rate of turn information. The direction in which the target is

turning, which is also based on the rate of turn information, is

indicated by the direction of the barb at the end of the heading

line. The length of the barb does not change.

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.

Showing AIS Vessels on a Chart or 3D Chart View

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

> 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.

Activating a Target for an AIS Vessel

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

Select AIS Vessel > Activate Target.

Viewing Information about a Targeted AIS Vessel

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.

Deactivating a Target for an AIS Vessel

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

Select AIS Vessel > Deactivate Target.

Viewing a List of AIS Threats

From a chart or 3D chart view, select Menu > Other Vessels

> AIS List.

Setting the Safe-Zone Collision Alarm

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.

AIS Distress Signals

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.
