Viewing a List of AIS and MARPA Threats

1From a chart or a 3D chart view, select Menu > Other Vessels > AIS & MARPA List > Show.

2Select the type of threats to include in the list.

Setting the Safe-Zone Collision Alarm

Before you can set a collision alarm, you must have a compatible chartplotter connected to an AIS device or radar.

The safe-zone collision alarm is used only with AIS and MARPA. MARPA functionality works with radar. The safe zone is used for collision avoidance and can be customized.

1Select Settings > Alarms > AIS > Collision Alarm > On.

A message banner appears and an alarm sounds when a MARPA-tagged object or 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.

2Select Range.

3Select a distance for the safe-zone radius around your vessel.

4Select Time To.

5Select 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.

Navigating to a Distress Signal Transmission

When you receive a distress signal transmission, a distress signal alarm appears.

Select Review > Go To to begin navigation to the transmission.

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.

Enabling AIS Transmission Test Alerts

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.

1Select Settings > Alarms > AIS.

2Select 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.

Turning Off AIS Reception

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.

Navigation and Fishing Chart Setup

NOTE: Not all settings apply to all charts and 3D chart views. Some settings require external accessories or applicable premium charts.

From the Navigation chart or Fishing chart, select Menu > Chart Menu > Chart Setup.

Satellite Photos: Shows high-resolution satellite images on the land or on both land and sea portions of the Navigation chart, when certain premium maps are used (Showing Satellite Imagery on the Navigation Chart).

Tides & Currents: Shows current station indicators and tide station indicators on the chart (Showing and Configuring Tides and Currents) and enables the tides and current slider, which sets the time for which tides and currents are reported on the map.

Roses: Shows a compass rose around your boat, indicating compass direction oriented to the heading of the boat. A true wind direction or apparent wind direction indicator appears if the chartplotter is connected to a compatible marine wind sensor. When in sailing mode, true and apparent wind are shown on the wind rose.

Lake Level: Sets the present water level of the lake. This feature is available only with some premium maps.
