1 From a Radar screen, select Menu > Radar Menu > OtherVessels > AIS & MARPA List > Show.2 Select the type of threats to include in the list.Showing AIS Vessels on the Radar ScreenAIS requires the use of an external AIS device and activetransponder signals from other vessels.You can configure how other vessels appear on the Radarscreen. If any setting (except the AIS display range) isconfigured for one radar mode, the setting is applied to everyother radar mode. The details and projected heading settingsconfigured for one radar mode are applied to every other radarmode and to the Radar overlay.1 From a Radar screen or the Radar overlay, select Menu >Radar Menu > Other Vessels > Display Setup.2 Select an option:• To indicate the distance from your location within whichAIS vessels appear, select Display Range, and select adistance.• To show details about AIS-activated vessels, selectDetails > Show.• To set the projected heading time for AIS-activatedvessels, select Projected Heading, and enter the time.VRM and EBLThe variable range marker (VRM) and the electronic bearingline (EBL) measure the distance and bearing from your boat toa target object. On the Radar screen, the VRM appears as acircle that is centered on the present location of your boat, andthe EBL appears as a line that begins at the present location ofyour boat and intersects the VRM. The point of intersection isthe target of the VRM and the EBL.Showing the VRM and the EBLThe VRM and the EBL configured for one mode are applied toother radar modes.NOTE: The VRM and the EBL cannot be changed in sentrymode.From a Radar screen, select Menu > Radar Menu > ShowVRM/EBL.Adjusting the VRM and the EBLBefore you can adjust the VRM and the EBL, you must showthem on the Radar screen (Showing the VRM and the EBL).You can adjust the diameter of the VRM and the angle of theEBL, which moves the intersection point of the VRM and theEBL. The VRM and the EBL configured for one mode areapplied to all other radar modes.1 From a Radar screen, select a new location for theintersection point of the VRM and the EBL.2 Select Drop VRM/EBL.3 Select Stop Pointing.Measuring the Range and Bearing to a Target ObjectBefore you can adjust the VRM and the EBL, you must showthem on the Radar screen (Showing the VRM and the EBL).1 From a Radar screen, select the target location.2 Select Measure Distance.The range and the bearing to the target location appear inthe upper-left corner of the screen.Radar OverlayWhen you connect your chartplotter to an optional Garminmarine radar, you can use the Radar overlay to overlay radarinformation on the Navigation chart or on the Fishing chart.The Radar overlay superimposes radar information on theNavigation chart or the Fishing chart. Data appears on theRadar overlay based on the most recently used radar mode(such as Harbor, Offshore, or Sentry), and all settingsconfigurations applied to the Radar overlay are also applied tothe last-used radar mode. For example, if you use Harbor modeand then you switch to the Radar overlay, the Radar overlaywould show Harbor mode radar data. If you changed the gainsetting using the Radar overlay menu, the gain setting forHarbor mode would change automatically.Radar Overlay and Chart Data AlignmentWhen using the Radar overlay, the chartplotter aligns radar datawith chart data based on the boat heading, which is based bydefault on data from a magnetic heading sensor connectedusing a NMEA 0183 or NMEA 2000 network. If a headingsensor is not available, the boat heading is based on GPStracking data.GPS tracking data indicates the direction in which the boat ismoving, not the direction in which the boat is pointing. If theboat is drifting backward or sideways due to a current or wind,the Radar overlay may not perfectly align with the chart data.This situation should be avoided by using boat-heading datafrom an electronic compass.If the boat heading is based on data from a magnetic headingsensor or an automatic pilot, the heading data could becompromised due to incorrect setup, mechanical malfunction,magnetic interference, or other factors. If the heading data iscompromised, the Radar overlay may not align perfectly withthe chart data.Showing the Radar OverlayThe Radar overlay displays data based on the most recentlyused radar mode.From a Radar screen, select Menu > Radar Menu >Change Radar > Radar Overlay.The radar picture appears in orange and overlays theNavigation chart.Stopping the Transmission of Radar SignalsFrom a Radar screen, select Menu > Radar Menu > Radarto Standby.TIP: Press from any screen to quickly stop radartransmission.Optimizing the Radar DisplayYou can adjust the radar display settings for reduced clutter andincreased accuracy.NOTE: You can optimize the radar display for each radar mode.1 Select a radar range (Adjusting the Radar Range).2 Restore the default value of the gain setting (Adjusting Gainon the Radar Screen Automatically).3 Adjust the gain setting manually (Adjusting Gain on theRadar Screen Manually).Radar Gain and ClutterAdjusting Gain on the Radar Screen AutomaticallyThe automatic gain setting for each radar mode is optimized forthat mode, and may differ from the automatic gain setting usedfor another mode.NOTE: Depending upon the radar in use, the gain settingconfigured for use in one radar mode may or may not beapplied to other radar modes or to the Radar overlay.NOTE: Not all options and settings are available on all radarand chartplotter models.1 From a Radar screen or the Radar overlay, select Menu >Radar Menu > Gain.2 Select an available option:• Select Auto.18 Radar
