The informationreported for each vessel includes the Maritime MobileService Identity (MMSI), location, GPS speed, GPS heading,time that has elapsed since the last position of the vesselwas reported, nearest approach, and time to the nearestapproach.AIS Targeting SymbolsSymbol DescriptionAIS vessel. The vessel is reporting AIS information. Thedirection in which the triangle is pointing indicates thedirection in which the AIS vessel is moving.Target is selected.Target is activated. The target appears larger on thechart. A green line attached to the target indicates theheading of the target. The MMSI, speed, and direction ofthe vessel appear beneath the target, if the details settinghas been set to Show. If the AIS transmission from thevessel is lost, a message banner appears.Target is lost. A green X indicates that the AIStransmission from the vessel is lost, and the chartplotterdisplays a message banner asking whether the vesselshould continue to be tracked. If you discontinue vesseltracking, the lost target symbol disappears from the chartor the 3D chart view.4 Charts and 3D Chart ViewsDRAFT
Symbol DescriptionDangerous target in range. The target flashes while analarm sounds and a message banner appears. After thealarm has been acknowledged, a solid red triangle with ared line attached to it indicates the location and theheading of the target. If the safe-zone collision alarm hasbeen set to Off, the target flashes, but the audible alarmdoes not sound and the alarm banner does not appear. Ifthe AIS transmission from the vessel is lost, a messagebanner appears.Dangerous target is lost. A red X indicates that the AIStransmission from the vessel is lost, and the chartplotterdisplays a message banner asking whether the vesselshould continue to be tracked. If you discontinue vesseltracking, the lost dangerous target symbol disappearsfrom the chart or the 3D chart view.The location of this symbol indicates the closest point ofapproach to a dangerous target, and the numbers nearthe symbol indicate the time to the closest point ofapproach to that target.Heading and Projected Course of Activated AISTargetsWhen heading and course over ground information areprovided by an activated AIS target, the heading of the targetappears on a chart as a solid line attached to the AIS targetsymbol. A heading line does not appear on a 3D chart view.The projected course of an activated AIS target appears as adashed line on a chart or a 3D chart view. The length of theprojected course line is based on the value of the projectedheading setting. If an activated AIS target is not transmittingspeed information, or if the vessel is not moving, a projectedcourse line does not appear. Changes in the speed, courseover ground, or rate of turn information transmitted by thevessel can impact the calculation of the projected course line.When course over ground, heading, and rate of turninformation are provided by an activated AIS target, theprojected course of the target is calculated based on thecourse over ground and the rate of turn information. Thedirection in which the target is turning, which is also based onthe rate of turn information, is indicated by the direction of thebarb at the end of the heading line. The length of the barbdoes not change.When course over ground and heading information areprovided by an activated AIS target, but rate of turninformation is not provided, the projected course of the targetis calculated based on the course over ground information.Showing AIS Vessels on a Chart or 3D Chart ViewBefore you can use AIS, you must connect the chartplotter toan external AIS device and receive active transpondersignals from other vessels.You can configure how other vessels appear on a chart or ona 3D chart view. The display range configured for one chartor one 3D chart view are applied only to that chart or to that3D chart view. The details, projected heading, and trailssettings configured for one chart or one 3D chart view areapplied to all charts and to all 3D chart views.1From a chart or 3D chart view, select Menu > OtherVessels > AIS Display Setup.2Select an option:• To indicate the distance from your location in whichAIS vessels appear, select Display Range, andselect a distance.• To show details about AIS-activated vessels, selectDetails > Show.• To set the projected heading time for AIS-activatedvessels, select Projected Heading, and enter thetime.• To show the tracks of AIS vessels, select Trails, andselect the length of the track that appears using atrail.Activating a Target for an AIS Vessel1From a chart or a 3D chart view, select an AIS vessel.2Select AIS Vessel > Activate Target.Viewing Information about a Targeted AIS VesselYou can view the AIS signal status, MMSI, GPS speed, GPSheading, and other information that is reported about atargeted AIS vessel.1From a chart or a 3D chart view, select an AIS vessel.2Select AIS Vessel.Deactivating a Target for an AIS Vessel1From a chart or a 3D chart view, select an AIS vessel.2Select AIS Vessel > Deactivate.Viewing a List of AIS ThreatsFrom a chart or 3D chart view, select Menu > OtherVessels > AIS List.Setting a Safe-Zone Collision AlarmBefore you can set a collision alarm, you must have acompatible chartplotter connected to an AIS device or radar.The safe-zone collision alarm is used only with AIS. The safezone is used for collision avoidance and can be customized.1Select Alarms > AIS > AIS Alarm > On.A message banner appears and an alarm sounds whenan AIS-activated vessel enters the safe-zone area aroundyour boat. The object is also labeled as dangerous on thescreen. When the alarm is off, the message banner andaudible alarm are disabled, but the object is still labeledas dangerous on the screen.2Select Range.3Select a distance for the safe-zone radius around yourvessel.4Select Time To.5Select a time at which the alarm will sound if a target isdetermined to intersect the safe zone.For example, to be notified of a pending intersection 10minutes before it will likely occur, set Time To to 10, andthe alarm will sound 10 minutes before the vesselintersects the safe zone.AIS Search and Rescue TransmittersAIS Search and Rescue Transmitters (AIS-SART, or SART)are self-contained devices that transmit emergency positionreports when activated. SART transmissions are differentthan standard AIS transmissions, so they appear differentlyon the chartplotter. Instead of tracking a SART transmissionfor collision avoidance, you track a SART transmission tolocate and assist a vessel.Charts and 3D Chart Views 5DRAFT

Beforebeginning radar transmission, verify that the area around theradar is clear. The radar transmits a beam approximately 12°above and below a line extending horizontally from the centerof the radar. Avoid looking directly at the radar, because theeyes are the most susceptible parts of the body.When you connect your chartplotter to an optional Garminmarine radar, such as a GMR 1206 xHD or a GMR 24 HD,you can view more information about your surroundings.The GMR transmits a narrow beam of microwave energy as itrotates to a 360° pattern. When the transmitted energycontacts a target, some of that energy is reflected back to theradar.Radar Display ModesNOTE: Not all modes are available with all radar devices andall chartplotters.Select Radar, and select a mode.Cruising Mode: Shows a full-screen image of the gatheredradar information.Harbor Mode: Intended for use in inland waters, this modeworks best with short-range signals (2 nm or less).Offshore Mode: Intended for use in open waters, this modeworks best with long-range signals.Sentry Mode: Allows you to put the radar into timed-transmitmode, in which you can configure a radar transmit andstandby cycle to conserve power. You can also enable aguard zone in Sentry mode, which identifies a safe zonearound your boat. If you switch from Sentry mode toanother mode, the radar switches to full-time transmissionand disables all guard zones.Radar Overlay Mode: Shows a full-screen image of thegathered radar information on top of the Navigation chart.The Radar overlay displays data based on the most-recently used radar mode.Transmitting Radar SignalsNOTE: As a safety feature, the radar enters standby modeafter it warms up.

Adjusting the Zoom Scale on the RadarScreenThe radar zoom scale, also called the radar signal range,represents the distance from your position (the center) to theoutermost ring.From a Radar screen, select or .Each ring represents an even division of the zoom scale.For example, if the zoom scale is set at 3 miles, each ringrepresents 1 mile from the center out.Tips for Selecting a Radar Zoom ScaleThe radar zoom scale, or radar signal range, indicates thelength of the pulsed signal transmitted and received by theradar. As the range increases, the radar transmits longerpulses in order to reach distant targets. Closer targets,especially rain and waves, also reflect the longer pulses,which can add noise to the Radar screen. Viewinginformation about longer-range targets can also decrease theamount of space available on the Radar screen for viewinginformation about shorter-range targets.• Determine what information you need to see on theRadar screen.For example, do you need information about nearbyweather conditions or targets and traffic, or are you moreconcerned about distant weather conditions?• Assess the environmental conditions where the radar isbeing used.Especially in inclement weather, longer-range radarsignals can increase the clutter on the Radar screen andmake it more difficult to view information about shorter-range targets. In rain, shorter-range radar signals canenable you to view information about nearby objects moreeffectively, if the rain clutter setting is configuredoptimally.• Select the shortest effective range, given your reason forusing radar and the present environmental conditions.Sentry ModeSentry mode allows you to put the radar into timed-transmitmode, in which you can configure a radar transmit andstandby cycle to conserve power. You can also enable aguard zone in this mode, which identifies a safe zone aroundyour boat and sounds an alarm when a radar object entersthe zone. Sentry mode works with all Garmin GMR modelradars.Enabling Timed TransmitSelect Radar > Sentry > Menu > Set Up Sentry >Timed Xmit > On.Setting the Standby and Transmit TimesBefore you can set the standby and transmit times, you mustenable timed transmit (page 17).To help conserve power, you can indicate the radar standbytime and the transmit time to implement periodic radar signaltransmissions at set intervals.1Select Radar > Sentry > Menu > Set Up Sentry.2Select Stdby Time.3Enter the time interval between radar signaltransmissions.4Select Xmit Time.5Enter the duration of each radar signal transmission.Enabling a Guard ZoneSelect Radar > Sentry > Menu > Set Up Sentry >Enable Guard Zone.Defining a Circular Guard ZoneBefore you can define the boundaries of the guard zone, youmust enable a guard zone (page 17).You can define a circular guard zone that completelyencompasses your boat.1Select Radar > Sentry > Menu > Set Up Sentry >Adjust Guard Zone > Move Radar Guard Zone >Circle.2Select the location of the outer guard zone circle.3Select the location of the inner guard zone circle to definethe width of the guard zone.Defining a Partial Guard ZoneYou can define the boundaries of a guard zone that does notcompletely encompass your boat.1Select Radar > Sentry > Menu > Set Up Sentry >Adjust Guard Zone > Move Radar Guard Zone >Corner 1.2Touch and drag the location of the outer guard-zonecorner À.3Select Corner 2.4Touch the location of the inner guard-zone corner Á todefine the width of the guard zone.Marking a Waypoint on the Radar Screen1From a Radar screen or the Radar overlay, select alocation.2Select Create Waypoint.Viewing a List of AIS ThreatsFrom any Radar screen or the Radar overlay, you can viewand customize the appearance of a list of AIS threats.From a Radar screen or the Radar overlay, select Menu> Other Vessels > AIS 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.

The VRM and the EBL configured for one mode areapplied to all other radar modes.1From a Radar screen, select a new location for theintersection point of the VRM and the EBL.2Select Drop VRM/BLE.3Select Stop Pointing.Measuring the Range and Bearing to a TargetObjectBefore you can adjust the VRM and the EBL, you must showthem on the Radar screen (page 18).1From a Radar screen, select the target location.2Select Measure DistanceThe 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(Cruising, Harbor, Offshore, or Sentry), and all settingsconfigurations applied to the Radar overlay are also appliedto the last-used radar mode. For example, if you use Harbormode and then you switch to the Radar overlay, the Radaroverlay would show Harbor mode radar data. If you changedthe gain setting using the Radar overlay menu, the gainsetting for Harbor mode would change automatically.Radar Overlay and Chart Data AlignmentWhen using the Radar overlay, the chartplotter aligns radardata with chart data based on the boat heading, which isbased by default on data from a magnetic heading sensorconnected using a NMEA 0183 or NMEA 2000 network. If aheading sensor is not available, the boat heading is based onGPS tracking 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 orwind, the Radar overlay may not perfectly align with the chartdata. This situation should be avoided by using boat-headingdata from 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.Select Radar > Radar Overlay.The radar picture appears in orange and overlays theNavigation chart.Stopping the Transmission of RadarSignalsFrom the Radar screen, select Menu > Radar toStandby.Optimizing the Radar DisplayYou can adjust the radar display settings for reduced clutterand increased accuracy.NOTE: You can optimize the radar display for each radarmode.1Select a radar range (page 18).2Restore the default value of the gain setting (page 18).3Adjust the gain setting manually (page 19).Range of Radar SignalsThe range of the radar signal indicates the length of thepulsed signal transmitted and received by the radar. As therange increases, the radar transmits longer pulses in order toreach distant targets. Closer targets, especially rain andwaves, also reflect the longer pulses, which can add noise tothe Radar screen. Viewing information about longer-rangetargets can also decrease the amount of space available onthe Radar screen for viewing information about shorter-rangetargets.Radar Gain and ClutterAutomatically Adjusting Gain on the Radar ScreenAuto is the default value for the gain setting. The automaticgain setting for each Radar mode is optimized for that mode,and may differ from the automatic gain setting used foranother 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.From a Radar screen or the Radar overlay, select Menu> Gain > Auto.The chartplotter sets the gain automatically once, basedon average conditions, the range of the radar signal, andthe selected radar mode.

Forstraighter routes or slower speeds, lowering this valuecan improve autopilot accuracy.Route Start: Selects a starting point for route navigation.Auto Guidance Line Configurations CAUTIONThe Safe Depth and Safe Height settings influence how thechartplotter calculates an Auto Guidance line. If an area hasan unknown water depth or an unknown obstacle height, theAuto Guidance line is not calculated in that area. If an area atthe beginning or the end of an Auto Guidance line isshallower than the safe water depth or lower than the safeobstacle height, the Auto Guidance line is not calculated inthat area. On the chart, the course through those areasappears as a gray line. When your boat enters one of thoseareas, a warning message appears.NOTE: Auto Guidance is available with premium charts, insome areas.You can set the parameters the chartplotter uses whencalculating an Auto Guidance line.Safe Depth: Sets the minimum depth (chart depth datum) thechartplotter uses when calculating an Auto Guidance line.Safe Height: Sets the minimum height (chart height datum)of a bridge that your boat can safely travel under.Shoreline Distance: Sets how close to the shore you wantthe Auto Guidance line to be placed. The Auto Guidanceline may move if you change this setting while navigating.The available values for this setting are relative, notabsolute. To ensure that the Auto Guidance line is placedthe appropriate distance from shore, you can assess theplacement of the Auto Guidance line using one or morefamiliar destinations that require navigation through anarrow waterway (page 29).Adjusting the Distance from Shore CAUTIONThe Auto Guidance feature is based on electronic chartinformation. That data does not ensure obstacle and bottomclearance. Carefully compare the course to all visualsightings, and avoid any land, shallow water, or otherobstacles that may be in your path.NOTE: Auto Guidance is available with premium charts, insome areas.The Shoreline Distance setting indicates how close to theshore you want the Auto Guidance line to be placed. TheAuto Guidance line may move if you change this setting whilenavigating. The available values for the Shoreline Distancesetting are relative, not absolute. To ensure the AutoGuidance line is placed the appropriate distance from shore,you can assess the placement of the Auto Guidance lineusing one or more familiar destinations that requirenavigation through a narrow waterway.1Dock your vessel or drop the anchor.2Select Settings > Navigation > Auto Guidance >Shoreline Distance > Normal.3Select a destination that you have navigated topreviously.4Select Navigate To > Guide To.Device Configuration 29DRAFT
