Configuring the Chartplotter
To adjust the Keel Offset:
1.From the Home screen, select Configure > My Boat > Keel Offset.
2.Use the ROCKER (GPSMAP 4000 series) or the screen keyboard (GPSMAP 5000 series) to specify the offset.
3.Select Done to accept the number.
Note: Select Cancel to cancel your changes and return to the My Boat screen.
Transducer—select sonar-cone angles, and calibrate water speed.
•Sonar Cone Angles—when using a transducer other than the standard Garmin transducer, you can set the angle, in degrees, of the sonar cone so that it is accurately depicted on the Fish Eye 3D screen. Select either 200kHz or 50kHz and use the on-screen keyboard to enter the angle.
Note: The Sonar Cone Angles setting is preset to match the cone angle of a standard Garmin dual- frequency transducer. Use this option to match the specifications of a non-standard transducer.
•Calibrate Water Speed—use this menu to calibrate a speed-sensing device. Follow the on- screen directions for calibration. If you do not have a speed-sensing device, this menu does not appear.
Note: If the boat is not moving fast enough or the speed sensor is not registering a speed, a “Speed Too Low” message appears. Select OK and safely increase boat speed. If you get the message again, stop the boat and make sure the speed-sensor wheel is not stuck. If the wheel turns freely, check the cable connections. If you continue to get the message, contact Garmin Product Support.
Configuring Other Boats
To configure settings for boats other than your own, from the Home screen, select Configure > Other Boats.
AIS—turn AIS (Automatic Identification System) on or off. AIS alerts you to area traffic by providing boat IDs, position, course, and speed for boats that are within range and equipped with a transponder.
DSC—turn DSC (Digital Selective Calling) on or off.
NOTE: To configure AIS or DSC information for other boats, your unit must be connected to an external AIS or DSC device.
Safe Zone—(AIS and MARPA only) turn a safe zone around your boat on or off. This is used for collision avoidance, and can be customized.
To customize safe-zone settings:
From the Home screen, select Configure > Other Boats > Safe Zone > Setup.
•Ring—show or hide a ring on the Navigation chart showing the safe zone for your boat.
•Range—change the measured radius of the safe zone ring to a specified distance from 0.1 to
2.0 nm (or from 0.2 to 5.0 km, or from 0.1 to 2.0 mi).
•Time to (Safe Zone)—sounds an alarm if AIS or MARPA determines that a target will intersect the Safe Zone within the defined time interval (ranging from 3 to 24 minutes).
Details—show or hide the name, speed, and bearing of AIS or MARPA targets onscreen. The details appear next to the AIS or MARPA target icon.
