Select Settings > Alarms > System.
Alarm Clock
Sets an alarm clock.
Device Voltage: Sets an alarm to sound when the battery reaches a specified low voltage.
GPS Accuracy: Sets an alarm to sound when the GPS location accuracy falls outside the user-defined value.
Setting the Fuel Alarm
The Beeper setting must be turned on to make alarms audible
audible alarms could lead to injury or property damage.
Before you can set a fuel level alarm, you must connect a compatible fuel flow sensor to the chartplotter.
You can set an alarm to sound when the total amount of remaining onboard fuel reaches the level you specify.
1 Select Settings > Alarms > Fuel > Fuel Alarm > On.
2 Enter the remaining amount of fuel that triggers the alarm, and select Done.
Units Settings
Select Settings > Units.
System Units: Sets the unit format for the device. For example, Custom > Depth > Fathoms sets the unit format
for depth to Fathoms.
Variance: Sets the magnetic declination, the angle between magnetic north and true north, for your present
location.
North Reference: Sets the direction references used in calculating heading information. True sets geographic
north as the north reference. Grid sets grid north as the north reference (000º). Magnetic sets the magnetic
north as the north reference.
Position Format: Sets the position format in which a given location reading appears. Do not change this setting
unless you are using a map or chart that specifies a different position format.
Map Datum: Sets the coordinate system on which the map is structured. Do not change this setting unless you
are using a map or chart that specifies a different map datum.
Time: Sets the time format, time zone, and daylight saving time.
Navigation Settings
NOTE: Some settings and options require additional charts or hardware.
Select Settings > Navigation.
Route Labels: Sets the type of labels shown with route turns on the map.
Auto Guidance: Sets the parameters the chartplotter uses when calculating an Auto Guidance path, when you
are using some premium maps.
Turn Transition Activ.: Sets the turn transition to be calculated based on time or distance.
Turn Transition Time: Sets how many minutes before the turn that you transition to it as the next leg, when
Time is selected for the Turn Transition Activ. setting. You can raise this value to help improve the accuracy
of the autopilot when navigating a route or an Auto Guidance path with many frequent turns or at higher
speeds. For straighter routes or slower speeds, lowering this value can improve autopilot accuracy.
Turn Transition Dist.: Sets how far before the turn that you transition to it as the next leg, when Distance is
selected for the Turn Transition Activ. setting. You can raise this value to help improve the accuracy of the
autopilot when navigating a route or an Auto Guidance path with many frequent turns or at higher speeds. For
straighter routes or slower speeds, lowering this value can improve autopilot accuracy.
Route Start: Selects a starting point for route navigation.
