Connecting a Wireless Device to the Chartplotter

Before you can connect a wireless device to the chartplotter
wireless network, you must configure the chartplotter wireless
network (Setting Up the Wireless

Setting Alarms

Navigation Alarms

Select Settings > Alarms > Navigation.
Arrival: Sets an alarm to sound when you are within a specified
distance or time from a turn or a destination.
Anchor Drag: Sets an alarm to sound when you exceed a
specified drift distance while anchored.
Off Course: Sets an alarm to sound when you are off course by
a specified distance.

System Alarms

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

Before you can set a fuel level alarm, a compatible fuel flow
sensor must be connected to the NMEA 2000 network.
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.

Setting Weather Alarms

Before you can set weather alarms, you must have a

a GXM™ device, and have a valid weather subscription.
1
Select Settings > Alarms > Weather.
2
Turn on alarms for specific weather events.

Network).

Units Settings

Select Settings > Units.
System Units: Sets the unit format for the device.
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.
Pressure Ref. Time: Sets the reference time used to calculate
the barometer trend. The trend is indicated in the barometer
field.
Time Format: Sets a 12-hour, 24-hour, or UTC time format.
Time Zone: Sets the time zone, or allows automatic selection
based on GPS location.

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 measurements for the Safe Depth,
Safe Height, and Shoreline Distance, 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.. You can raise this
value to help improve the accuracy of the autopilot when
navigating a route or an Auto Guidance line 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.. You can raise this value to help
improve the accuracy of the autopilot when navigating a
route or an Auto Guidance line 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.

Auto Guidance Line Configurations

The Safe Depth and Safe Height settings influence how the
chartplotter calculates an Auto Guidance line. If an area has an
unknown water depth or an unknown obstacle height, the Auto
Guidance line is not calculated in that area. If an area at the
beginning or the end of an Auto Guidance line is shallower than
the safe water depth or lower than the safe obstacle height, the
Auto Guidance line is not calculated in that area. On the chart,
the course through those areas appears as a gray line. When
your boat enters one of those areas, a warning message
appears.
