A message banner appears and an alarm sounds when
an AIS-activated vessel enters the safe-zone area around
your boat. The object is also labeled as dangerous on the
screen. When the alarm is off, the message banner and
audible alarm are disabled, but the object is still labeled
as dangerous on the screen.
2
Select Range.
3
Select a distance for the safe-zone radius around your
vessel.
4
Select Time To.
5
Select a time at which the alarm will sound if a target is
determined to intersect the safe zone.
Units Settings
Select Settings > Units.
System Units: Sets the unit format for the device.
Heading: Sets the direction references used in calculating
heading information. Auto Mag Var (automatic magnetic
variation) sets the magnetic declination for your location
automatically. True sets true north as the heading
reference. Grid sets grid north as the heading reference
(000º). User Mag Var allows you to enter the magnetic
variation value manually.
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 Reference 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 Activation: 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 Activation. 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 Distance: Sets how far before the turn that
you transition to it as the next leg, when Distance is
selected for the Turn Transition Activation. 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
 CAUTION
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.
NOTE: Auto Guidance is available with premium charts, in
some areas.
You can set the parameters the chartplotter uses when
calculating an Auto Guidance line.
Safe Depth: Sets the minimum depth (chart depth datum) the
chartplotter 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 want
the Auto Guidance line to be placed. The Auto Guidance
line may move if you change this setting while navigating.
The available values for this setting are relative, not
absolute. To ensure that the Auto Guidance line is placed
the appropriate distance from shore, you can assess the
placement of the Auto Guidance line using one or more
familiar destinations that require navigation through a
narrow waterway (page 29).
Adjusting the Distance from Shore
 CAUTION
The Auto Guidance feature is based on electronic chart
information. That data does not ensure obstacle and bottom
clearance. Carefully compare the course to all visual
sightings, and avoid any land, shallow water, or other
obstacles that may be in your path.
NOTE: Auto Guidance is available with premium charts, in
some areas.
The Shoreline Distance setting indicates how close to the
shore you want the Auto Guidance line to be placed. The
Auto Guidance line may move if you change this setting while
navigating. The available values for the Shoreline Distance
setting are relative, not absolute. To ensure the Auto
Guidance line is placed the appropriate distance from shore,
you can assess the placement of the Auto Guidance line
using one or more familiar destinations that require
navigation through a narrow waterway.
