System Alarms
Alarm Clock: Sets an alarm clock.
Unit 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.
Sonar Alarm Settings
NOTE: Some settings require external accessories.
Select Settings
> Alarms > Sonar
.
Shallow Water: Sets an alarm to sound when the depth is less
than the specified value.
Deep Water: Sets an alarm to sound when the depth is greater
than the specified value.
Water Temp.: Sets an alarm to sound when the transducer
reports a temperature that is 2°F (1.1°C) above or below the
specified temperature.
Contour: Sets an alarm to sound when the transducer detects a
suspended target within the specified depth from the surface
of the water and from the bottom.
Fish: Sets an alarm to sound when the device detects a
suspended target.
• sets the alarm to sound when fish of all sizes are
detected.
• sets the alarm to sound only when medium or large
fish are detected.
• sets the alarm to sound only when large fish are
detected.
Setting Weather Alarms
Before you can set weather alarms, you must have a compatible
chartplotter connected to a weather device, such as a GXM
device, and have a valid weather subscription.
1
Select Settings
> Alarms > Weather
.
2
Turn on alarms for specific weather events.
Setting the Fuel Alarm
Before you can set a fuel level alarm, a compatible fuel flow
sensor must be connected 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 >
Set Total Fuel Onboard
> On
.
2
Enter the remaining amount of fuel that triggers the alarm,
and select Done
.

hardware.

Depth and Anchoring: Allows you to enter information about
the keel (Setting the Keel Offset
, page
17) and the anchor.
Temp. Offset: Allows you to set an offset value to compensate
for the water temperature reading from a NMEA 0183 water-
temperature sensor or a temperature-capable transducer
(Setting the Water Temperature Offset, page 45).
Calibrate Water Speed: Calibrates the speed-sensing
transducer or sensor (Calibrating a Water Speed Device,
page 46).
Fuel Capacity: Sets the combined fuel capacity of all the fuel
tanks on your vessel (Setting the Fuel Capacity of the Vessel,
page 33).
Vessel Type: Enables some chartplotter features based on the
boat type.
CZone™: Sets the digital switching circuits.
System Profiles: Allows you to save your system profile to a
memory card and import system profile settings from a
memory card. This can be helpful for charter or fleet vessels,
and for sharing your setup information with a friend.
Setting the Keel Offset
You can enter a keel offset to compensate the surface reading
for the depth of a keel, making it possible to measure depth from
the bottom of the keel instead of from the transducer location.
Enter a positive number to offset for a keel. You can enter a
negative number to compensate for a large vessel that may
draw several feet of water.
1
Complete an action, based on the location of the transducer:
• If the transducer is installed at the water line
À
, measure
the distance from the transducer location to the keel of the
boat. Enter this value in steps 3 and 4 as a positive
number.
• If the transducer is installed at the bottom of the keel
Á
,
measure the distance from the transducer to the water
line. Enter this value in steps 3 and 4 as a negative
number.
2
Select Settings > My Vessel > Depth and Anchoring >
Keel Offset.
3
Select or based on the location of the transducer.
4
Enter the distance measured in step 1.
Setting the Water Temperature Offset
Before you can set the water temperature offset, you must have
a NMEA 0183 water-temperature sensor or a temperature-
capable transducer to measure water temperature.
The temperature offset compensates for the temperature
reading from a temperature sensor.
1
Measure the water temperature using the temperature sensor
or temperature-capable transducer that is connected to the
chartplotter.
2
Measure the water temperature using a different temperature
sensor or a thermometer that is known to be accurate.
3
Subtract the water temperature measured in step 1 from the
water temperature measured in step 2.
This is the temperature offset. Enter this value in step 5 as a
positive number if the sensor connected to the chartplotter
measures the water temperature as being colder than it
actually is. Enter this value in step 5 as a negative number if
the sensor connected to the chartplotter measures the water
temperature as being warmer than it actually is.
