From an applicable sonar view, select MENU > Sonar Setup >
Alarms .
You can also open the sonar alarms by selecting 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.
FrontVü Alarm : Sets an alarm to sound when the depth in front
of the vessel is less than the specified value, which can help
you avoid running aground ( Setting the FrontVü Depth Alarm ,
page 28 ). This alarm is available only with Panoptix FrontVü
transducers.
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 .
My Vessel Settings
NOTE: Some settings and options require additional charts or
hardware.
Select
Settings > My Vessel .
Depth and Anchoring : Allows you to enter information about
the keel ( Setting the Keel Offset , page 20 ) 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 52 ).
Calibrate Water Speed : Calibrates the speed-sensing
transducer or sensor ( Calibrating a Water Speed Device ,
page 53 ).
Fuel Capacity : Sets the combined fuel capacity of all the fuel
tanks on your vessel ( Setting the Fuel Capacity of the Vessel ,
page 40 ).
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 water depth
reading for the transducer installation location. This allows you
to view the depth of the water below the keel or the true depth of
the water, depending on your needs.
If you want to know the water depth below the keel or the lowest
point of your boat and the transducer is installed at the water
line or anywhere above the end of the keel, measure the
distance from the transducer location to the keel of the boat.
If you want to know the true water depth and the transducer is
installed below the water line, measure the distance from the
bottom of the transducer up to the water line.
NOTE: This option is only available when you have valid depth
data.
1
Measure the distance:
• If the transducer is installed at the water line
À
or
anywhere above the end of the keel, measure the
distance from the transducer location to the keel of the
boat. Enter this value as a positive number.
• If the transducer is installed at the bottom of the keel
Á
and you want to know the true depth of the water,
measure the distance from the transducer to the water
line. Enter this value in as a negative number.
2 Select Settings > My Vessel > Depth and Anchoring >
Keel Offset .
3
Select if the transducer is installed at the water line, or
select if the transducer is installed at the bottom of the
keel.
4 Use the arrow keys to enter the keel offset 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.
