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.
Transducers: Shows all transducers on the network, allows you
to change transducers, and allows you to view diagnostic
information
(Selecting the Transducer Type, page
Depth and Anchoring: Allows you to enter information about
the keel
(Setting the Keel Offset, page
The Anchor Height value is the height of the anchor above
the waterline. The Anchor Scope value is the ratio of the
length of anchor rode in use to the vertical distance from the
bow of the vessel to the bottom of the water. These anchor
settings are used to calculate the Target Anchor Rode date
field.
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
Calibrate Water Speed: Calibrates the speed-sensing
transducer or sensor
(Calibrating a Water-Speed Device,
page
63).
Fuel Capacity: Sets the combined fuel capacity of all the fuel
tanks on your vessel
(Setting the Fuel Capacity of the Vessel,
page
47).
Vessel Type: Enables some chartplotter features based on the
boat type.
CZone™: Sets the digital switching circuits.
SeaStar Instance: 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.
Hull ID Number: Allows you to enter the Hull Identification
Number (HIN).The HIN might be permanently affixed to the
upper starboard side of the transom or outboard side.
Optimus Steering: Allows you to adjust the Optimus steering
parameters.
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.

Setting the Water Temperature Offset
The temperature offset compensates for the temperature
reading from a temperature sensor or temperature-capable
transducer.

Measure the distance:
• If the transducer is installed at the water line
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
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.
Complete an action:
• If the transducer is connected to the chartplotter or a
sonar module, select Settings > My Vessel > Depth and
Anchoring > Keel Offset.
• If the transducer is connected to the NMEA 2000 network,
select Settings > Communications > NMEA 2000 Setup
> Device List, select the transducer, and select Review >
Keel Offset.
Select
if the transducer is installed at the water line, or
select
if the transducer is installed at the bottom of the
keel.
Enter the distance measured in step 1.
Measure the water temperature using the temperature sensor
or temperature-capable transducer that is connected to the
network.
Measure the water temperature using a different temperature
sensor or a thermometer that is known to be accurate.
Subtract the water temperature measured in step 1 from the
water temperature measured in step 2.
This value is the temperature offset. Enter this value in step 5
as a positive number if the sensor measures the water
temperature as being colder than it actually is. Enter this
value in step 5 as a negative number if the sensor measures
the water temperature as being warmer than it actually is.
Complete an action:
• If the sensor or transducer is connected to the chartplotter
or a sonar module, select Settings > My Vessel > Temp.
