a connected Garmin XM WX weather receiver to view weather
information (page 68).

2. Turn the following alarms on or off: marine, tornado, severe
storm, ood, or ash ood.
Setting the Total Fuel Onboard Alarm
You can congure your chartplotter to sound an alarm when the total
amount of remaining onboard fuel reaches the specied level.
NOTE: To receive fuel-level information, your unit must be
connected to an external fuel sensor, such as the Garmin GFS 10.
To enable the Total Fuel Onboard alarm and set the fuel
alarm level:
1. From the Home screen, select Congure > Alarms > Fuel >
Total Onboard > On (or Off).

Congure > My Boat.
Keel Offset—compensates for 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.
To adjust the Keel Offset:
1. If the transducer is installed at the water line, measure the
distance from the transducer location to the keel of the boat.
Enter this value in step 3 as a positive number.
If the transducer is installed at the bottom of the keel, measure
the distance from the transducer to the water line. Enter this
value in step 3 as a negative number.
