Conguring the Chartplotter
Setting the Total Fuel Onboard Alarm
You can congure your chartplotter to sound an alarm when the total
amount of remaining onboard fuel reaches the specied level.
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 Congure > Alarms > Fuel >
Total Onboard > On (or Off).
2. If you select On, use the Rocker to indicate the fuel level at
which the alarm should sound.
Conguring My Boat
To congure settings for your boat, from the Home screen, select
Congure > My Boat.
Keel Offset
—offset 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. Enter a negative number to compensate for a large
vessel that may draw several feet of water.
To adjust the Keel Offset:
1. From the Home screen, select Congure > My Boat > Keel
Offset.
2. Use the
Rocker to enter the measured distance from the
transducer location to the water line or to the keel of the boat.
If you are measuring down to the keel (transducer installed at
the water line), enter a (+) positive number. This shows the
depth at the bottom of the keel.
If you are measuring up to the water line (transducer installed
on the bottom of the keel), enter a (-) negative number. This
shows the depth at the surface.
3. Select Done to accept the number.
A (+) positive number
shows depth at the bottom
of the keel.
