Setting Weather Alarms
NOTE: You must have a subscription to XM WX Weather and a Garmin XM WX Weather receiver
(such as a GDL 30A) connected using the Garmin Marine Network to view weather information. See
page 58 for more information.
1. From the Home screen, select Congure > Alarms > Weather.
2. Turn the following alarms on or off: marine, tornado, severe storm, ood, or ash ood.
Setting the Total Fuel Onboard Alarm
NOTE: To receive fuel-level information, your chartplotter must be connected to an external fuel
sensor, such as the Garmin GFS 10.
You can congure your chartplotter to sound an alarm when the total amount of remaining onboard
fuel reaches the level you specify.
To enable the Total Fuel Onboard alarm and set the fuel alarm level:
1. From the Home screen, select Congure > Alarms > Fuel > Total Fuel Onboard > On.
2. Use the Rocker to indicate the fuel level at which the alarm should sound.
To disable the Total Fuel Onboard alarm:
From the Home screen, select Congure > Alarms > Fuel > Total Fuel Onboard > Off.
Conguring My Boat
From the Home screen, select Congure > My Boat.
Keel Offset—offsets 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.
Temp Offset—set the temperature offset for the temperature sensor of your transducer.
Calibrate Water Speed—calibrates a speed-sensing device. Follow the onscreen directions for
calibration. If you do not have a speed-sensing transducer, this menu does not appear.
NOTE: If the boat is not moving fast enough or the speed sensor is not registering a speed, a “Speed
Too Low” message appears. Select OK and safely increase boat speed. If you get the message again,
stop the boat and make sure the speed-sensor wheel is not stuck. If the wheel turns freely, check the
cable connections. If you continue to get the message, contact Garmin Product Support.
Fuel Capacity—enter the total fuel capacity of all your engines.
