Setting the Fuel Alarm

The Beeper setting must be turned on to make alarms audible
to set audible alarms could lead to injury or property damage.
Before you can set a fuel level alarm, you must connect a compatible fuel flow sensor 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.

Synchronizing the Fuel Data with the Actual Vessel Fuel

If you are using fuel flow sensors, you must synchronize the fuel levels in the chartplotter with the actual
fuel in the vessel when you add fuel to your vessel. If you are using fuel tank sensors, the level is adjusted
automatically based on the tank level sensor data and it is not necessary to synchronize fuel levels manually
(Fuel Settings, page 174).
