Fuel logging
You must ensure all fuel fills are recorded using the fuel
manager.
From the fuel manager page:
1. When filling the tanks until full select All tanks full.
The estimated fuel remaining is reset to the value of your
fuel tanks capacity.
2. When only partially filling the tank make a note of the volume
of fuel added to the tank and then select Add partial fill.
3. Enter the value noted earlier this will be added to your current
fuel remaining figure.
Note: It is recommended that you perform an 'All tanks full' fill
up as regularly as possible as partial fills will cause a higher
cumulative inaccuracy in the provided calculations.
Setting the low fuel alarm
Using the fuel manager also allows you to set a low fuel alarm
which, if activated, is sounded when your vessel's remaining
fuel falls to a specified value.
With the fuel manager turned on and set up correctly:
1. From the homescreen select Set-Up.
2. Select Alarms.
3. Select Fuel manager.
The low fuel alarm settings are displayed.
4. Select Low Fuel so that On is highlighted.
Selecting Low Fuel will turn the low fuel alarm On or Off.
5. Select Fuel Level.
The fuel level numeric adjust control is displayed.
6. Adjust the fuel level to the required value.
The low fuel alarm will now be sounded when the fuel remaining
in the tank falls to the value specified.
Note: By default the low fuel alarm is switched off.
Resetting fuel used readings
You can reset the value of the fuel used this season or fuel used
this trip by following the steps below.
From the fuel manager page:
1. Select Reset against fuel used this season, or
2. Select Reset against fuel used this trip.
The value is set to zero after Reset has been selected.
Note: Performing a Season reset automatically resets the
trip value.
Fuel range rings
The fuel range ring gives an estimated range that can be
reached with the estimated fuel remaining on-board.
Fuel manager
The fuel range ring can be displayed graphically in the chart
application and indicates an estimated range that can be
reached with the:
• Current rate of fuel consumption.
• Estimated fuel remaining on-board.
• Course remaining in a straight line.
• Current speed maintained.
Note:
The fuel range ring is an estimated range that can be reached
at the current rate of fuel consumption, of the fuel onboard
and based on a number of external factors which could either
extend or shorten the projected range.
This estimate is based on data received from external fuel
management devices, or via the Fuel Manager. It does not
take into account prevailing conditions such as tide, current,
sea state, wind etc.
You should not rely on the fuel range ring feature for accurate
voyage planning or in emergency and safety critical situations.
Enabling the fuel range ring

1. Select Menu.
2. Select Presentation.
3. Select Overlays.
