Set remaining

Before doing a partial refill of the tank or remov- ing fuel manually from the tank (for example, by siphoning it off):

1.Note the Remaining reading on the Fuel display.

2.Note how much fuel is added or removed.

3.Calculate how much fuel is now in the tank.

4.Select Set remaining and update the reading.

It is essential to do this whenever some fuel is added or removed. Otherwise, the read- ing on the Fuel display (see section 5-6 Fuel Display) and the Low Fuel Alarm (see section 3-5 Setup > Alarms) are meaningless.

Clear used

Select Clear used to set Used (the amount of fuel used) to zero. Do this to start measuring the amount of fuel used over a certain time or distance. When asked Are you sure? select Yes.

Tank size

Enter the capacity of the fuel tank.

Num engines

Set the number of engines to 0, 1 or 2. If 0 is selected the fuel features are turned off.

Calibrate

See section 3-8 Setup > Calibrate, for information about calibrating the fuel transducer(s).

Flow filter

Most engines do not draw fuel from the tank at a steady rate. To give a stable fuel flow reading, the fishfinder calculates the flow value(s) by taking several measurements and averaging them. Use the Flow filter to set the period over which the fuel flow is averaged.

For twin engine installations, the fuel flow for each engine must be adjusted separately.

TheFlowfiltercanbesetfrom0to30seconds. Use thelowestvaluewhichgivesastableflow.Usuallya valueof5to10secondswillgiveasatisfactoryresult for two-stroke carburettor engines. Fuel injected or four-stroke engines may require a larger value.

This setting affects the Fuel flow and Fuel economy reading on the Fuel display (see section 5-6 Fuel display) but it does not affect the Fuel used reading.

Speed Source

Select speed input from water speed transducer or externalGPSsource(anexternalGPSsourcemust beconnectedtotheFishfinderviaNavBusorNMEA comms – see section 3-7 Setup > Comms.)

3-4 Setup > Logs

Press MENU one or more times until the Setup menu is displayed, then select Logs:

The values can be changed independently of each other. These log values are saved when the unit is turned off.

Reset trip dist

This resets the trip distance to zero.

Reset total dist

This option resets the total distance to zero.

Reset engine hours

Use this option to reset the engine hours to zero. This can be useful after an engine service or to count the engine hours between service intervals.
