Advanced Options menu 
The Fuel Flow sensor Advanced Options menu contains two categories: 
Instance and Restore Defaults. 
Instance 
The Instance command is intended for use only by experienced NMEA 
2000 network technicians. Instance allows network technicians to re-
solve certain electronic probe conflicts. This is most likely to occur if the 
network includes LMF-200 or LMF-400 digital gauges, which support 
the display of fewer electronic probes than your GPS or sonar/GPS unit. 
If you want to use your unit in a network including one of these digital 
gauges, you may need to consult customer service. 
You should never need this command if you are connecting your unit to 
a network with similar display units and/or a series of electronic 
probes. 
Restore Defaults 
The Restore Defaults command allows you to reset an individual EP-15 
Fluid Level Sensor's settings to factory defaults. If, for example, you 
execute the Restore Defaults command from your Gray Water Fluid 
Level Advanced Options menu, only the settings for the Gray Water 
Fluid Level will be reset to factory defaults. Other fluid levels on the 
network will not be affected. 
To restore default settings: 
1. Press MENU| MENU, use ↑ ↓ to select NMEA 2000 and press ENT. The 
NMEA 2000 menu will appear with five options: Bus Setup, Fuel Man-
agement, NMEA 2000 Alarms, Waypoint Sharing and Backlight Syn-
chronization. 
2. Highlight 
BUS SETUP and press ENT, which will open the Bus Configu-
ration menu. A list of network devices will be at the top of the page. 
3. Select the desired fluid level and press 
ENT. The Device Configura-
tion menu will appear. 
4. Highlight 
ADVANCED OPTIONS and press ENT. 
5. Select 
RESTORE DEFAULTS and press ENT. The following message will 
appear: Are you sure you wish to change this device's configuration? 
6. Highlight 
YES and press ENT. Press EXIT repeatedly to get back to the 
main display. 
NOTE: 
The Fluid Level Device Configuration menu also contains the Cali-
brate button, but we will address that later in the segment covering 
Calibration.
