•   NMEA Input/Output—controls the input and output of 

NMEA 0183 version 3.01 data to and from the Fishfinder. 

This setting must be On to receive GPS navigational data 

and send Sonar NMEA data. See page 17 for details on 

available NMEA sentences.

•   Factory Settings—restores all settings to the original factory 

default values. The Fishfinder 340C turns off and back on 

again when you select Yes.

•   Software Version—displays the Fishfinder’s software 

version, copyright date, and unit ID.

•  Reset Odometer—this option appears only if you are using 

a speed-capable transducer/sensor. This resets the odometer 

field to zero.

The Units tab enables you to define the units of measure. 

The following settings are available:

•  Depth—lets you select the units of measure for depth in 

Feet (ft), Fathoms (fa), or Meters (m).

•  Temperature—lets you select the units of measure for 

temperature in Fahrenheit (°F) or Celsius (°C).

•  Distance and Speed—lets you select the units of measure 

for distance and speed readouts in Nautical (nm/ft, kt), 

Nautical (nm/m, kt), Statute (mi, mh), or Metric (km, kh).

•  Position Format—changes the coordinate system in which 

a position reading appears. The default format is latitude and 

longitude in degrees, minutes, and thousandths of a minute
