If you are turning on your Fishfinder 340C for the first time, use the
following procedure. If you have already turned on your Fishfinder,
and you are just familiarizing yourself with the basic functions,

installed and not blown. If the Fishfinder is connected to a
power supply that exceeds safe operating levels, a “Battery
voltage is too high” warning appears and the Fishfinder
turns off. If the Fishfinder does not detect a transducer, it
automatically enters Simulator mode (see page 42 ).
2. When the Fishfinder detects a transducer at initial start up,
a Select Transducer Type window appears. Press ENTER .
3. Use the ROCKER to select your transducer type, and press
