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,
please go to "Learning the Basic Functions" on this page.
To start your Fishfinder for the first time:
1. Press and hold the Power/Backlight key until the
Fishfinder beeps. It should turn on. If the Fishfinder fails to
turn on, verify that the wiring adapter is properly connected
in the back of the Fishfinder, the Red and Black wires are
connected to the correct polarity, and that the 3-Amp fuse is
installed and not blown. If the Fishfinder is connected to a
power supply that exceeds 35 volts DC, 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 22).
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
ENTER.
4. Press QUIT to return to the Sonar Page.
