Initializing Fishnder 300C
Settings
The rst time you turn your Fishnder
300C on, you must congure a series of
initial settings. These settings must also be
congured when restoring factory settings
(page 14). Each of these settings can be
changed later using either the Sonar Setup
screen (Color Scheme) or the Congure
screen (Language and Units).

1. Language—select the on-screen
language.
2. Units—select Statute (mh, ft, °F),
Metric (kh, m, °C), or Nautical (kt, ft,
°F).
3. Color Scheme—select White or Blue
as the background on sonar screens.
4. Select OK.
