Initializing Fishfinder 300C Settings
The first time you turn your Fishfinder 300C on, you must configure a series of initial settings. These settings must also be configured when restoring factory settings (page 14). Each of these settings can be changed later using either the Sonar Setup screen (Color Scheme) or the Configure screen (Language and Units).
To initialize your Fishfinder 300C settings:
1.Language—select the on-screen language.
2.Units—selectStatute (mh, ft, °F), Metric (kh, m, °C), or Nautical (kt, ft, °F).
3.Color Scheme—selectWhite or Blue as the background on sonar screens.
4.Select OK.
Alarms and Messages
The Fishfinder 300C uses an on-screen message system to alert you to operating characteristics. When a message appears, press SELECT to acknowledge the message and return to the screen you were viewing.
Battery Alarm—battery voltage has fallen below the value entered in the battery-alarm screen (Configure > Alarms > Battery > On).
Battery Voltage Is Too High—The input voltage is too high. The Fishfinder 300C will shut off in 10 seconds. Decrease the input voltage to 33 volts or less.
Boat Is Not Moving Fast Enough to Calibrate—the boat is not moving fast enough for the speed wheel to provide a valid speed.
Can’t Read Voltages That High, Limited to Top of Range—thebattery-alarm screen voltage value is higher than the Fishfinder 300C can read.
