To calibrate the water speed:
1. On the
Sonar tab, use the ROCKER to highlight Calibrate
Water Speed, and press ENTER.
2. Bring the boat to a cruising speed. The top ground and
uncalibrated water speeds are shown at the bottom of the
calibration window. Note your top water speed, stop the
boat, and press
ENTER.
3. By default, the top ground speed automatically displays
in the What was your top water speed? field. If a ground
speed is not available, the top uncalibrated water speed is
used instead. If the new speed is correct, highlight
OK, and
press
ENTER. If you want to manually enter a calibration,
press
ENTER on the speed field, enter a new speed, and
then press
ENTER.
4. You can also press
MENU on the calibration screen and
choose
Use Top Ground Speed to default back to ground
speed or
Use No Calibration to use the speed sensor’s
uncalibrated speed.
NOTE: If the boat is not moving fast enough or the speed
sensor is not outputting a speed, the message “Boat Is Not
Moving Fast Enough To Calibrate” appears at the bottom of
the screen. Either verify the speed sensor wheel is moving, or
safely increase boat speed. If there is a problem with the speed
sensor/unit, or if a speed senor is not installed, a “Water Speed
Sensor Is Not Working” message appears at the bottom of the
screen. Check connections of speed sensor cables.
