Speedometer Function
The speedometer measures speed over the water using a paddle
wheel sensor.
Speedometer Calibration
The analog speedometer displays the speed of the boat through the
water. The speedometer is calibrated at the factory; however,
significant variations can occur due to changes in installations. The
speedometer can be easily calibrated to a known reference such as
a radar gun, measured course or GPS.
When the unit is in digital speed display mode, push and release M
to put the speedometer in the calibration mode. Push and hold M
down for at least two seconds; the LCD will show “AdJUST.”
Run the boat at a constant 30 MPH as measured by the GPS, radar,
or closed course. Adjust the speedometer pointer by pressing
s
and
t
until the speedometer matches the known speed.
When finished, press M to exit the adjustment screen. The operator
has the option of saving or canceling the adjustment procedure.
The options can be selected using
s
and
t
. To save the calibration
setting, press and hold
M
for two seconds when the display shows
“SAVE.”
