Speedometer Setup; Speed Auto Calibrate - Ford F100 1953 Installation Manual

Speedometer Setup:

There are two ways to calibrate the speedometer. Speed auto calibrate
(using an exact marked mile) and real-time speed adjust (manually adjust speed
up or down). It is recommended you use the speed auto calibrate option first and
then make any fine tune adjustments using the real-time speed adjust option.

Speed Auto Calibrate:

1) Tap the pushbutton until the
tachometer points to 3000 RPM
(speed auto calibrate option). Fig.
2) Press and hold (4 seconds) the
pushbutton to enter the speed auto
calibrate mode. The speedometer
will point to 30 MPH indicating you
are in speed auto calibrate mode.
3) Begin driving the measured mile. The
tachometer will operate as normal but the odometer will not
move. When a speed signal is detected, the speedometer
will point to 45 MPH. If a speed signal is NOT detected, the
speedometer will continue to point at 30 MPH.
4) At the end of the measured mile, press and hold the
pushbutton. The speedometer will again point up and the
tachometer will point to 8000 RPM
(exit). The speedometer is now
calibrated.
5) If you are finished making setup
changes, press and hold the
pushbutton with the tachometer
pointing to 8000 RPM to exit
setup mode. Fig. 8
