Calibration Using the Speedometer
In order to calibrate using the speedometer, you must drive
steadily at 40 km/h (25 MPH) and press a button on the Trip
500AL. The Trip 500AL bases its calibration on the speed of
the vehicle at the moment of calibration which it assumes to
be 40 km/h (25 MPH). Because of the nature of this calibration
procedure, we strongly recommend that it be performed by
two people: one to drive the vehicle and one to operate the
Trip 500AL.
NOTE: If you have entered a security code, you will need to enter that
code before the Trip 500AL will allow access to the calibration
screen.
1. Press and hold MODE to access the settings screens.
