For example, if you figure the sensor is reading 10 percent faster than
actual speed, you will enter – 10 in the calibration window. If the sen-
sor is reading 5 percent slower than true speed, you will enter + 5 in
the window.

sible. (Unless, of course, you are taking the current speed into consid-
eration when making your calculation.) After you have a correction fig-
ure, here's how to enter it:
