3. Drive the vehicle until you reach 25 MPH (40 km/h) and keep the vehi-

cle steady at that speed.

4. Once the vehicle is moving at the calibration speed, press and hold

SET/CLEAR

down.

The word CAL appears in the top right of the display when you press

SET/

CLEAR

5. Continue to hold

SET/CLEAR

down until the unit beeps and the word

dONE appears on the display.

This indicates that the unit has finished calibrating. The speed reading at the
top of the display will also change so that it reads much closer to your speedom-
eter’s reading.

6. Once the calibration is complete, drive the vehicle and compare the

vehicle’s speedometer to the DriveRight 130AL’s speed display.

Be aware that the DriveRight 130AL responds to changes in speed faster than
most vehicles’ speedometers. To accurately compare, you must drive steadily at a
speed for a short time.

7. If necessary, “fine tune” the calibration by pressing

"+"

"-"

Each time you press "+" or "-", the DriveRight 130AL speed reading adjusts up
or down. Depending on the speed of the vehicle and the calibration, you may or
may not see a change in the speed reading in the calibration screen each time
you press the button.

NOTE:

Pressing and holding "+" or "-" down increases the rate at which the

DriveRight 130AL adjusts the speed reading.
