GPX Pro 22

Similarly, during a roll-on, the display of the GPX will invert when you hit the minimum speed (e.
g., 60 if the setting is for a 60-100 roll-on), and will revert back to normal when you hit the top
speed.
When the drag is completed, its summary screen is shown:
To review your drag races, from the main screen press the Left and Right arrows to cycle through
the races. Press Menu to return to the main screen.
When you start a drag session, if you change your mind, press any button to terminate it.
When you do a roll-on, if the roll-on maximum speed is less than the roll-on minimum speed + 10,
the maximum speed is set to the minimum speed + 10. For example, if you set the roll-on
minimum speed to 50, and the roll-on maximum speed to 55, the maximum will actually be set to
60. (There must be at least a 10 mph difference from the minimum to the maximum.)

Accelerometer sensitivity
Depending on the mounting of the GPX and the amount of vehicle vibration, you may need to
adjust the acceleration sensitivity for drag races. The menu item Acceleration sensitivity allows
you to change it. High sensitivity means the GPX will be most sensitive to the slightest
movement; Low means the GPX will be more lenient to vibration.
