You can set the display to Scan Mode where each function is displayed for 3 seconds before displaying the next. Automatically turns on when you pedal and turns off when not in use. Has an additional function that the standard display doesn’t have. In addition to the distance measurement that can be erased by resetting the display, there is an odometer function that does not get erased when you reset the display. This keeps track of the total miles when using the bike.
