When i first got mine it prompted me to enter the circumference of my tire in millimeters (mine was 2074mm). you can get back to this by holding the bottom button in the center (this button is really two buttons one on the left side the other on the right side; holding the center pushes both these buttons). when it rests you'll see the 4 digit numbers. i think u use the right button to change the number and the left to move to the next. remember the number represents your tires circumference in millimeters. for a quick approx use this calculation (Tire Diameter)X(3.14)X(25.4). So for me it was (26in)X(3.14)X(25.4) = 2074mm
