After installing the battery, the default wheel factor '2124' will appear with the digit furthest to the right
blinking. This is the correct setting for a 26.6" (700 x 25C) tire. If this is your wheel size, press the upper
button four times to confirm each one of the four digits. If this is not your wheel size, use the Wheel
Diameter Size Chart on the next page to find the correct wheel factor (c). In the event your tire size is
not included in this chart, multiply your wheel diameter (d) in millimeters by 3.1416 to determine the
correct wheel factor (c).
To enter the correct wheel factor into the computer, press
the lower button until the correct digit appears. Press the
upper button to lock in the correct digit. Repeat until all
four correct digits are entered. To return to the Wheel Size
Input screen at any time, push the MaJOR FUNCTION reset
button on the back of the computer (see RESET FUNCTIONS
- baCk section).
