1. Setting Km/H or Mile/H
A) Press the button on bottom of computer for 6 seconds to start setup.
B) Hold the button until the flickering digit is changed to the digit “2” of the C2155 to recognize either Km/H or Mile/H as desired.

2. Setting the wheel circumference C mm
A) The default is set at 2155mm. Measure the value for your wheel.
B) A quick press of the button advances the flickering digit by 1.
C) To change the flickering digit, hold down the button until the flickering digit moves to the next digit.
D) Hold down the button until (about 6 seconds) it jumps out the setting to store the desired data and complete setup.

3. Wheel circumference
A) Precise measurement: Roll wheel 1 revolution, measure the distance from the marked first point and the second point.
B) Measure the Wheel Radius R
Cmm = 6.2832 x R (R in mm)
Cmm = 159.60 x R (R in inches)
(1 inch = 25.4mm)
