I need directions for a TOPEAK comp 140 cycyling computer.

When you put in the new battery it will be in set mode. First select km/h or m/h depending on your preference. Switch between the two by pressing the large button. Hold down the button 2-3 seconds to switch to the numbers at the bottom (the first number will start flashing). Set the circumference of your tire in mm. Push the button to change the numbers and hold down the button for 2-3 seconds to switch between numbers. (You can measure the circumference of your tire by lining up one spoke with the end of a tape measure and rolling down the tape one revolution, if you measure in inches Google can help you with the conversion to mm). Once you have set the circumference, press the set button on the back of the computer. Now you need to set the clock. Press the large button to select different modes. When the clock appears press the set button on the back to toggle to set mode. Use the large button to change the time just the same as setting the circumference. Press the set button when finished.
