How to Set up a Sigma Sport Wireless BC 1200 Bike Computer

Bicycle computers take the cycling experience to the next level. The Sigma Sport Wireless BC1200 computer performs several functions, such as current distance travelled, ride time, average speed, maximum speed, current speed and overall distance travelled. The BC1200 works on two different bikes with a setting for "bike 1" and "bike 2" that keeps track of the statistics for each bike separately. Before you start using your computer, though, you need to set up basic functions, including time of day, and more important things, such as the tire size of your bike or bikes.

Set the time on your Sigma Sport Wireless BC1200 computer by pressing the bottom button until the computer displays the clock at the bottom of the screen. Turn the computer over and press and hold the grey "set" button until the clock flashes.

Press the top button until you reach the correct hour. Press the bottom button to switch to minutes. Press the top button until you get to the correct number of minutes. Press the bottom button to set the seconds. Use the top button to get to the correct number. Turn the computer over and press the grey "set" button for one second to set the time.

Press the grey "set" button, ensuring that the Sigma Sport Wireless BC1200 Computer is set to "bike 1." Press the bottom button until "set language" flashes. Press the top button to choose between available languages. Press the bottom button to accept your selection.

Press the bottom button to enter the MPH/KMH screen and select either miles or kilometres as your preferred method of measuring speed and distance. Press the top button to confirm your selection.

Press the top button to advance numbers. Press the bottom button to make the next digit flash. Repeat this process until you input all four numbers of your wheel size into the computer. Press the grey "set" button on the back of the computer to store your selection.
