Catrin...I see that you found how to reset it, but I'm curious to know if it's the same way that my Sigma was. I had the BC2209 model, and to reset this one I had to hold the 2 buttons on the left side (top & bottom) together for about 3 seconds. I now have a Garmin Edge 500 which I do love, but my Sigma served me well during the time that I used it. The only problems I ever had with it, was sometimes it would not pick up the cadence signal. But this was generally due to the cadence sensor accidentally getting bumped and so the magnet wasn't lined up correctly with the sensor. I quick adjustment usually did the trick. I think it's a great computer for a good value.
