As stated in the manual, I have set the stride length and the pedometer (which is an odometer) positioned as indicated on the waistband. Unfortunately, the result was much too low. I went different routes, which were provided with a km-specified and controlled this also with electronic pedometers from two different vendors. Other positionings of the Walk 20 also always resulted in a too low result. So I created the Walk 20 sent back.
