There are 2 ways of setting the stride length on Geonaute pedometers: automatically (AUTO) or manually (MANU). This setting is applied in the 'Set' menu of your pedometer.
AUTO: Depending on your height, the pedometer will automatically calculate your stride length using a patented Oxylane algorithm.
MANU: For the most accurate results, you can enter your stride length manually.
To measure your stride length: Walk 10 metres, counting the number of steps you take, then use the following formula: 10 metres/number of steps = length of stride
