1. Roll the wheel until the valve stem at its lowest point close to the ground, then mark this first  
point on the ground. (Fig. a)  
POWER AUTO ON/OFF  
2. Get on the bike and have a helper push you until the valve stem returns to its lowest point.  
Mark the second point on the ground. (Sitting on the bike achieves a more accurate reading  
since the weight of the rider slightly changes the wheel circumference).  
3. Measure the distance between the marks in milimeters. Enter this value to set the wheel  
circumference.  
Option: Get a suitable circumference value from the table. (Fig. b)  
4. Adjust the wheel circumference as the data setting process.  
5. Unit will change to the normal operation after this circumference setting.
