Average Speed mode
Average Speed mode is indicated by " AVS". The average speed since the last reset
is displayed. It is updated every ten-second count of the timer. The average speed is
reset to 0.0 km/h or mile/h once the tripmeter or timer is reset or overflows.
(Note: The average speed has a range of 0.0 to 99.9 km/h or mile/h and a reset
value of 0.0)
When the cycling speed is slow (about 10 km/h or below), the LCD sometimes
displays "00", because the sensor is less sensitive at very low speed. The display
reverts to the correct speed again. *See Important Note at back of manual *

reset is displayed. The maximum speed is reset once the timer or the tripmeter is
