M5
Bike selection: bike 1 or bike 2
The VDO M5 has an automatic bike recognition function.
The digital data from the speed transmitter also informs the
VDO M5 of whether bike 1 or bike 2 is currently being used.
The total data is correspondingly stored for bike 1 or bike 2.
ATTENTION: when using the transmitter for the first time, the
bike recognition switch must be set to either BIKE 1 or BIKE 2.
Only then will the automatic bike recognition work.
See Setting the transmitter on page 16.
