Hi
Explanation
When you plug the power supply, Direto places itself to what we call "default starting point".
This position has a little resistance (it's not a 0 resitance position). It is needed in case a user wants to use the trainer without any device, so he can still pedal on it without spinning around.
When you connect a device, instead, it places itself to the zero position (with no resistance).
So, to have minimum resistance when indexing the gear, this is what you have to do:
1. power on the trainer - it will go to the default starting point
2. connect it to a device (smartphone, tablet, pc...) - resistance will be put to zero
3. disconnect the power supply or keep it connected to the app while doing the indexing
