Question about Ruptor R6 v3 miedziany

I have not yet managed to change it via the ruptor app.
There is also additional information there
Attention abrasions from 25 km/h become big and ugly
Have fun

The app does not work from Ruptor can do it yourself in the display by hand..long press horn and power button together, then press with horn 2 times until P31 is on the screen then wait 2 - 3 seconds and with short 2 times horn press it is saved runs 55kmh on speedometer but goes by feeling faster ap 😉
