Not operate the setup menu

Is this the Bosch controller? If so maybe pull off the bike or make sure it is seated properly. Water can be an issue as well. -S

EDIT: I gather from your other post that this is a Stromer issue, good luck. -S
when I press the power button and +at the same time for 3 sg, does not enter the setup menu, someone happened that?
Just to confirm: Is the bike already on and past the bootup screen before you hold the power button and the + for 3 seconds?
