My Versa is a year old. Recently it has not been tracking my heart beat and it had begun to turn off suddenly. After charging it last night it was working fine but around midday it turned off. I have tried charging it again, pressing the 3 buttons as others have suggested and also pressing the left button with the bottom right one, but to no avail. The screen is black and it is not syncing with my phone. Anyone have any answers?
