Don't turn on the display. At the bottom of the display screen, you see a pushpin with a minus, a circle and a pushpin with a plus. Hold the circle for 12 seconds. The display will turn on, but ignore it until the reset to factory message shows.
Good luck!

Hello,

I have the same problem, but the solution doesn`t work for me :-( I set the background light to go out after 15 seconds.
So when the screen is dark I press the circle button, the display lights up after 1 second, I hold the circle button still down for 12 more seconds, but then only the dial pad appears. Any other suggestion?
Many thanks
