Why is the screen upside down?

Print

If the Wall Charger option has been ticked in the Screen Settings menu, the screen will be inverted and the navigation buttons reversed while the pager is on the wall charger. Note that the Wall Charger option is only available when the Screen Orientation Feature is enabled. The pager can still be operated in a normal way, just upside down. The screen will revert to the normal orientation when the pager is removed from the charger.
