Navigation is done using different buttons. With the end button you can cancel actions or go back
one step. When you press and hold the home button you will go directly back to the main menu.
Actions are confirmed or executed with the call button. Use the vertical buttons to navigate within
the menus.
If you operate the system with the touch screen then it gets dirty over time. As a result the readabil-
ity of the information on the display and the input functionality is impaired. Please clean the display
as required with a damp, lint-free cloth. Please do not use any liquid cleaners.
