3.3 Earthing of the system
For EMC reasons an earthing via the earthing screw must be carried out in eit-
her case.
3.4 Operational elements on the front side
The system has an illuminated graphical display with a resolution of 160 x 32
pixel and 19 operating buttons.
On the right next to the display there are two softkeys whose current
functions are indicated on the display. In the middle there are two cursor but-
tons (upwards/downwards), two buttons for accepting/dropping calls as
well as an
OK
button. The numerical pad supports in addition to the numerical
characters
0...9
, the ’
*
’- and ’
#
’-key. For text entries the numerical pad can also
be used as a normal keypad.
During a connection additional functions are possible that are explained in
chapter 5 - “Operation via display and keypad“.
The operation is similar to standard mobile telephones.

Depending on the delivery status all menus are possibly displayed in German. The configuration
of the menu language is described in CHAPTER 5.1.2.
ATTENTION Earthing
A lacking earthing can cause functional deficiencies within the unit. Because
of the “pending“ potential, unlike the protective earth conductor potential,
slight electric shocks can occur by touching the rack. These are absolutely not
dangerous, however they can be avoided totally by earthing.
