3.3 Earthing of the system
For EMC reasons an earthing via the earthing screw of the system must be car-
ried out in either case.
3.4 Operational elements on the front side
The system has an illuminated graphical display with a resolution of 160 x 32
Pixels and 21 operating buttons.
On the right next to the display there are two softkeys whose current func-
tions are indicated on the display. In the middle there are two cursor buttons
(upwards/downwards), two buttons for accepting/dropping calls as well as
an
OK
button. The numerical pad supports in addition to the numerical char-
acters
0...9
, the ’
*
’ and ’
#
’ key. For text entries the numerical pad can also be
used as normal keypad.
The operation is similar to standard mobile telephones.
