Putting the system into operation
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 Operating 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 buttons for nav-
igation (selection upwards/downwards), two buttons for accepting/drop-
ping calls as well as an
OK button. The numerical pad supports in addition to
the numericals
0...9 also the ’ * ’and ’ # ’button. For entering text the numerical
pad can also be used as a normal keypad.
The operation is similar to standard mobile phones.
