Device with key panel
The device has the following keypads:
•
2 x 8 vertical keypads with softkey functions
•
2 x 10 horizontal keypads with function keys F1 -F20
The number of keys, their labeling and function is the same on all key panels. The various
panel types differ only in the arrangement of the keys and in the size and type of the display.
The following figure is therefore only an example using the front view of the 12" variant.
