2.2 Operating Units with Keypad Fronts
The front side of the Panel PC 670/870 is equipped with a membrane keyboard
and mouse.
The integrated USB mouse with two mouse buttons is a "piezo mouse", i.e. the
direction of the mouse pointer movement is controlled by the position of
pressure on the pressure surface, while the speed of the mouse pointer
movement is controlled by the force of pressure applied.
Optionally an external mouse can be connected to the USB port at the front.
The piezo mouse remains active in this case.
The arrangement of the operating elements is illustrated in Figure 2–4.

can be edited and printed using MS Word, MS Excel or Coral Draw.
Only the keyboard labeling strips, available on option, are suitable for printing
using a laser printer.
