3.3 Optical trackball
As a mouse alternative the keyboard is equipped with an optical trackball inclusive two mouse function keys
allowing comfortable and ergonomic handling of the PC, for instance from a sofa. Thereby the handling of
the Track Ball is as simple as brilliant.
• Move with the right thumb softly the ball of the trackball
to move the cursor on the screen.
• With the mouse function keys click and double click functions, absolutely
identically as with a mouse, can be explained.
• In order to "drag", to draw or to mark, you must keep the left key with the
left thumb pressed to carry out the function then with the right thumb on
the trackball.
• In order to increase or decrease the speed of the Mouse-pointer
movements, change the settings of the mouse options in your system
control under Windows.
• Using notebooks with already integrated touchpad you have to de-
activate these intern control devices in case of error messages or
malfunctions.
• The trackball resolution can be adjusted in the sequences of 400, 600 or
800 dpi after each time of pressing left + right mouse buttons at the same
time longer than 5 seconds.
Should the precision of the cursor decrease after several months of usage, the following things could be
responsible for that:
• Please check the installed batteries for their state. In the case of doubt exchange them for new.
Advise: A too low battery capacity might be responsible for the fact that the operation distance to the
radio remote control of the PC is impaired respectively signs are let out sporadically when writing.
• For cleaning DO NOT use sharp or pointed objects respectively liquid detergents, solvents or gasoline!
