your system. You can also use the USB

3 Using the integrated
numeric keypad
3.1 Special key Fn
Due to the keyboard's space-saving design, the
numeric keypad has been placed in the area of the
main keys. For example, the functions "4", "5", "6"
and "+" are assigned to the keys U, I, O and P
(identified by a frame).
If Num Lock is switched on (Num LED on), the
integrated numeric pad of the keyboard is
consciously not yet active. The numeric pad will be
active not until the Fn button is pressed and hold
down.
Example: Fn + O = "6"
Pressing the Fn and O in that order and holding
them down together causes screen output "6".
Fn in combination with other keys switches
functions, each marked with a frame.
Example: Fn + F12 = "Num Lock on/off"
Pressing the Fn and F12 in that order and holding
them down together changes the Num Lock status.
3.2 Function level Pad
For longer numeric entries, repeat the steps above
to activate Num Lock (Num LED on) and use the
key combination Fn + F11 to turn on the function
level Pad (Pad LED on).
With function Pad on, the integrated numeric
keypad is permanently active.
The O key is permanently assigned the function "6",
for example.

4 Care and maintenance

The keyboard is maintenance-free. For occasional
external cleaning, a cloth moistened with water is
sufficient. Clean the ball in the trackball at regular
intervals with water and mild soap. Remove the ball
by gently pressing the trackball cover and at the
same time turning counterclockwise. Using
aggressive liquids such as alcohol or acids may
damage the ball and have a negative effect on its
functionality. Be careful when cleaning the optical
sensor (the transparent lens positioned under the
ball). Use cotton rods or similar. A flexible
protective keyboard membrane (WetEx
