Keyboard

Principle
The layout of the membrane keyboard is "English/USA international."
Warning
Incorrect operation
If you activate several keys simultaneously, a malfunction on the device cannot be excluded.
Activate function keys and softkeys only in sequence! Use "KeyTools" as described in the
chapter "Additional Drivers and Applications."
Applies after the deactivation of the "security features" of "Key Tools" or after the
deinstallation of "KeyHook":
When the additional function keys F13 and S16 are used, or when using your own key code
table, serious malfunctions of the user software can occur, because the key codes behind
the function keys can also be activated by activating keys other than the configured ones.
Activating a key using a hard object, e.g. a screwdriver, reduces the life of the key.
