Keyboard
Principle
The layout of the membrane keyboard is "English/USA international."
Warning
Maloperation
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 and softkeys F13 to 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 pressing keys other than the
configured ones.
Activating a key using a hard object, e.g. a screwdriver, reduces the life of the key.
Overview
The keyboard is divided into different functional groups:
• Function keys and softkeys
• Control keys
• Alphanumeric keys
• Numeric keys
• Cursor keys
