Warning
Faulty 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."
The following applies when the "Security features" of "KeyTools" is deactivated:
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 pressing keys other than the configured ones. Further
information is available in the description of "KeyTools" on the supplied "Documentation &
Drivers" CD.
Activating a key using a hard object, e.g. a screwdriver, reduces the life of the key.
