IBM NetVista 8363-WXX: Disable Password for Terminal Properties ?

Hi have buyed a IBM NetVista Thin-Client at eBay.
The Modell is: 8363-WXX (N2200W).

No i´m try to configure the Terminal Client. But in the
Terminal-Client there´s a password for the Properties-Tab. So i can´t
change Terminal-Connections or any other things.

Have anyone an idea how i can deactivate the password ? I have also
try to reset the terminal to firm-settings, with no success. I can
changed the network-properties without problems, but the other things
are safed by the password.

please help..

thanks a lot..
