The current settings of these parameters can be viewed at any time, but to change their setting values an authorized login

edit page for the parameter) and the user is not currently logged in, a warning is displayed indicating that a login is
required (see Fig. 29).

If the user is authorized to change configuration settings, knows the display password, and wishes to continue with the
parameter change, the user presses the OK button with the input focus on the “Yes” selection. If the user isn’t authorized
to change the parameter or doesn’t want to change it, the user tabs to the “No” selection with the right arrow or left arrow
button and presses the OK button. Control returns back to the previous page if the user elects to not make the parameter
change. If the user elects to change the parameter setting, the user is asked to login (see Fig. 30).

button to login. A successful login transitions to the configuration page. An unsuccessful login (wrong password) displays
an “INVALID PASSWORD” message (see Fig. 31). If the user elects to cancel the login, tabbing to the “No” command and
pressing the OK button returns control to the previous page.
