10.  If the NSU password has not been disabled, a “Password needed box will    

appear.  For the user name type NSU.  Enter the password that you use to login 
to the web page. 

11.  A progress screen will appear.  When complete a message box that reports if 

the process completed successfully or not.  Successful programming takes 
approximately 10 seconds, unsuccessful programming can take as long as 2
