Type your RADIUSdesk url into the menu bar of your browser. I will use http://rd01.wificity.asia/ as a sample. The first screen you will see is a log-in screen. Go ahead and enter your Username and Password to log in.
Once you are logged in you will see the RADIUSdesk Home screen.
On the Home screen you will see shortcuts to the Applets most used.
At the Top Left corner is a Menu Button with further Aplets as Items and sub-items on the fly-out menus.
Once you click on an Item a window opens on the Home screen and the window has a tab on the activity bar at the top to show which windows are already open.
