There are a number of default states and agencies that come pre-programmed in the radio, as was mentioned in another thread. You can download everything, then in FS, when you are ready to upload your own programming, there's an option to Erase everything before proceeding. This insures that you are starting from a 'clean slate' and preserves some memory - after all there are states on those defaults that you will never hear from Oklahoma :.>>
Oh and by the way - the link for the user guide that was given earlier is also available to you (as long as you're online) by selecting Help/Online Help from the toolbar
