As far as I know, this reciever is the same basic design as the Manhattan Starlight series, If so, press "Menu" and navigate to "System Information" in the "System" submenu.
On my Startlight it reports Boot, APPL and C.A. version numbers.
Hope this helps.
If not, here's a potentially useful site

The Italians and Dutch in particular are heavily into Fortec Star (and Manhattan Starlight) recievers. If you can manage the language barrier, there is a wealth of information on this site and others which is not always available in the UK.
