Autoscan worked straight away!!. Manual is easy to follow. Power everything off whilst connecting, then switch the power on your equipment i.e. TV/DVD/and the DTR2520/05. Autoscan will start on the screen and wait for it to complete.
Note; If you have an old style TV (one scart socket) you may (if applicable) find that you will have to press AV on your TV remote to see the freeview channels, then press AV again to view the standard analogue channels and vice versa.
If you know you live in a freeview area and your arial is modern mid or high gain, then you will have no problems with this unit and also, it is top up card optional. All in all no problems whatsoever with usage.
