Does it have built in Freeview?
If yes, you need to connect the aerial to it. If the TV also has freeview, you will then need to connect the aerial out from the recorder to the tv.
If it doesn't have freeview, then you will need to connect the freeview box or sky box or cable box to the recorder.
You then need to connect scart out from the recorder to the tv (or if the recorder has hdmi out, the connect that to hdmi in on the tv if the tv has it.)
