To be honest I haven't tried that, but I think you need satellite hooked up,
or the box will just say no signal and not respond!
You could try at home disconnecting your box from the satellite, by
removing your 2 incoming cables!
We have been doing this for years and currently take the IQ3 hooked up to sat dish as well as a VAST box for FTA channels.
A good sat meter is a marriage saver and Satplus Qld have some excellent ones.
