Technomate satellite receiver TM-2000 D.

No Remote.

I am unsure if this is working .
I don't use a TV Ariel and cannot connect it to one .
When I turn it on it just comes up with the number 0565 on the front . I don't know if this is an error code or if it's a channel number as when I press the channel up and down it does go up and down in numbers .

. And if it's an error code , is it just because it has no signal and so cannot boot up .
