I am sure that this has been posted before, but can someone please tell me how to change the set of remote codes on either the Humax HDR1000S or the Humax TN5000HD?
When I turn one box on they both come on!!

With one of the boxes (probably the TN5000HD) off at the mains press OK and zero together, instructions should then appear on screen, just select a IR channel number to assign the remote/STB pair.

Thank you Bob_Cat!! I'll give it a try when I get home.
