o.k I recently bought a UHF remote to use at the TV1 location so I could put the receiver behind a cabinet. I went in an enabled for UHF and changed the address for remote 1 to 6. The remote works fine as an IR remote but the UHF function does not work. If I close the cabinet or go to another room the remote does not function. What am I doing wrong? The UHF remote for TV2 works great.
