Or set the MRF-260 to 0 (not the remote) and start pressing buttons on the remote. Watch the activity LED on the 260. It will flicker when you press a button on the remote. If it still flickers after you quit pressing buttons on the remote, then you have interference and will need to play around with different locations. possibly even remove the antenna on the 260 to see if that helps.
