hello carl. mikeys -yes it is an rf remote i believe the rc64rb (r=rf,b=backlit)-- so i'm told. i have entered the rf menu many times but when i hit select at the end the remote dose not function any more. i have clldirectv many times and went thru the setup with them. they sent me a new h21-100 ---same problem. there must be a trick i'm missing. any help would be appreciated. thanks mikeys
