I have an Echostar Dishplayer and the 15-1994 remote does not have a code for it. I have use the learn feature to learn all the dishplayer remote codes to the 15-1994. I currently have Power configured to 1S. Can I have the actual power button on the 15-1994 learn the power button from the dishplayer. When I try to have it learn it doesn't flash rapidly when I click the power button. What buttons are fixed and can't learn anything?

Thanks
