I have three 6.3 Dish remotes. I programm the "SAT" for my 722 and the "AUX" for my Bell 5100. Think this is the only remote that will allow you to program the "AUX" key for another receiver. I am constantly have to replace batteries usually less than a month. I have several other Dish remotes 6.0 etc that I use for other receivers they last for several months. Dish has sent me replacement 6.3 remotes but they all seem to have the same short battery life. Has anyone else noticed this problem? Thanks.
