I am a new dish user. Have a 301's and a 501. I notice that on the remotes on both type of receivers that I have to push the buttons on the remote firmly to make it operate. When I push it sofly, the light flashes but the command does not reach the receiver. I can then push it softly again and the signal reaches the receiver. Basically, one firm push works first push. But it takes two soft pushes to work. The Dish remotes run my Sony TV volume fine with a soft push. My Sony remotes work the TV with a soft push. I have not used the Sony remote to control the Dish receiver. Is this normal behavior for the Dish 301 and 501? Does anyone know the code for the Dish 501 to use with the Sony programable remote?
