I recently had a genie installed with a mini genie in one room and then an HD H25 in my kids room so that we could take it with is on vacation or my parents vacation house at the beach. I wanted to test this out so that I don't get 5 hours away and have a problem so I took the H25 to my friends house. We hooked it up with no other receivers being hooked up but it kept saying problem communicating with dish 771A. I bring the receiver back home and it works just fine. I decided to unplug the genie for experimentation and then get the 771a error on the h25. Why is my h25 not working without the genie being on and why would I need the genie for the h25 to work somewhere else? Thanks
