I just had a Dish Network 222k receiver installed in my motorhome. I only have one cable from the Wingard Dish to the receiver. My understanding is that I can’t use the dual mode setup. I’m OK with that. I do want to be able to control the receiver from the bedroom using the remote2 in UHF mode. (The infrared sensors in my MH are not working at this time.) Is that possible? Do I have to set the receiver in shared mode?
