This is why I got out IT field and why I wont help anyone with anything tech. It also why I told my dad dont get mom and ipad/iphone, because YOU will be explains thing to her over over again, cause I wont do it.
20 years later he is still explain same thing to her, she barely understand how to work tv, forget about concept remote need to be programed if tv changes or dish remote need to be replaced.
You had more patience they i did, I would just programed the remote explained nothing and left, and moved on The is no point explain thing to some people
