How to activate ir mode for new remote
My Wife has bad vision, so I got a new simple remote for her. But it requires ir mode to change cable channels. I am told there is an ir mode that needs activating. The menus I am told to search do not have that option anywhere. My xfinity remote is too complex for her including the voice command feature.
How do I switch to ir mode? This mode is used by most third party universal remotes.
