how to enable close caption on T2 Prime?

Hello Friends, I was wondering if close caption can be enable on T2 prime?

Thanks:)
I think by pressing one of the colored buttons while on a TV channel the option may be there (the red button maybe).
But it may not allow the function (doesn't allow the change), last I remember.
 
IDK. But,.........you will have to go through all of the various box menus. There is also a menu for the main operating system after you exit all of the programs, maybe it's in there somewhere?
