I recently purchased a Rockwood Minilite 2304KS. It came with a IRV 34 multimedia receiver and a Furrion fehs24t8a led hd tv. I decided to watch a DVD yesterday and there were subtitles or closed captioning on the screen. I have not been able to figure out how to turn the closed captioning off. On the Furrion tv the closed captioning control is not active in the set up menu. And on the IRV 34 I cannot figure out how to display the irv34 system set up menus on the tv screen. Please help. Thank you!
