I can't find caption option

[TITAN7274]

I have recently bought Samsung 43" N5470 smart tv. But I can't find any caption option in the accessibility. Is there any way to find it out and turn on caption/subtitles while watching a movie on the television?

usually on your remote you sould see a button says sub or subtitles

If I turn on the subtitle button from the tv remote, the voice guide turns on
