How do you turn closed caption on/off on BrightSign players?

I have read the following posts:

https://brightsign.zendesk.com/hc/en-us/articles/218065197-Do-BrightSign-players-support-closed-captioning-or-subtitles-

My question is how do you turn CC on/off on a BrightSign player? Does it involve the distribution of a new presentation to the player?
