The AUDIO CC button on the remote control is a dedicated button to help you set preferences for your audio language and closed captions.
While watching live TV or a recording, pressing AUDIO CC displays the Audio / Closed Captions screen, which allows you to:
• Select the language for your audio. Some available languages may not be broadcast in stereo; changing digital audio options cannot override this status.
• Toggle closed captions (on or off), select a caption service, and format caption appearance
