To enable/disable Closed Captioning on X1 boxes:
Press the Down arrow button on the remote control to launch the Trick-play bar.
Scroll to the left to highlight and select the CC soft key to enable/disable Closed Captions.
Press the Xfinity button on the remote control while viewing any screen to go to the Main Menu.
Highlight Settings (Gear icon) and press OK.
Highlight Accessibility Settings and press OK.
Highlight Closed Captioning.
Press OK to toggle the feature On or Off. If choosing On, then proceed to Closed Captioning Options and select your preferred settings (font size, color and formatting).
If you would like to choose your own font, background and window styling options, select Custom in the Closed Captioning Style field. If you wish to receive the Closed Captioning style chosen by the programmer for easy reading, switch the style to Auto.
Press Exit when finished. You must change the channel for the changes to take effect.
Closed Captioning (CC) can now be turned on or off using the voice remote from XFINITY. Simply press and hold the microphone (Mic) button, and say "Turn on Closed Captioning" or "Turn off Closed Captioning.”
Turn Closed Captioning On or Off While Watching a Program:
Every time the playback functionality options appear on-screen, a list of the accessibility settings currently enabled will be visible underneath the transport bar.
You can also check the status of accessibility settings directly from the playback controls. Reach the accessibility buttons by pressing down, and then the right or left arrows to reach the button of your choice.
If those options are collapsed, simply select the collapsed button, and it will expand to show all three accessibility buttons:
Video Description (D),
Secondary Audio Programming (SAP) and
Closed Captioning (CC).
