Answer

 

On non X1 TV boxes:

 

The best way to turn on the Closed Captioning feature depends on what kind of Comcast device and TV you have. We've outlined a few of the different setups to help point you in the right direction.

*Note: Audio connections are not shown in the illustrations below.

 

 

Standard Definition TV with Standard Definition TV Boxes or DTAs:

• You’ll need to use the Closed Captioning features built into your TV. It is likely that the standard definition TV box or DTA is unable to send and receive Closed Captioning.
  

 

 

Standard Definition TV with High Definition TV Boxes (with or without DVR):

• You can use either the TV box or the TV to turn Closed Captioning on or off. If you accidentally turn Closed Captioning on in both, you'll see a double layer of captions.

 

 

High Definition TV with High Definition TV Boxes (with or without DVR):

• You will need to use the TV box. Closed Captioning should be turned off on your TV to avoid the chance of double layers of captions.
  

 

 

On High Definition TV with a CableCARD:

• You’ll need to use the CableCARD device to turn Closed Captioning on or off.
  

 

 

 

Steps to enable and disable Closed Captioning on non-X1 Motorola HD Set Top Boxes:

 

1. Turn STB off and leave TV on
2. Press Menu on STB or remote control
3. Using the down arrow, navigate to Closed Captioning
4. Press the right arrow to select Enabled or Disabled  

 

 

If you have a Scientific Atlanta or Cisco branded cable box:

 

 

1. Access the Main Menu by hitting the "Menu" button. 
2. Using the arrow keys, navigate to Setup and press OK/Select on the remote control.
3. Navigate to Closed Captioning Setup using arrow keys and press OK/Select. (On some TV boxes, this may be called Subtitle Setup instead. You may have to press the down arrow to navigate to the second menu screen to find this item.)
   
4. Using the remote control, modify the Closed Captioning and Background settings as needed, and press OK/Select to confirm the settings.
5. Please refer to the TV manufacturer’s instructions if this does not activate Closed Captioning.

 

If this does not activate Closed Captioning, try the following:
 

1. To access user settings (where you can manage Closed Captioning), turn OFF your set-top box; it will remain in standby mode.

1. Press (Guide) on your remote while the set-top box is in standby mode. OR press Channel Up + Channel Down simultaneously on the front panel of the set-top box.
2. Using the down arrow, navigate to Closed Captioning. Press the right arrow to select Enabled or Disabled

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.
