For IPTV Customers:
Click the CC button located at the bottom left of your remote.
Though there are a handful of CC options, only “Analog CC 1” & “Digital CC 1” will display proper closed captioning. If you miss the option, you can continue to hit the button to go back through the list. To turn off the feature, click the CC button until it displays “CC Off”. To see if the channel itself supports closed captioning (not all do) hit the info button and look for a white icon showing “CC”. If no icon displayed then no closed captioning is available for this channel.
For Digital Cable Customers:
Press the Menu button twice
Select “set up”
Select “closed caption setup”
Press the arrow to the right of the OK button to change from off to on
Then press exit – closed caption will then be turned on
