Can't monitor TV viewing all the time?
Use the parental controls in your cable set-top box to block programs by channel, title, rating, or time and date. You can also block pay-per-view and video on demand purchases.
It's easy. Click the "Menu" or "Settings" button on your remote and access the "Main Menu" to begin. Get more instructions for your cable set-top box here.
Don't have a set-top box?
You may be able to block programming with your TV's V-Chip. Your cable company may also be able to install blocking equipment if you don't have a set-top box.
