I get the message "To Be Announced" in the channel guide

When looking at the channel guide, if all you see for programming information is a message that says "To Be Announced", this is a normal message when first powering up your set top box, or after a power outage. It usually takes 10 minutes or so before channel guide information starts to appear, and a few hours for the full programming guide to download to the box. If "To Be Announced" has been displayed for longer than a day on every channel, power cycle the set top box and contact customer service if program listings don't appear within 20 minutes.
