At times, over-the-air viewers need to rescan to update channel reception. This can happen when new channels are launched, when television station transmission equipment changes, or at other times when television sets need revised information to receive local channels.
A rescan is an update to the television set by using the “menu” button to have the television re-tune all available signals. In many instances, if a station changes frequency, the television set needs to be instructed to “rescan” the frequencies to find any new ones now available. Specific rescan steps vary by manufacturer. https://www.fcc.gov/rescan is a resource for more information, including manufacturer details.
