Rescan Your DTV Converter Box
After hooking up your DTV converter box, you will need to run the "scan" function to allow the box to find and "remember" the available digital channels.
You should also rescan periodically since new channels are sometimes added. In addition, some channels may increase their signal strength, allowing you to receive channels that were previously too weak or far away.
Double Rescanning
In some cases where stations moved their digital frequencies on June 12, simple scanning may not be enough. There is a procedure – sometimes called "double rescanning" – that can clear your box's memory of saved channels. These earlier scans may have saved channel information that is now incorrect.
There are five simple steps to a double rescan for a converter box or digital TV, which are as follows:
- Disconnect the antenna from the box or digital TV.
- Rescan the box or digital TV without the antenna connected. As with any scan, follow the on-screen instructions or owner's manual for your device.
- Unplug the box or digital TV from the electrical outlet for at least one minute.
- Reconnect the antenna to the box or digital TV and plug the unit into the electrical outlet.
- Rescan the box or digital TV one more time.
