It is necessary to rescan your analog-to-digital converter box anytime your antenna is adjusted or turned, you experience a loss of signal strength or a local channel is added in your area. Having the basic skills and instructions to perform a rescan will save you the headache of searching for the owner’s manual to your box or, worse, hiring someone to perform this simple task.
Press the “Menu” button on the remote control for the converter box.
Scroll through the options and choose the “Scan” or “Auto tune” option.
Wait for the box to scan for new channels, then “Exit” the menu screen. The rescan is complete.
