If you can’t see any channels over 13, check the input mode on your TV. It should be set to CATV not Antenna.
Check all coaxial cables running in to your TV, VCR, Sound System, Etc, to be sure they are connected properly.
If your cable isn’t plugged in directly to your TV, check that the device the cable is plugged in to (such as a VCR or DVD Player) is plugged in and powered on.
You may have to program your TV to receive all the channels. Every TV is different, but generally you can access the program function using Menu, selecting your input type (CATV) and selecting channel search (or auto-search, memory, scan).
If that doesn’t work, call South Central Technical Support.
