Your TV must first be connected to the cable TV outlet in your room using a standard coaxial cable. RLH does NOT supply this cable. TV's that are not cable-ready may be able to receive channels 13 and below. Once everything is properly wired and plugged in, the TV must be setup for cable TV reception. This is usually done with a switch on the back of the TV, through a button on the TV or remote, or though on-screen programming.
Different brands use different wording.
You want to look for Cable, Standard, STD, HRC, IRC, Air, or Antenna. If you are using a VCR, it should be setup in a similar fashion. The TV should be set to channel 3 or 4 to interface with your VCR or cable converter properly. Please refer to your owner's manual of your TV, VCR, or cable converter on how to do this. Check the troubleshooting page if you are having problems.
