How to Hook Up a RF Modulator

By Traci Joy

If you have an older TV and are not ready to part with it, you will need an RF modulator in order to use many of the newer DVD players, VCRs and video games. You can do this by connecting these devices to an RF modulator and then connecting the RF modulator to your TV. This can be done in just a few simple steps, but must be done properly in order for everything to function together.

Things You'll Need

  • RF modulator
  • Coaxial cable
  • Audio/visual cables
  • Device you are connecting

Step 1

Unhook the coaxial cable that runs from your cable source to your TV and connect it to the "Antenna In" jack on your RF modulator.

Step 2

Take another piece of coaxial cable and connect it to the "Out to TV" jack on the RF modulator. Connect the other end of it to the cable input on your TV.

Step 3

Take the audio/video cables and connect them to the ports on the back of your RF modulator, matching colored ends with colored ports.

Step 4

Connect the other colored ends of the audio/video cables to your device, matching colored ends to colored ports.

Step 5

Locate the channel switch on the back of the RF modulator and select channel 3 or 4.

Step 6

Power on your TV, turn to the channel you selected on the back of the RF modulator, and then power on your device.

Tips & Warnings

  • Connecting a different device to the TV is as simple as disconnecting the audio/visual cables from one and plugging them into another. However, some gaming consoles may require that additional items be hooked up. See your user's guide for setup instructions.
  • Your device will not show on the TV if the channel you selected on the back of the RF modulator does not match the channel you select on your TV.
