Your Color Processor must be connected to video equipment that has separate
audio and video jacks, such as a VCR, video disc player, or a true TV

To use this unit with a regular TV (with only VHF/UHF terminals) you must
connect an BF modulator between the Color Processor and lhe TV, to convert
the sjgnals to regular VHF TV signals. Radio Shack's Video Slabilizer/RF
