This RF Switch will only work for the original black rectangular bulkier edition of the SEGA Genesis model 1601. If you have the sleeker more squarish second edition SEGA Genesis system MK-1631 also known as the SEGA Genesis 2 please check out our SEGA 2 RF Switch or SEGA 2 AV cable.
Make sure the RF Channel switch on the back of your SEGA Genesis console is set to the same channel (either 3 or 4) as your TV.
This RF also works for NES and SNES.
