Things You'll Need
Instructions
Disconnect your home cable service's coaxial cable from the cable port on the back of the television.
Connect the RF Switch's coaxial cable to the television's cable port. The end connector on this RF switch cord will look exactly like the connector you just removed from the television.
Reconnect your home cable line to the plug located on the back of the RF Switch box.
Connect the remaining cord--a thinner cord extending from the side of the RF switch's box--to the RF out port on the back of the SNES.
Switch the channel switch on the back of the SNES console to channel 3 or 4. This will be dependent on your preferences and what works best for your television.
Turn on your television and turn to the channel you indicated on the RF channel switch.
Power on your SNES.
