Need step by step directions to hook up a 16 bit Sega Genesis

There should be two plugs on the back of the sega. One for the power cord, and one for the audio/video cord. The audio/video cord is a coax cord with a little box in line. Hook your cable or antenna cable into the jack on the box and hook the end of the cable from the sega into your tv. There will be a switch on the sega or on the box somewhere that designates channel three or four, this is what channel your tv will need to be on to use the sega.
