Cheryl its not really complicated, you get a divided boot bath at a store like walgreens, fill it about half way with water and put some epsom salts in it, then take one red lead from the tens unit with the pad off and put it in one side of the foot bath and then take the black lead with the pad off and put it in the other side of the foot bath. It will not electrocute you , you will feel increased strength of electrical pulses over dry pads and the epsom salts will make your feet feel better as well.
