  • Find the spot that has the best 3G coverage

    The first step in setting up your Cel-Fi system is to find the spot in your home or office that has the best 3G coverage. This is typically by a window, and if you are in a multi story building, upstairs windows are usually better than downstairs windows.   Next

  • Plug in the Window Unit

    Take the Window Unit and one power supply out of the box (both power supplies are the same, so grab either one). Plug the Window Unit in, and check to make sure that you can see at least 1 “Bar” on the display in the center of the device. If you do not see at least 1 bar, try a different location.   Next

  • Optimize the Window Unit Placement

    The number of bars you can see on the Window Unit makes a significant difference in the operation of the Cel-Fi system. Try moving the Window Unit to a couple of different spots to see if you can get better signal; the more bars the better. If the Window Unit will be placed on a flat surface, you can choose to snap on the foot (supplied in the box). Alternatively you may decide to use the wall mounting bracket (also supplied) in which case you will not need the foot.   Next

  • Place the Coverage Unit

    Now place the Coverage Unit in a convenient location at the other side of your home or office. Wait for the green “status light” on the side of the Coverage Unit to stop flashing (this could take several minutes). Make sure that you have a green light on the center of the display. If the light is red, try another location.   Next

  • Optimize the Coverage Unit placement

    It sounds funny, but the farther you separate the Coverage Unit from the Window Unit, the better the coverage in your home, so put the Coverage Unit as far away from the Window Unit as possible (if you go too far a red light will show on the display). The number shown on the side of the display gives you an indication as to the quality of the placement. Try two or three locations and find the spot that gives you the biggest number.
