Step 1
Find the spot with the best 3G coverage:
The rst step in setting up your Cel-Fi system
is to nd the spot in your home or oce
that has the best 3G coverage by using your
phone (3G icon must be displayed). This is typically by a window,
and if you are in a multi-story building, upstairs windows are usually
better than downstairs windows.
Step 2
Plug in the Window Unit:
Take the Window Unit and one power supply out of the box (both
power supplies are identical, so you can use either one). Plug the
Window Unit into an easily accessible outlet. 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 dierent location.

Step 4
Place the Coverage Unit:
Move to a location in your home where you need to have improved
coverage. Plug the Coverage Unit into an easily accessible outlet. Wait
until the numeric display stops cycling. This could take several minutes.
At this point you should see a green icon indicating
that the unit is working properly. It is possible
to place the Coverage Unit so far away that it
cannot communicate with the Window Unit. If
this happens, a red icon will illuminate indicating
that you need to move the Coverage Unit closer
to the Window Unit.
TOO CLOSE
A zero on the numeric
display indicates that the
Coverage Unit needs to
be moved farther away
from the Window Unit.
GOOD
This green icon indicates
that the Coverage Unit
is functioning normally.
TOO FAR
This red icon indicates that
the Coverage Unit needs
to be moved closer to the
Window Unit.
Step 3
Optimize the Window Unit Placement:
The number of bars you can see on the Window Unit make a
signicant dierence in the operation of the Cel-Fi system. Try
moving the Window Unit to a couple of dierent spots to see if
you can get a better signal; the more bars the better.
Step 5
Optimize The Coverage Unit Placement:
The farther away you place 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. The number shown on the side of the display gives you an indication as to
the quality of the placement. Test two or three locations and for best results; try and get
an 8 or 9 on the display.

The signal from the wireless network is too strong to use a booster.
Move Coverage Unit further away from Window Unit to achieve a coverage unit
number of 8 or 9 (even placing the Coverage Unit at the opposite end of the house). A
higher number means better coverage. You can also improve performance by moving
the Window Unit to a location with higher signal. The more bars the better!
