Before You Begin.
Step 1
Find the spot with the best 3G/4G coverage:
The rst step in setting up your Cel-Fi system
is to nd the spot in your home or oce that
has the highest 3G/4G signal level by using
your phone (3G/4G 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 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 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.
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.
