Step 4
Place the Coverage Unit:
Place the Coverage Unit as far away
as possible from the Network Unit or
where you need coverage the most,
making sure that you have enough
distance between the two units. After
several minutes, the numeric display
will stop cycling.
If your device is set up properly, the green icons will appear on the display
as seen above. It is possible to place the Coverage Unit too close or too far
from the Network Unit. If this happens, a red icon will illuminate indicating
that you need to move the Coverage Unit either closer to, or further away
from the Network Unit (see below).
Step 5
Optimize The Coverage
Unit Placement:
The number on the front of the
Coverage Unit display indicates the
quality of the placement. For the
best service experience, move the
Coverage Unit around your home
until an 8 or 9 displays. Based on
the Coverage Unit number, you
may need to move farther/closer to
the Network Unit.
If you can nd a place in your home that gets at least one bar of 3G, 4G, or
LTE signal, the revolutionary Cel-Fi DUO Signal Booster system may bring
you smoother video and surng, and improved voice coverage throughout
your home. Cel-Fi DUO Signal Booster is a true plug-and-play system that
doesn’t require the installation of antennas or cables.
Step 1
Find the location with the best coverage:
The rst step in setting up your Cel-Fi DUO Signal Booster
is to nd the location in your home or ofce with the best
mobile network signal. Use your phone to identify the
area with the most bars of signal. Typically, the best
service will be near a window in the highest oor of
your home or ofce. Make sure a 3G, 4G, or LTE icon is
displayed on your handset.
Step 2
Plug in the Network Unit:
Plug the Network Unit into an easily
accessible outlet near the area with
the strongest 3G, 4G, or LTE signal.
(Note: the power supplies in your kit are
identical.) Make sure that at least one
bar is displayed on the signal strength
indicator on the front of the Network
Unit. If you do not see at least one bar,
try a different location.
Step 3
Optimize the Network Unit Placement:
The bars on the front of the device indicate the
strength of the mobile network signal in the area.
Moving the Network Unit to a different location in
your home may increase the signal, and can improve
the quality of your service.
