BEFORE You Begin

Step 4

If you can nd a place in your home that gets at least one bar of 3G, 4G, LTE

signal, the revolutionary Cel-Fi DUO Smart Signal Booster system may bring you

smoother video and surng, and improved voice coverage throughout your home.

Cel-Fi DUO Smart 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 Smart 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, 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, 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.

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 farther away from the

Network Unit (see below).
