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 location in your home or oce

with the best 3G or 4G 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 oce. Make

sure 3G/4G icon is displayed on your handset.

Step 2

Plug in the Window Unit:

Plug the Window Unit into an easily accessible outlet near the

area with the strongest 3G/4G signal. (Note: Both of the power

supplies in your kit are identical.) Position the Window Unit so

that at least one bar displays on the signal strength indicator on

the front of the device. If you do not see at least one bar, try a

dierent location.
