BEFORE INSTALLATION

1. Make sure you have positioned the booster close enough to an existing electrical outlet.

2. Ensure adequate separation between the planned locations of the booster and inside antenna (at least 30

ft.). A separating wall between the booster and inside antenna is ideal. (See page 8).

3. Make sure you have sucient cable length between the inside antenna location and booster location. The

provided cable is 50 ft.

Installation Overview

Step 1. Find the window that has the strongest signal. Note that the EZ 4G and the tabletop antenna should

have a separating wall.

a) If installing in a two story home or oce place the EZ 4G upstairs and install the inside antenna

downstairs.

Step 2. Mount the signal booster, connect the inside antenna cable to the signal booster, and connect the

booster to an AC power source.

a) For optimum performance, place the EZ in a corner of the window.

Step 3. Install the inside antenna.

Step 4: Connect power.

EZ 4G INSTALLATION

Step 1. Find the area with the Strongest Signal

Before installing the booster, nd the area in your home with the strongest possible cellular signal.

Note: Window lms that block UV rays may also block cellular signals. When using a booster in a home

comprised of lm-coated windows, the booster may perform better when placed against a wall facing the

exterior of the home.

The signal booster requires a minimum cellular signal of low –100 dBm to high –90 dBm.

Signal readings usually appear as a negative number (for example, -85). The stronger the EZ signal, the closer

it gets to zero. Aim for a signal between -65 and -85 dB. Signals stronger than -50 dB may cause the booster

to shut down. Find the area with the strongest cellular signal source from your service provider by following

the directions below. You can also go to www.antennasearch.com to nd the general location of your carrier’s

towers.

Select a window sill location away from buildings, walls, trees, hills, and other terrain features that can block or

reect wireless signals with the strongest signal.
