How It Works
SureCall’s EZ 4G is a high-quality bidirectional signal booster that enhances cellular signals to areas that are
prone to weak cellular coverage.
How it works
1. An antenna built into the back of the booster communicates with the cell tower while it sits in your window.
2. The booster amplifies the existing cell signal and sends it to the tabletop antenna.
3. The tabletop antenna rebroadcasts the signal indoors to all mobile devices within range.
4. The booster amplifies outgoing cell signal back to the tower.

Before Installation
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 sufficient 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 office 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. F
ind the area with the Strongest Signal
Before installing the booster, find the area in your home with the strongest possible cellular signal.
Note: Window films that block UV rays may also block cellular signals. When using a booster in a home
comprised of film-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 find 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
reflect wireless signals with the strongest signal.

Android devices: download apps such as “Network Signal Info” in the Google
Play store to measure signal strength. Search check real signal strength to find
other cell signal measurement apps.
•
Internet: go to www.speedtest.net
Step 2. Install the Signal Booster
Once you have determined the inside location with the strongest signal, place
the booster in that location. Choose the appropriate installation method for
your application (either the supplied window sill stand or mounting tape if no
window sill is present) and connect one end of the provided cable to cable
connector on the booster. Note that the EZ 4G booster performs best when
placed at a window corner.
Note: Do not expose the signal booster to excessive heat, direct sunlight,
moisture, and airtight enclosures.
Option 1: Apply the booster directly
to the window (ideally, at a window
corner) using the provided adhesive.
Step 3. Place the Inside Antenna
When placing the inside antenna, note that further separation between the
booster and inside tabletop antenna will increase booster performance.
The range of the antenna is dependent on three factors:
1. Physical obstructions,
Note: Where you install your booster in relation to the carrier’s cell phone tower also determines signal strength. Although
cell phone carriers try to place towers for maximum coverage, local ordinances and terrain features can restrict tower
locations, which can limit signal strength at your location.
Option 2: Use the provided stand to
set the booster on the window sill
(ideally, at a window corner).

Step 4: Connect Power
Once the booster and inside tabletop antenna are connected
and in place, connect the power cord to the signal booster
and plug into a power outlet.
Note: If the Power LED does not turn ON or the Alert LEDs continue to flash, see
”Troubleshooting” on page 11.
This booster is rated for 5-15V input voltage. DO NOT use the booster with a higher
voltage power supply. This can damage the booster, cause personal injury, and void your
warranty.
Connecting the Power Supply
Step 5. Enjoy Boosted Cell Signal
Place a call in the room where the inside tabletop antenna is located to confirm that your phone is receiving a
boosted signal from the EZ 4G.
IF YOU WANT TO IMPROVE COVERAGE
• Test different booster locations to identify which receives the strongest signal and place the EZ 4G booster
in that location.
• Try relocating one component (booster or antenna) to a separate floor (upstairs or downstairs).
• Increase the distance between the booster and inside tabletop antenna.

Resolution
Signal booster has no
power
Verify that the switch on the power supply is turned on and red LED is ON.
Connect the power supply to an alternate power source.
Be sure the power source is not controlled by a switch that can remove power from the outlet.
Check the green POWER LED on the signal booster. If it is OFF, return the power supply to SureCall.

After installing your signal
booster system, you have
no signal or reception
Verify that cable connections are tightly fitted to the booster and antenna.
Try further separating the booster and antenna.
Verify that there is usable signal at the window where the booster is placed.
Remember: Bars are not always a reliable measure of signal. The best way to confirm signal
coverage is the ability to place and hold a call.

specifications or which are not defective or not covered by this warranty.
Products sold by SureCall shall not be considered defective or non-conforming to the Buyer’s order if they satisfactorily fulfill the performance
requirements that were published in the product specification literature, or in accordance with samples provided by SureCall. This warranty shall
not apply to any products or parts thereof which have been subject to accident, negligence, alteration, abuse, or misuse. SureCall makes no
warranty whatsoever in respect to accessories or parts not supplied by it.
