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:
• An antenna built into the back of the booster communicates with the cell tower while it sits in
your window.
• An inside desktop antenna or optional panel antenna that communicates with your cell phone.
• Signals sent from a cell tower are received by EZ 4G, amplied and then broadcast to your
phone via the inside antenna. When your phone transmits, the signal is sent to the inside an-
tenna, amplied and then sent to the cell tower via the EZ 4G.

Warning:Unauthorized antennas, cables, and/or coupling devices are prohibited by FCC new rules. Please contact FCC for details: 1-888-CALL-FCC.
Changes or modications not expressly approved by SureCall could void the user’s authority to operate the equipment.

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
(see page 8).
3. Make sure you have sucient cable length between the inside antenna location and booster location.
Installation Overview
Step 1. Find the window that has the strongest signal. Note that the EZ 4G and the desktop antenna should
have a separating wall.
a) If installing in a two story home or oce 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.
EZ 4G INSTALLATION
Step 1. Find the area with the Strongest Signal
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
reect wireless signals with the strongest signal.
Measure the strength of the existing cellular signal in various locations
• Apple iPhones: Dial*3001# 12345#* and press Call. In the top-left corner, a number appears instead of
bars.
• Android devices: download apps such as “Network Signal Info” in the Google Play store to measure
signal strength. Search check real signal strength to nd other cell signal measurement apps.
• Internet: go to www.speedtest.net
Before You Install
Installing Your Hardware
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.

Step 2. Install the Signal Booster
1. Select a location close to a working AC outlet, noting that the back of the booster should be pointed in
the direction of the nearest cell tower (Go to www.antennasearch.com for information.). Do not expose the
signal booster to excessive heat, direct sunlight, moisture, and airtight enclosures.
2. Choose the appropriate installation method for your application (either the supplied window sill stand or
mounting tape if no window sill is present).
3. Connect the inside antenna cable to the signal booster. Hand-tighten the connection.
4. Connect the AC power cord to the signal booster.
5. Connect the plug on the other end of the 110V AC power outlet.

6. The signal booster turns on automatically.
• The Power LED lights up green to show that the signal booster is ready for use.
• The Alert LEDs ash 5 times on each band to show the band is activated.
Note: If the Power LED does not turn ON or the Alert LEDs continue to ash, see ”Troubleshooting” on page 12.
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.
Step 3. Install the Inside Antenna
For areas of 1,000 square feet and below allow 30-35 feet of separation between the booster and the desktop
antenna (minimum separation is 20 feet).
Please note: The range of the antenna is dependent on three factors:
1. Physical obstructions,
2. Power generated by booster
3. Reception from outside signal received and distributed by EZ 4G
Option A: Inside desktop antenna
Place the inside antenna in a central location where signal is needed.
Important:
• Window lms that are used to block UV rays also block cellular signals. When using a booster with a home
comprised of lm-coated windows, a booster that comes with an outdoor antenna must be used.
• This antenna should not be used near open re or ame.
• Storage and transportation: Store and place in non-extreme room-temperature and dry environment

Installing Your Hardware
FCC 27.5 (d)(4) Statement: Fixed, mobile, and portable (hand-held) stations operating in the 1710-1755 MHz band as well as mobile and
portable stations operating in the 1695-1710 MHz and 1755-1780 MHz bands are limited to 1 watt EIRP. Fixed stations operating in the
1710-1755 MHz band are limited to a maximum antenna height of 10 meters above ground. Mobile and portable stations operating in
these bands must employ a means for limiting power to the minimum necessary for successful communications.
Option B: Inside Panel Antenna
Choose a location for mounting the antenna on vertical surface. Ideal height o the ground or oor should be
the approximate height of your cell phone when in use.
1. Using plate, mark position of desired screw placement with pencil or marker.
2. Screw mounting plate into place with the slide panel protruding towards you.
3. Slide antenna securely onto mounting plate.
Note: Be sure to provide enough separation from outside antenna. Panel antenna should not face outside antenna.
