How It Works
SureCall’s EZ Call 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 amplies 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 amplies outgoing cell signal back to the tower.

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 sucient 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 Call and the tabletop antenna should
have a separating wall.
a) If installing in a two story home or oce place the EZ Call upstairs and install the inside tabletop
antenna downstairs.
Step 2. Mount the signal booster, connect the cable to the signal booster, and connect the booster to an AC
power source.
a) For optimum performance, place the EZ Call booster in a corner of the window.
Step 3. Install the inside tabletop antenna.
Step 4: Connect power.
EZ CALL 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 Call 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.
Before Installation
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.

• 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
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 Call 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.
Step 3. Place the Inside Tabletop 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,
Option 1: Apply the booster directly
to the window (ideally, at a window
corner) using the provided adhesive.
Option 2: Use the provided stand to
set the booster on the window sill
(ideally, at a window corner).

2. Power generated by booster
3. Reception from outside signal received and distributed by EZ Call
Important:
• 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.
Place the inside tabletop antenna in a central location where signal
is needed and at least 30 ft. from the booster location. Run the
provided cable from the booster to the inside tabletop antenna and
hand-tighten.

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 ash, 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.
Step 5. Enjoy Boosted Cell Signal
Place a call in the room where the inside tabletop antenna is located to conrm that your phone is receiving a
boosted signal from the EZ Call.
IF YOU WANT TO IMPROVE COVERAGE
• Test dierent booster locations to identify which receives the strongest signal and place the EZ Call booster
in that location.
• Try relocating one component (booster or antenna) to a separate oor (upstairs or downstairs).
• Increase the distance between the booster and inside tabletop antenna.
Please Note: Changes or modications not expressly approved by SureCall could void user’s authority to
operate the equipment.

Left Yellow Flashing Automatic Gain Control (AGC) is self-adjusting. This is part of normal operation.
Left Red Flashing The booster is receiving too strong of a signal which could cause the booster to automatically turn
o.
When this happens: Relocate the EZ Call to a window location where the signal is weaker.
Right Red Flashing Self-oscillation has been prevented.
If this happens: Increase the separation between the inside tabletop antenna and the EZ Call booster.
