How It Works
SureCall’s EZ 3G and EZ 4G are high-quality bidirectional signal boosters that enhance
cellular signals to areas that are prone to weak cellular coverage.
EZ works with two antennas:
• An inside desktop antenna that communicates with your cell phone.
• An antenna built into the back of the booster that communicates with the cell tower.
Signals sent from a cell tower are received by EZ 3G or EZ 4G, amplied and then
broadcast to your phone via the inside antenna. When your phone transmits, the signal
is sent to the inside antenna, amplied and then sent to the cell tower via the EZ 3G or
EZ 4G.

Step 1. Make sure you have positioned the booster in a window with the strongest
signal close enough to an existing electrical outlet.
Step 2. Make sure you have sucient cable length between proposed inside antenna
location and booster connector.
Installation Overview
Step 1. Find the window that has the strongest signal (See page 7 for instruction).
Step 2. Mount the signal booster, connect the inside antenna cable to the signal booster, and connect the booster to an AC power source (See page 9 for instruction).
Step 3. Install the inside antenna (See page 8 for instruction).
Step 4. Congure gain settings on the signal booster if needed.

Installing Your Hardware
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 close to -50 dB. Signals stronger than -50 dB may cause the booster to shut down (see the graph below). Before install­ing the outside antenna, nd 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.
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
2. 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.
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.

Installing Your Hardware
Step 4. Install the Signal Booster
1. Select a location close to a working AC outlet. Do not expose the signal booster to excessive heat, direct sunlight, moisture, and airtight enclosures. In areas where there are higher temperatures, install the booster vertically, so air can move between the metal channels on the faceplate.
2. Use supplied screws or appropriate screws for surface of mounting location and drill through screw tabs holes on boosters.
3. Connect the inside antenna cable to the signal booster connector marked INSIDE (see page 14). 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. Turn the booster’s power switch on.
• The signal booster turns on automatically.
• The Power LED lights up 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 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.
1. The back of the booster should be pointed in the direction of the nearest cell tower.
Go to www.antennasearch.com for information.
2. Place the table-top antenna in a central location at least 20 feet from the booster.
3. To set the attenuation value please use the chart below for reference. Distance between
antenna and equipment
4. The equipment must be restarted when attenuation adjustments are completed.

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.

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.
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 outside antenna.
• Storage and transportation: Store and place in non-extreme room-temperature and dry environment
• Attention: This antenna should not be used near open re or ame
Warning: Window lms that are used to block UV rays also block cellular signals. When using a cellular signal booster with a home comprised of
lm-coated windows a booster that comes with an outdoor antenna must be used.

Step 5. Congure Gain Settings
1. EZ 3G : Find the PCS and Cellular dials on the top of the signal booster.
2. EZ 4G : Find the LTE-A, LTE-V, PCS, Cellular and AWS dials on top of the signal booter.
Set the dials according to the coverage area and the distance between the indoor antenna and boost.
If you Want to Improve Coverage
• Find a location that receives a stronger signal and relocate the booster to that location.
• Increase the distance between the booster and inside antenna.
• Be sure your signal booster’s dB gain is turned up to maximum gain on each dial.
Warning: Do not adjust the uplink and downlink dB attenuation settings more than 20dB, this could
cause the booster to shut down.

The red LED goes ON.
The Power LED does not turn ON.
Yellow/Red Flashing LED
The Alert LEDs continue to ash.
Your signal booster has no power.
More antenna separation is needed. If you cannot provide more antenna separation and the Alert LEDs ash after the initial activation period, lower the dial above the blink­ing LED by 5dB (for example, from 50 to 45) and monitor the bars on your cell phone to see whether reception improves.
Be sure the AC outlet is working and is not controlled by a wall switch that can cut power to the outlet.
Oscillation is detected. First try increasing the separation between the indoor and outdoor antennas. If this doesn’t eliminate oscillation, lower the dB gain in 5dB incre­ments.
The signal booster shuts down automatically, and then restarts after 60 seconds. Turn down the PCS or Cellular dial that is oscillating to prevent the signal booster from shut­ting down automatically. This may indicate that additional antenna separation is needed.
Verify that the switch on the power supply is turned on and Green 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 sup-
ply to SureCall. Contact tech support at 1-888-365-6283 or support@surecall.com, or go to www.surecall.com and log on to online support to receive an RMA.
Troubleshooting
Red Flashing LED
Your signal booster restarted and shut down for 15 minutes, and is now shut down permanently.
Signal coming into booster from cellular tower is too strong causing the booster to automatically shut down. There are two possible solutions:
1. Add an inline attenuator to the cable coming into the booster
2. Relocate the EZ booster to a location where the signal is weaker.
Each SureCall signal booster is equipped with Auto Shutdown to prevent cell tower interference. The outside antenna may be close to a cell tower. Move the outside antenna to a location that provides sucient distance from the cell tower to prevent the signal booster from automatically enabling Auto Shutdown. Once away from the original location.

Problem Resolution
Signal booster has no power
After installing your signal booster system, you have no signal or reception.
Verify that the booster switch is turned on. Connect the power supply to an alternate power source. Be sure the AC outlet is working and is not controlled by a wall switch that can cut power to the outlet. If the green POWER LED on the signal booster is OFF, return the power supply to SureCall. Contact tech support at 1-888-365-6283 or support@surecall.com, or go to www. surecall.com and log on to online support to receive a Return Merchandise Authoriza­tion. (RMA)
Check the strength of the outside signal as close as you can to the outside antenna. (see instructions on page 14)
Double-check all signal booster and antenna cable connections.
Be sure your signal booster’s dB gain is turned up to full power on each dial. (see page 8)
