Before installation, please note the following important factors:
1. A minimum of 25 ft. of separation is needed between the outside and inside antennas.
2. The booster should be positioned close to an electrical outlet.
3. Ensure sufficient cable length between planned outside antenna location and booster.
Step 1. Find the Area Outside with the Strongest Signal
Before installing the outside antenna, find the area with the strongest cellular signal from your service provider by following
the directions below:
Measure the strength of the outside cellular signal in various locations.
• Apple iPhones: Dial *3001#12345#* and press Call. In the top-left corner, a dB 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 find other cell signal measurement apps.
• Internet: go to www.speedtest.net to test 3G and 4G data rates.
This signal booster requires a minimum cellular signal reading of –100dB at the location of the outside antenna. Signal
between -70dB and -90dB is recommended for best performance.
Please note: Signal stronger than -50dB may cause the affected frequency bands to shut down.
Step 2. Install the Outside Antenna
Once you have located the area of strongest signal, mount the antenna to a pole or pipe (not included) at the highest
possible elevation. The directional Yagi antenna works best when facing the direction of your carrier’s cellular tower. To
find the location of your carrier’s closest cell tower go to www.cellreception.com.
To install the outside antenna, assemble the u-bolt, bracket, nuts and washers as shown in the illustration. Keep the
connections loose enough to allow the antenna to rotate until the optimum direction is found.
Note: The outside antenna may be installed on a variety of pipe angles. Ensure that the mounting area has at least a
12-inch radius clear of obstructions and other radiating elements and orient the antenna vertically with the drip hole at
the bottom.
Once the outside antenna is secured to a pipe or pole, connect one end of the provided RG6 coax cable to the antenna
and tighten the connection.
Step 3. Assemble the Signal Booster and Inside Antenna
Connect the inside antenna to the booster by screwing it directly into the port of the booster labeled “INSIDE”. Next, select
a location for the booster that is close to a working AC outlet*. Because the supplied inside antenna is omni-directional
(i.e. it broadcasts signal in a 360º radius), the booster should be placed in a central location with the antenna oriented in
an upright position.
Should you choose to mount the booster to a wall, screws have been provided. Use the supplied screws or appropri-
ate screws for surface of mounting location and drill through screw tab holes on booster (see
Booster Components
Diagram
illustration).
Connect the remaining end of the RG6 coax cable to the booster port marked “OUTSIDE” and tighten the connection.
Step 4. Connect Power
Next, connect the AC power cord to the booster and plug into a 110V AC power outlet. Once the booster has been
completely assembled, turn the booster’s power switch on.
Note: If the Power LED does not turn ON or the Alert LEDs continue to flash, see the Troubleshooting section. 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.
Gain Settings
The SureCall gain dials should always be at maximum level unless the control light in a specific band is flashing red or
flashing red-yellow. In either of these cases, the first action should be to increase the antenna isolation between the inside
and outside antenna as much as possible and restart the booster. If the situation continues, you can lower the gain with
an attenuator or, as the last resort, reduce the booster gain by 5dB at a time until the control light in the frequency band
flashes yellow.
If you Want to Improve Coverage
1. Find a location that receives a stronger signal and relocate the outside antenna to that location.
2. Optimize the Yagi antenna angle.
3. Increase the distance between the outside antenna and booster.
4. Set each dial on the booster to maximum gain.

LED
Condition
Indication
Yellow
Solid
Indicates that the band is Inactive. After a period of time, if there’s no activity the band will go into sleep
mode. Light is off while band is active. This is part of normal operation.
Yellow Flashing
Indicates that the Automatic Gain Control (AGC) is self-adjusting. This is part of normal operation.
Red
Flashing
Indicates that the booster is receiving too much signal which could cause the affected band to
automatically turn off. When this happens:
1. For kits using an OMNI outside antenna, relocate the outside antenna to a location where the signal
is weaker.
2. For kits using a YAGI outside antenna, turn the antenna in short increments away from the signal
source.
3. Add an inline attenuator to the cable coming into the outside port of the booster.
4. Though not desirable as amplification will not be optimum, lower the dB gain setting in small incre-
ments until the light turns off or flashes yellow.
Yellow/
Red
Alter-
nately
Flashing
Oscillation is detected.
First, try increasing the separation between the inside and outside antennas. If your booster kit uses
two directional antennas (example: outside Yagi antenna and inside panel antenna), ensure that they
are facing away from one another.
If oscillation continues, lower the dB gain in small increments until the light turns off or flashes yellow.
Red
Solid
Band is off.
If a red light has been flashing for an extended time, the band will automatically shut off and display a
solid red light.
This can also happen when the gain dial for a frequency band has been turned all the way down or, for
products that use switches, attenuation greater than 25 dB has been made.
WARNING: Do not attenuate the uplink and downlink dB settings below 35dB. This could cause the affected frequency band to
turn off.

would have to be reduced by 3.5 dB, especially where the output signal is re-radiated and can cause interference to adjacent band users. This power
reduction is to be by means of input power or gain reduction and not by an attenuator at the output of the device.
Troubleshooting
Problem
Resolution
Signal booster has no power
Connect the power supply to an alternate power source.
Verify that the power source is not controlled by a switch that has removed power from the
outlet.
If the POWER LED on the signal booster is OFF, return the power supply to SureCall. Contact
tech support to receive an RMA at: 1-888-365-6283 or support@surecall.com
After completing installation, indoor
signal coverage has not improved
(1) Verify that all cable connections are tightly fitted. (2) Try further separating the booster and
antenna. (3) Verify that there is usable signal where the outside antenna 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.
