Installation Manual
Before installation, ensure adequate separation between the locations of the outside antenna and Inside antenna – at least 25 ft.
1. FIND AREA OUTSIDE WITH STRONGEST SIGNAL
Using your phone, identify the outside location with the strongest signal. Generally, this is found on the side facing your nearest
cell tower and as high as possible.
Note that Bars are not always a reliable measure of signal. The best way to conrm signal coverage is the ability to place and hold
a call. For specic dB signal measurements, use the methods below. Note that dB measurements appear as a negative number
where the closer to 0, the stronger the signal (e.g., -100 dB would be considered a weak signal while -65 dB a strong signal).
Apple iPhones: Dial *3001#12345#* and press Call. In the top-left corner, a dB number appears instead of bars.
Android devices: download the app “Network Signal Info” in the Google Play store.
Please note: This signal booster requires a minimum cellular signal reading of -100 dB at the location of the outside antenna. Signal between
-70
dB and -90 dB is recommended for best performance. Signal stronger than -50 dB may cause the aected frequency bands to turn o.
2. INSTALL THE OUTSIDE ANTENNA
After identifying the area of strongest signal, choose the surface where you
will mount the outside antenna.
Using the provided plate and hardware, mount the antenna at the highest
possible elevation and allow a minimum separation of 25 feet from the indoor
antenna. Ensure that the mounting area has at least a 12-inch radius
clear of obstructions and other radiating elements and orient the antenna
vertically.
Once the outside antenna is secured, connect one end of the provided
50 ft. coax cable to the antenna and tighten the connection.
3. INSTALL THE SIGNAL BOOSTER AND INSIDE ANTENNA
Choose a location for mounting the directional panel antenna on vertical surface. The antenna should be at the approximate
height of your cell phone when in use and facing a central area where signal is needed. Please note: Be sure to provide enough
separation from outside antenna - at least 25 ft. Also, the outside and inside antennas should face away from one another.
Using the plate, mark position of desired screw placement and screw mounting plate into place with the slide panel protruding
towards you (see panel antenna illustration below). Slide antenna securely onto mounting plate.
To install the booster, select a location that is near the inside panel antenna and a working AC outlet*. Use the supplied screws
or appropriate screws for surface of mounting location and drill through screw tab holes on booster (see Booster Components
Diagram illustration) and mount the booster to a wall.
Connect the inside antenna and booster by connecting one end of the provided 20 ft. of coax cable to the inside antenna and
the other end of the cable to the booster port marked “INSIDE” and hand-tighten the connection.
Next, connect the outside antenna and booster by connecting the remaining end of the 50 ft. cable leading from the outside
antenna to the port of the booster marked “OUTSIDE”.
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 ash, 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
.
CONFIGURE GAIN SETTINGS
The SureCall gain dials should always be at maximum level unless the control light in a specic band is ashing red or ashing
red-yellow. In either of these cases, the rst 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 ashes yellow.

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 remains OFF, contact tech support at: 1-888-365-6283 or

After complet-
ing installation,

not improved
(1) Verify that all cable connections are tightly tted. (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 conrm signal coverage
is the ability to place and hold a call.

If you Want to Improve Coverage
1. Find a location that receives a stronger signal and relocate the outside antenna to that location.
2. Increase the distance between the outside and inside antenna.
3. Set each dial on the booster to maximum gain.
LED Indicators
Color Condition Indication
O
This is part of normal operation. Light is o while band is active.
Yellow Solid
This is part of normal operation. 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 o while band is active.
Yellow Flashing
This is part of normal operation. Indicates that the Automatic Gain Control (AGC) is self-adjusting.
Red Flashing Indicates that the booster is receiving too much signal which could cause the aected band to
automatically turn o. 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. Increase the separation between antennas (additional vertical separation works best).
4. Add an inline attenuator to the cable coming into the outside port of the booster.
5. As a last resort, turn down the dB gain on the dial until the light goes o or ashes yellow.
Yellow/
Red
Alternately
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 o or ashes yellow.
Red Solid Band is o.
If a red light has been ashing for an extended time, the band will automatically shut o and display a
solid red light.
This can also happen when the booster attenuation has been turned all the way down.
WARNING: Do not attenuate the uplink and downlink dB settings below 35 dB. This could cause the aected frequency band to turn o.
