How It Works
SureCall’s Force5 2.0 cellular boosting function uses a high-quality bidirectional signal booster
that enhances signals to areas that are prone to weak cellular coverage. It works with two
types of antennas:
1) An outdoor antenna that communicates with the cell tower.
2) A set of Indoor antennas that communicate with your mobile devices.
Signals sent from a cell tower are received by the outdoor antenna, amplied by the booster
and then sent to your phone via the indoor antennas. When your phone transmits, the signal is
sent to the indoor antennas, and then sent to the cell tower via the outdoor antenna.

Booster Installation
Before Installation
Before installation, make note of these important factors:
• A “soft install” is recommended for each section of your installation before
permanent placement of parts.
• The booster will need to be close enough to an existing electrical outlet.
• A minimum of 50 ft. of separation between the outdoor antenna and indoor antennas is
recommended.
• There will need to be sucient cable length between planned outdoor antenna location and
booster connector.
• There will need to be sucient cable length between planned indoor antenna location and
booster connector. Additional cable may be purchased if needed.
Installation Overview
1. Find the outside area that has the strongest signal. (See page 7).
2. Install the outdoor antenna in the area identied in step 1. (See page 8).
3. Install the indoor antennas where increased signal is needed. (See page 11).
4. Mount the signal booster, connect the outdoor and indoor antenna cables to the signal
booster, and connect the booster to an AC power source. (See page 16).
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.

Installation
Section 1: Booster System Installation
Step 1. Find the Area Outside with the Strongest Signal
Finding Your Strongest Cellular Signal
To send and receive cell phone calls you need to have an adequate cellular signal. This usually
means having to be somewhat close to a cell phone tower. Your cellular signal is measured in
decibels (dB), which represents the power of the signal. Signal readings appear as a negative
number, for example -85 dB. The stronger your signal is the closer it gets to zero. As the
illustration below shows a -50 dB signal reading is very strong while a signal reading of -100
dB and above is very weak.
How to Determine Your dB Signal Reading
• Using an iPhone: Dial *3001#12345#*, a Field Test screen will appear press down on
the home button for a few seconds so your dB reading will appear in the upper left hand
corner.
• Using an Android: Download the “Network Signal Info” within the Google Play store. Once
installed, you will be able to view your dB strength.
• Internet: Go to: www.speedtest.net to test your 3G and 4G data rates.
• Alternatively, you may purchase a SureCall Signal Meter (SC-meter-01)* which detects and
displays the current signal levels.
*The SureCall Signal Meter may be used to read signal levels to identify the best location for an
antenna, as well as, identify the optimum angle at which to aim a directional outside antenna
when connected to the antenna using a provided cable.

Step 2. Install the Outdoor Antenna
After identifying the area of strongest signal, choose the surface where you will mount your
outside antenna. Before proceeding, please note:
A directional Yagi antenna works best when facing the direction of the nearest cellular tower
being used by your carrier
An omni antenna receives and sends signals in a 360º radius.
• For both antenna options, mount the outside antenna iand as high as possible and ensure
that the mounting area has at least a 12-inch radius clear of obstructions and other
radiating elements.
• For best performance, place the outside antenna at least 50 feet from the inside antenna
(see graphic “Antenna Separation”). Also note, Vertical separation is preferred as it is more
eective than horizontal separation.
• Always orient directional antennas to point away from other system antennas (see
illustration, “Antenna Aiming”).

Outdoor/ Indoor Antenna Separation
A minimum of 50 ft. of separation
between the outdoor antenna and
indoor antennas is recommended for
best performance.
Reducing antenna separation will
reduce the coverage provided by
the booster and generally, additional
separation will provide better
performance.
Antenna Separation
Option A. Yagi Antenna
Before installing a Yagi, or directional antenna, note that the antenna
should be mounted on a pole or pipe (not provided), at the highest
possible location and mounted horizontally, aimed in the direction of your
nearest cell tower. To nd the location of your carrier’s closest cell tower,
go to www.antennasearch.com.
Ensure that the mounting area has at least a 12-inch radius clear of
obstructions and other radiating elements and orient the antenna with the
drip hole at the bottom.
Once you have identied your install location, assemble the u-bolt,
bracket, nuts and washers onto a pole or pipe (not provided) as shown
in the illustration. Keep the connections loose enough to allow the
antenna to rotate until the optimum direction is found.

Booster Installation
Once the outside antenna is secured to a pipe or pole, connect antenna to cable connector
of end of the length of cable and run along route to planned
location of your booster.
IMPORTANT: For boosters enhancing AWS frequencies, the FCC has stated for consumer signal boosters
operating as a xed station in the 1710 - 1755 MHz uplink 2110 - 2155 downlink bands, the users or
installation manual must contain the 30 foot height restriction requirements per FCC 27.50(d)(4).
IMPORTANT: Do not collocate antennas or operate the outdoor antenna with any other antenna or signal booster.

Step 3. Install the Indoor Antennas
Indoor antennas for the Force5 2.0 come with one or more omni-directional (Dome or Ultra
Thin) or directional (Panel) antennas. One indoor cable is provided per antenna. For kits with
multiple antennas, a cable splitter and joining cable is also supplied.
• For omni directional antennas, mount on a ceiling in a central location where signal is
needed.
• For directional antennas, mount on a wall that faces in the direction signal is needed.
Option A: Indoor Dome Antenna(s)
The SC-222W wideband antenna is an omni-directional interior antenna that gathers and
sends signals from all directions. Range of antenna is dependent on three factors:
1. Physical obstructions
2. Power generated by booster
3. Signal level received by the outdoor antenna
Besides the antenna itself, parts include mounting equipment. It
should be mounted on a ceiling pointed down and in a central
location for best results. You can also install your interior antenna
above the ceiling panel provided there are not materials that could
obstruct signals.

Installation
Step 4. Install the Signal Booster
When placing the booster, select a location close to a working AC outlet. Do not expose the
signal booster to excessive heat, direct sunlight, moisture, and airtight enclosures.
1. Mount 24 inch x 24 inch, 3⁄4 inch thick sheet of plywood on top of sheetrock into wall
studs where the booster is to be placed. Plywood should be ush against wall. Once
mounted, screw the booster to the plywood sheet. The top side of the booster with the
lights and DIP switches should be facing away from the wall and plainly visible standing
near the booster.
2. Connect the outdoor antenna cable to the signal booster connector port marked OUTSIDE
and tighten the connection.
3. Connect the cable coming from the indoor antenna(s) to the booster port marked INSIDE
and 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.
Once the booster is powered on:
• The green Power light should illuminate.
• The band lights will ash red and yellow for approximately 10 seconds.
Note: If the Power LED does not turn ON or the Alert LEDs continue to ash, (see “Testing and Troubleshooting” on
page 20).This booster is rated for 5-20V 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.

Booster Conguration
The Force5 2.0 has 9 DIP switches and the frequency bands they utilize for attenuation. Below
the image is a general attenuation guide.
DIP Switch Conguration
By default, your booster ships with all DIP switches turned OFF to provide maximum gain
in all channels. This should always be your starting point whenever installing or reinstalling
the booster. When the booster is turned on, the band lights will ash red and yellow for
approximately 10 seconds.

Additive combination eects:
Switch 1 (1 dB) + Switch 2 (2 dB) = 3 dB attenuation
Switch 1 (1 dB) + Switch 2 (2 dB) + Switch 3 (4 dB) = 7 dB attenuation
Switch 1 (1 dB) + Switch 2 (2 dB) + Switch 3 (4 dB) + Switch 4 (8 dB) = 1 5 dB attenuation
Switch 1 (1 dB) + Switch 2 (2 dB) + Switch 3 (4 dB) + Switch 4 (8 dB) + Switch 5 (16 dB) = 31
dB attenuation
Adjusting Booster Attenuation
By default, all switches are turned OFF, meaning all frequency bands are operating at full gain.
• Turning a switch OFF increases booster gain for the selected channel.
• Turning a switch ON adds attenuation (reduced amplication) for the selected channel.
Switches should remain in the OFF position unless red ashing lights occur for a channel
or channels. Red ashing lights indicate that the system has detected oscillation for the
corresponding channel(s) and turn o if adjustments are not made.
Keep in mind when adjusting the booster: Full power is not always the best option. Your goal
is to obtain a usable cellular signal in as many areas of the building as possible. A successful
installation means that you can make calls without dropping and/or have a reliable data
connection.
Each bank of DIP switches contain ve switches. From left to right, the DIP switches in each
bank provide 1, 2, 4, 8, and 16 dB of attenuation (reduced amplication). These switches
are cumulative, meaning that the total amount of attenuation for a channel is equal to the
combined dB of all ON DIP switches in the corresponding bank.
A few practical examples:
• Turning all switches OFF = 0 dB attenuation (booster is at full gain).
• Turning ON Switch #1 in a bank = 1 dB attenuation (booster maximum gain is reduced by
1 dB).
• Turning ON Switches #1, 3, and 5 in a bank = 1+4+16 dB attenuation = 21 dB attenuation.
• In an 80 dB booster, this means the selected channel would be reduced to 59 dB (80 dB
-21 dB).
• Turning ON all switches in a bank = 1+2+4+8+16 dB attenuation = 31 dB attenuation
In an 80 dB booster, that means that the selected channel would be reduced to 49 dB (80
dB-31 dB).

Booster Controls
Testing and Troubleshooting
In the event you encounter a problem, follow the suggestions below to resolve the issue.
Once the booster is powered on (and no Warning lights are on), walk around the area to
assess the voice and/or data signal in representative variety of locations. Rene the antenna
locations and/or gain levels as needed, and then complete the permanent installation when
you are condent the system will perform well.
Remember: Bars are not always a reliable measure of signal. The best way to conrm signal
coverage is the ability to place and hold a call.
A few tips and some perspective:
• It’s not realistic to expect full reception everywhere in the building.
• As a general rule, increasing gain by 6 dB doubles the coverage distance of the interior
antennas. Start at the lowest gain and increase gradually as needed.
• If one or more red Warning lights comes on, it indicates there is oscillation in that band
and adjustments are needed.
• If you can’t get the coverage reasonably well-balanced, you may need to install an
additional interior antenna and/or a dierent type of interior antenna and/or relocate
interior antennas.
Problem Resolution
Signal booster has no
power
Verify that the booster switch is turned on.
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, [email protected], or go to www.surecall.com/support
After completing
installation, indoor
signal coverage has
not improved
Check the installation of your outdoor antenna. Ensure that the mounting area is
clear of obstructions and other radiating elements.
Check the outdoor signal strength at the site the outdoor antenna (see instructions
on page 7).
For kits that use a directional Yagi antenna, verify that the antenna is properly
aimed in the direction of your carrier’s closest cell tower (see page 8).
Verify that all cable connections are tightly tted to the booster and antennas.
