Introduction
Congratulations on purchasing the SureCall Flex 2Go kit, the finest cellular
amplifier available for your vehicle!
SureCall adjustable cellular boosters and kits remove the frustration over dropped calls,
limited range, and slow data rates by amplifying incoming and outgoing cellular signals
in vehicles. The Flex2Go is designed with leading-edge technologies to detect and
amplify weak incoming signals your cellular device would otherwise miss and to
broadcast a significantly stronger signal back to the cell tower.
This guide contains all the information you need to get your SureCall Flex 2Go booster
system up and running.
Principles of Operation
The SureCall Flex 2Go is a high-quality bidirectional amplifier that boosts cellular
signals for cars, motorhomes, and other vehicles.
The Flex 2Go works with two antennas :
An inside antenna that communicates with your cell phone.
An outside antenna that communicates with the cell tower.
Signals sent from a cell tower are received by the outside antenna, amplified by the
booster and then sent to your phone via the inside antenna.
When your phone transmits, the signal is sent to the inside antenna, and then sent to
the cell tower via the outside antenna.
Some cell signal is required for the Flex 2Go to enhance cellular signal coverage.
The weakest cell signal for the Flex 2Go to work is low -100dBm to high -90dBm.
dBm is an abbreviation for the power ratio in decibels of the radio power per one
milliwatt and indicates cell signal strength.

Installation Instructions
The Flex 2Go booster kit is suited for installation in a vehicle or motor home.
Refer to the figure below when performing the following procedures.
Step 1: Connect the Outside Antenna
1. Mount the magnetic antenna in a location that:
Is on top of the vehicle.
Has at least a 12-inch radius clear of obstructions and other radiating
elements, such as a radio antenna.
Is at least 4 - 6 feet from the inside antenna.
2. Using the supplied cable, connect the outside antenna to the booster
connector marked OUTSIDE.
3. Run the outside antenna cord under front door insulation lining to hide and
protect antenna cable. Wrap up any loose cable.
4. Hand tighten the connection.
Note: The outside antenna must not be co-located or operating with any other
antenna or booster.
Step 2: Connect the Inside Antenna
1. Mount the inside antenna so it is:
Within 2-3 feet of the cell phone for best results.
Mounted on a surface that is at least 4” (10 cm) away from metal.

2. Using the supplied cable, connect the antenna to the booster connector
marked INSIDE (see page 4).
3. Hand tighten the connection.
Step 3: Mount the Booster
1. Select a location for your booster, such as under the driver’s seat.
Step 4: Connect to DC Power
1. Connect the Power Cord. Connect the DC power cord to the booster before
plugging it into the cigarette lighter adapter. Verify that all connections to the
booster are tight and secure.
2. Turn the power switch on the lighter adapter to the ON position.
The LED light glows, indicating that the booster is ready to use. The booster
turns on automatically.
The Power LED goes ON to show that the booster is ready for use (see
page 4).
If the Power LED does not go ON, be sure the DC outlet and adapter are
working.

If the red LED goes ON, it is the result of one of two factors.
1. More antenna separation is needed. Most likely, the easiest way to achieve
this is to move the magnetic mount antenna farther to the back of vehicle
away from the inside patch antenna.
2. Your vehicle is too close to a cell tower
If unable to provide more antenna separation and the Alert LEDs flash after
the initial activation period, lower the dial above the blinking LED by 5dB
(for example, from 50 to 40) and monitor the bars on your cell phone to see
whether reception has improved.
The booster case may become warm during operation. This is normal.
Press any key on your cell phone to refresh communication with the base
station.
WARNING. The booster is rated for 5-15V input voltage. DO NOT use the
booster with a higher voltage power supply. This can damage the
booster and/or cause personal injury.

Problem
Resolution
After installing the
booster system, you
have no signal or
reception where your
car is parked.
1. Check the outside signal closest as you can to
the outside antenna. To measure your existing
cell signal:
Apple iPhoneD: dial *3001#12345#*and press
Call. In the top-left corner, a number replaces the
bars.
Android devices: download apps to measure
exact signal strength, such as Network Signal
Info in Google Play store. Search "check real
signal strength" to find other cell signal
measurement apps.
2. Double-check cable connections to both
antennas and booster.
3. Be sure your booster's dB gain is turned up to at
least 40dB - 45dBon each dial.
One of the red lights
next to the dials on
your booster is
flashing.
1. Turn down the dB gain on the dial until the light
goes OFF or turns yellow.
2. Be sure the inside panel antenna is facing away
from the outside antenna.
3. Use the recommended 6-10 ft. of antenna
separation:
•50dB 30-40 ft. separation
•45dB 20-30 ft. separation
•40dB 10-20 ft. separation
•35dB 10 ft. separation

Problem
Resolution
Your booster restarted
and shut down for 15
minutes, and is now
shut down
permanently.
Each SureCall booster is equipped with Auto
Shutdown if there's danger of cell tower
interference. The location where your car is parked
may be too close to a cell tower. Drive to a location
that provides sufficient distance from the cell tower
to prevent the booster from automatically shutting
down. Once away from the original location, use
the power supply switch to restart the booster
manually.
Record the model and serial number for your products:
Serial #: ______________________________________________________
Purchase Date: ________________________________________________
If the booster interferes with your radio or other electronic receivers, move the
booster further away from those devices.
