NOTE: Only one of the outside antennas is included in this kit (check model) All kits include necessary brackets
and co-axial cables for assembly. It is normal for the Amplifier to be quite warm while the phone is in use state.
To comply Smoothtalker warranty, this Amplifier must only be operated with cables, antennas, and coupling
devices that have been approved for use with this equipment.(Pg. 5)

Installation
1) Connect the outside antenna to the side of the Amplifier marked as
“outside antenna.”
Connect the inside antenna to the side of the Amplifier marked as “inside antenna.”
2) Placement
Placement: Place the outside antenna in the middle of the vehicle roof. If the
vehicle has a sunroof please place the antenna on the roof towards the back
window. Place the Patch(inside) antenna in desired location. For cars and trucks
the console between the front seats is recommended. Connect the Amplifier as
shown in Fig.1 & 2 on Pg. 1 or Fig. 3 on Pg. 4.
Important: Use only the power supply included with the Amplifier. Connecting
another power supply at any time will result in damage to the Amplifier and will
void the warranty. Do not turn on the power switch until ALL cables have been
screwed or plugged into the Amplifier or you can cause damage to the Amplifier.

The LED lights on the Amplifier face plate indicate the operating gain state of
the Amplifier.
The Green and Orange lights indicate the gain status in each operating band
When Both Green and Orange LED's are “SOLID ON” it means that the Amplifier
is operating normally with full gain (No Automatic Gain Reduction)
When one or both of the LEDS are flashing (Per the chart on Pg. 6) it indicates
that the gain has been automatically reduced due to either:
A) High receive (RX) outside signal level (when very close to cell tower)
B) Loop Oscillation, caused when the inside antenna is located too close to the
outside antenna
Each flash indicates 3dB of gain reduction also known as gain attenuation.
For example: three flashes equals 9dB of attenuation.
Green LED indicates loop oscillation status. When flashing it means reduction of
gain. To improve coverage you need to spread the distance between the inside
and outside antennas. If you spread them far enough away, the Green LED will
become SOLID ON which indicates the Amplifier is working at its max gain.

LED Lights Explanation and Troubleshooting
Orange LED indicates RX (outside signal) status.
There are 4 Orange LED lights: 800 Mhz , 900 Mhz ,1800 Mhz, 2100 Mhz.
LED ON state indicates that the RX (Receive Signal) function of the band is
functioning normally. LED OFF state indicates that the band is shut down.
When Orange LED is flashing it indicates reduced gain also known as
attenuation of gain. You cannot prevent this condition. It means that the outside
signal is very strong and the Amplifier has reduced it's gain in order to protect the
closest cell tower. If the cell tower which is close is the one you are using, then
you can ignore the gain reduction and you will still get enough signal strength
to cover your area. In this case this is the normal operating process.
If the close cell tower is not the one you are using, then you can try to relocate
your outside antenna away from this cell tower and face it or point it to the cell
tower you are using in order to get more gain.
If you need help pls contact [e-mail] and we will help
you determine your cell tower location and get you setup.

Each flash indicates 3dB of gain reduction also known as gain attenuation.
For example: three flashes equals 9dB of attenuation.
No Flashing = Full Gain
Each Flash = up to 3dB gain reduction
Each Flash = up to 3dB gain reduction

Operational description:
This devices comprise with International NPS (Network Protection
Standard): NPS and other compliance/safeguard features for AGC and
anti-oscillation have been implemented. NPS and other compliance/
safeguard features are defaulted to be “On” (in operation). NPS and other
compliance/safeguard features can not be field reconfigured, disabled or
removed. This Amplifier is not user programmable, does not need fine
tuning or adjustment.
In 2001 SmoothTalker produced the first digital mobile Mobile Network signal
Amplifier in North America with FCC and Industry Canada approval.
We continue to lead with the most powerful and intelligent Amplifiers
in the world. Our dynamic adaptive proprietary algorithms make
them totally network friendly. We call it STEALTH TECH technology.
