LED Lights Explanation and Troubleshooting
The LED lights on the amplier face plate indicate the operating gain state of
the amplier.
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 amplier
is operating normally with full gain (No Automatic Gain Reduction)
When one or both of the LEDS are ashing (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 ash indicates 3dB of gain reduction also known as gain attenuation.
For example: three ashes equals 9dB of attenuation.
Green LED indicates loop oscillation status. When ashing 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 amplier is working at its max gain.
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 ashing 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 amplier 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.
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 eld recongured, disabled or
removed. This amplier is not user programmable, does not need ne
tuning or adjustment.
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 techsupport@smoothtalker.com and we will help
you determine your cell tower location and get you setup.

No Flashing = Full Gain
Each Flash = up to 3dB gain reduction
Each Flash = up to 3dB gain reduction

In 2001 SmoothTalker produced the rst digital mobile Mobile signal
amplier in North America with FCC and Industry Canada approval.
We continue to lead with the most powerful and intelligent ampliers
in the world. Our dynamic adaptive proprietary algorithms make
them totally network friendly. We call it STEALTH TECH technology.

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 amplier to be quite warm while the phone is in use state.
To comply Smoothtalker warranty, this amplier must only be operated with cables, antennas, and coupling
devices that have been approved for use with this equipment (Pg. 5).
