LED Lights Explanation and Troubleshooting
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 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.
Orange LED
There are 4 Orange LED lights: 800Mhz, 900Mhz, 1800Mhz,
2100Mhz. LED ON state indicates that the RX (Receive Signal) function of
the band is functioning normally.
LED OFF
(Green or Orange)
: indicates that the band is shut down. When flashing
it means reduction of gain also known as attenuation of gain. You cannot
prevent this condition. As you drive away from the nearby cell tower and get far
enough away the flashing Orange will automatically stop flashing which
indicates that the booster is no longer attenuated. As you approach another
nearby cell tower the Orange may begin flashing again and will stop flashing
as you get farther away. This is the normal operating process.

The “LEDS” on the face of the booster indicate operating gain state. In any given
frequency band. The Green and Orange LED which indicate the gain status i each
operating band. When both of these LEDS are “SOLID ON” it means that the booster
is operating normally and 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 RX outside signal level (close to cell tower)
B) Loop Oscillation, which is due to the inside antenna (either on holder or
Patch antenna) and the outside antennas are located too close together.
When the booster is off it will be indicated as follows:
When inside and outside antennas are extremely close together the Green LED
will fast flash and the Orange LED will turn off indicating that the booster is off due
to loop oscillation.

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
Fast Flashing = booster shutdown (pls troubleshoot)
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 booster is not user programmable,
does not need fine tuning or adjustment.
In 2001 SmoothTalker produced the first digital mobile cellular signal booster in
North America with FCC and ICAN approval. We continue to lead with the most
powerful and intelligent boosters in the world. Our dynamic adaptive proprietary
algorithms make them very 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 booster to be quite warm while the phone is in use state.
To comply Smoothtalker warranty, this booster must only be operated with cables, antennas, and coupling
devices that have been approved for use with this equipment (Pg. 5).
