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 ashing (Per the chart on Pg. 7) 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 o it will be indicated as follows:
When inside and outside antennas are extremely close together the Green LED
will fast ash and the Orange LED will turn o indicating that the booster is o due
to loop oscillation.

Understanding the LED Indicators LED Lights Explanation and Troubleshooting
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 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 ashing
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 ashing Orange will automatically stop ashing which
indicates that the booster is no longer attenuated. As you approach another
nearby cell tower the Orange may begin ashing again and will stop ashing
as you get farther away. This is the normal operating process.

For example: three ashes 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 eld recongured, disabled or removed. This booster is not user programmable,
does not need ne tuning or adjustment.
In 2001 SmoothTalker produced the rst 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)
