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.

Boosts the outside signal into your vehicle
and the cell phone signal back to the tower.

To comply with FCC rules, this booster must only be operated with cables, antennas
and coupling devices that have been approved for use with this equipment.
NOTE: It is normal for the booster to be quite warm while the phone is in use state.

Installation
Installation
1) Connect the outside antenna to the side of the booster
marked as “outside antenna”
Connect the inside antenna to the side of the booster
marked as “inside antenna”
2) 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 booster as shown in Fig.1 below.
Important: Use only the power supply included with the booster. Connecting any
other power supply at any time will result in damage to the booster and will void
the warranty. Do not turn on the power switch until ALL cables have been
screwed or plugged into the booster or you can cause damage to the booster.

Understanding the lights
The “LEDS” on the face of the booster indicate operating gain state.
In any given frequency band there is a Green and Orange LED which indicate the
gain status of the band. When both of these LEDS are “SOLID ON” it means that the
booster is operating normally and with full gain (No attenuation) in that band.
If the booster has reduced its gain, one or both of the LEDS will indicate
by ashing. (Per the chart on pg. 4)
Any reduction of gain will be due to either:
A) High outside signal level (close to tower)
B) Loop Oscillation due to the inside antenna (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.

Orange Slow Flashing & Green Solid ON = RX High Power Att
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 indicates RX (outside signal strength) status. 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
boooster is no longer attenuated. As you appproch 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.
Each ash indicates 3dB of gain reduction also known as gain attenuation.
For example: three ashes equals 9dB of attenuation.
