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.

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.

Installation & Assembly
Applications
This Direct Connect M2M Booster is designed to be placed between the cellular
device and it’s outside antenna.
Make all connections as in Fig. 1 and see Applications in Fig.2 & Fig. 3
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.

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 will only occur if you were to connect the inside antenna port
to outside antenna port. This is not normal and not recommended.
When the booster is o it will be indicated as follows:
When inside and outside antenna ports are connected together the Green LED
will fast ash and the Orange LED will turn o indicating that the booster is
o due to loop oscillation.

What do the LED ashes mean?
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. This will not occur in this type of direct connect Booster unless you mistakenly
connected the inside antenna port to the outside antenna port.
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.
