Understanding the LED Indicators
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 RX outside signal level (close to cell tower)
B) Loop Oscillation, caused when the inside antenna is located too close to the
outside antenna.
Band 20 800MHz
Band 8 900MHz
Band 3 1800MHz
Band 1 2100MHz

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 indicates RX (outside signal) status.
There are 5 Orange LED lights: 700 Mhz Lower, 700 Mhz Upper, 850 Mhz,
1700/2100 Mhz,1900 Mhz ext. 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.
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.

To comply with European rules, this Amplifier must only be operated with cables, antennas
and coupling devices that have been approved for use with this equipment.
NOTE:
Only one of the outside antennas is included in this kit. 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. All parts shown are not included in all kits.
