American Booster Clear Call has been designed to improve and extend cellular coverage inside
the buildings. Clear Call amplifies signals from the nearest base station and re-transmits them at
higher power level. Clear Call provides service at 700MHz LTE, 850MHz Cellular, 1900MHz PCS
and 2100MHz AWS frequencies without any additional setup or configuration.

Splitter and several internal antennas may be required in some spaces where signal improvement
is required for large houses or buildings. For example, in spaces where signal improvement is
required, the signal from Clear Call can be divided into two or more signals using splitter (sold
separately) and connected to an internal antenna (sold separately). These optional components
can amplify the signal into the required space.

In case of abnormal operation, technician should diagnose abnormality via remote access or
directly connecting to repeater using Ethernet cable. If technician is required to conduct repairs
due to major alarm, repeater should first be powered off, and then technician should prepare the
proper measurement equipment before trying to fix the problem. In most cases of major repairs,
GST will simply replace the unit and conduct repairs at the appropriate facility.
Simple Troubleshooting Method
1) Check LED status at rear of module
- Green LED on: Normal operation with maximum allowable gain.
- Red LED on: Shutdown by oscillation condition or over output.
2) Check external and internal connectors to ensure that all connections are tightly secure.
3) If user thinks there is a serious problem, call after sales team for over-the-phone technical
support. 913-469-6699.

ALC (Auto Level Control)
ALC maintains limit of the output power in order to protect bad influence to the Base Station.
AGC (Auto Gain Control)
The Signal Booster checks isolation between inside and outside antennas once a day.
AGC sets up downlink and uplink gain value automatically depending on the input power level.
ASD (Auto Shutdown)
There are two cases when ASD works.
1) Outside antenna and Inside antenna are not isolated enough from each other.
So in order to protect the Signal Booster from damage, it will automatically shutdown at this
frequency.
2) Uplink Signal coming from the outside antenna to Base Station is too strong and may cause
troubles to carriers network, so the Signal Booster will shutdown at this frequency.
