QUICK INSTALL GUIDE
This quick install guide is intended for professional installers that
are generally familiar with the installation of cellular signal booster
systems that include bi-directional amplifiers, indoor and outdoor
antennas, signal splitters and coaxial cable. Additional details can
be found in the user guide
This amplifier has a very intelligent Automatic Gain Control System
(ALC and ISO) to adjust its uplink and downlink gain in each band to
prevent self-oscillations, optimize gain to prevent overload from
nearby high-power towers and to make installation virtually ‘plug and
play’.

It provides an overview of the amplifier, its features and information
about the controls and displays.
Main Elements and Typical Installation
Figure 1. shows the main elements of the amplifier that includes the
LCD panel, manual gain controls, indicator LEDs and the
OUTDOOR and INDOOR antenna ports which are type-N female
connectors. Figure 3 shows a typical system setup. Please use this
diagram as a general guide
LCD Display
When the amplifier is first powered on the LCD panel display will
turn on for 5 minutes. It is shown in Figure 2. If it is not ON press
the SET button momentarily.

Bands Covered: LTE 700, Cell 800, PCS 1900, AWS 2100
Power: Input AC (100-240 VAC), Output DC (12Vdc, 7 amps)
Installation Overview
1. Select a location with the strongest signal on the roof of the
building to install the Outdoor Antenna. Make sure the antenna
is pointed directly at the desired cellular tower and there are no
obstructions that could block the signal. You should also
consider attaching a grounded lightning protector between the
outdoor antenna and the Signal booster.
2 Select a location to install the Signal Booster that is in a
secure indoor location near a grounded AC power source and
well ventilated away from excessive heat, moisture, and direct
sunlight.
3 Select a location(s) for the Indoor Antenna(s), being sure to
take isolation distance requirements into account. In general,
long narrow spaces will benefit most from directional panel
antennas while more square spaces will benefit more from
omnidirectional dome antennas.
4 Proper antenna distance is essential to prevent signal
oscillation (feedback) that can interfere with the cellular tower
and as a precaution the amplifier will shut off in the affected
band. Distance is measured in a straight line from the outdoor
antenna to the closest indoor antenna. The closest allowable
distance depends on several factors such as booster gain
level, cable and splitter loss and building wall materials.
Typical minimum distances are shown below:
Amplifier Gain Min. Distance
50dB 50’
55dB 60’
60dB 70’
65dB 80’
70dB 100’
75dB 100’~120’
80dB 120’~180’
NOTE: Vertical distance is more important than horizontal
distance. If you are unable to obtain the required distance
horizontally, try raising the outdoor antenna to a higher level.
5. Route the coax cable from the Outside Antenna to the Signal
Booster and attach it to the connector labeled “Outdoor.”
Connect another coax cable to the connector labeled “Indoor”
and route it to the Indoor Antenna.
NOTE: Be careful not to bend the center pins on the connectors
when securing connections.
6. Once you have ensured all connections are tight, plug the
power supply into the Signal Booster input marked “POWER”
and then into an AC surge protector power strip with a
minimum 1000 Joule rating.
7. If the booster is working and adjusted correctly, the LEDs on
the front panel will be green and the LCD panel will show the
downlink power level (in dBm units). The Automatic Level
Control (ALC) will try to adjust the downlink output power to
the maximum level consistent with the constraints of your
installation and the signal level that is received from the local
tower.
If you have made the most appropriate installation per the
above procedures, but the Signal Booster’s ISO or ALC icons
are flashing on the LCD panel (especially if the installation
location is close to the cellular tower) you may also try
reducing the booster gain as described in Manual Gain
Control Operation Chapter of User’s manual.
A. Press the “SET” button for more than 3 seconds. It will go into
the “Manual Gain Setting Mode” (MGC) and make one of the
gain values start to blink.
B. Press the “SET” button shortly, and the LCD will switch to the
next gain value and it will start to blink. (uplink or downlink gain
for a different band).
C. Press “INC+” button once shortly and the gain will increase by
1dB, Press “DEC-” button once shortly and the gain value will
be reduced by 1dB.
D. Press the “SET” button for 3 seconds, and the LCD will return
to the fixed display mode and store the gain values
Note: Reduce the downlink gain first to achieve the desired
downlink power level (until the ISO and ALC icons on the LCD
display are not flashing) then reduce the uplink gain 5~8dB
more than downlink gain. For example, when the Downlink
gain is 70dB you may reduce the UL gain to 62dB.
