Operation
This manual covers operation, installation and troubleshooting procedures for
the bi-directional amplifier Model: F27-5S.
The F27-5S amplifier is designed to help wireless device users amplify weak
signals of all the major carriers in the 2G, 3G and 4G bands. This bi-directional
amplifier is used to boost uplink signals from the phone to the local cell site
tower and simultaneously amplifying downlink signals transmitted from the
tower to the phone. An antenna located outdoors (donor antenna) receives
signals from the cell site tower, transmits them to the amplifier and then
rebroadcasts them on antennas located indoors to the wireless device. The
indoor antennas also received signals transmitted from the phone that are
boosted in the amplifier and sent to the tower via the outdoor donor antenna.

F27-5S Booster Power Supply 12V/7A
* Outdoor and indoor antennas and cables are required for installation
(purchased separately).
The F27-5S industrial amplifier requires outside and inside antennas connected
with appropriate coaxial cables and a splitter network. The F27-5S can typically
power 8-15 indoor antennas but the exact number of antennas, length of cable
or other accessories needed can vary according to the size and construction
materials used in the building, outdoor signal strength and layout of the structure.

LCD Features
After the booster is powered on, uplink (UL) and downlink(DL) gain and DL
output power are displayed. “Band”–Shows the working frequency. Below is a
list of the frequencies displayed corresponding to the Band display shown on
the screen.
“UL (dB)”“DL (dB)”– Gain Indication.
The displayed value shows real-time uplink and downlink gain. These values
will change slightly as the ALC or ISO makes changes to the gain to optimize
coverage.

“Power dBm ”–Power Indication.
The displayed value shows real-time downlink power that the amplifier is
delivering to the indoor antenna port. When the amplifier DL output power is
lower than -10dBm, the value will display ”---”.
“ISO” –Isolation Alarm Indication.
When the system does not have enough isolation between the outdoor and
indoor antennas, the “ISO” indicators will be flashing showing that the ISO is
lowering the gain in some bands to keep the system from oscillating. Press
the ”SET”key and the LCD screen will display ”ISO” showing the current band
or bands affected.
“ALC” Flashing.
When the amplifier is receiving too much DL power from the tower and the DL
amplifier output is close to saturating, the “ALC” indicators will flash showing that
the ALC has lowered the gain to prevent this overload condition. Press the ”SET”
button and the screen will show the band or bands affected.
”OFF”- Booster shut-off alarm indication.
In some rare situations the ALC or ISO will not be able to compensate for an
oscillation condition or a downlink overload. When this happens the amplifier
will shut off in the affected band and the LCD “OFF” indicator will flash.
Pressing the “SET” button will display which band or bands are affected.

Manual Gain Control Operation
There are 4 operation modes relative to the control buttons: a long press for
more than 3 seconds on the “SET”button, short press on the “SET”button, short
press on “DEC-”button and short press on “INC+”button.
When the LCD is in the fixed display mode, press the “SET”key for 3 seconds
and it will start up in the Gain Setting Mode.
Press the “SET”key shortly, and the LCD will switch to the next
value (uplink or downlink gain for a different band).
Press the “INC+” (or “DEC-”) key, and the value of the current g a i n
item will change to a higher (or lower) one.
Press the “SET”key for 3 seconds, and the LCD will return to the fixed
display mode. (For more details refer to Manual Gain Control (MGC)
below.
When the LCD is in the alarm display mode, press the “SET”key and the LCD
screen will display the alarm indication showing the affected band. Pressing the
“INC+” (or “DEC-“) key and the LCD will switch to help tips. If none of keys are
depressed within 30 seconds, the display will return to the fixed display mode.
If none of the control keys are depressed within 5 minutes, the LCD screen will
turn off. Pressing any key will return the display to the fixed mode.

Manual Gain Control (MGC)
Since the booster has a very good self-adaptive smart automatic level control
(ALC) and isolation gain processing (ISO) , most of the time manual
adjustments are not required to achieve good coverage. However, in some
cases where the ALC or ISO is working at a very high rate to adjust the gain
and the Alarm or ISO LED is flashing more than once a second a manual
adjustment might be desired.
When the LCD is in the fixed display mode, press the “SET” key for more than 3
seconds. It will go into the “Gain Setting Mode”and make one of the gain
values start to blink.
Press “SET”key 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).
Press “INC+”key once shortly and the gain will increase by 1dB, Press
“DEC-”once shortly and the gain value will be reduced by 1dB.
Press the “SET”key for 3 seconds, and the LCD will return to
the fixed display mode.
Note: When adjusting the gain manually, please ensure that the uplink gain
is equal to or not 5 dB less than the downlink gain setting. This avoids
interference with the local cell site tower network.
System Installation
Before You Install

Installation Overview
This amplifier has an LCD display and smart self-adaptive Automatic Level
Control (ALC) and Isolation gain processing (ISO) system. The LCD displays real
time working status and the ALC and ISO can automatically calculate and adjust
the booster gain to obtain its optimum performance. So it is very easy to install.
General installation steps:
1. Install the outdoor antenna on the roof to obtain the strongest downlink
signal from the local cell site towers.
2. Install the indoor antennas where you want to improve the signal level.
3. Mount the amplifier, connect the cables from the outdoor antenna and
indoor antenna at the designated ports, and connect the booster to the AC
supply (make sure all the cables are connected before applying power).

1.1 How to find the location with the strongest received signal
The booster’s main function is to improve a weak RF signal inside a house,
office or any other indoor area. The received outdoor downlink signal strength
directly affects the efficiency of the indoor coverage. That is why it is crucially
important to install the antenna at a good location and point it properly
towards a tower where signal reception is the strongest.
There are three methods that can be used to find the strongest downlink signal
from the local towers. One is to use the LCD display on the amplifier that shows the
downlink power output of the amplifier in each band, the other is to use a mobile
phone that shows the signal bars and the third is to use a commercially available
signal strength meter. We highly recommend that you use the LCD display on the
amplifier as this method is generally more accurate. However, in situations where
the desired carrier’s signal is much weaker than the other local signals, using a
signal level meter can be a more accurate method of homing in on the best signal
for an installation.
