1. - MANUAL
Thank you for buying a repeater at our Shop. We sell high-quality, interference-free and energy-
efficient equipment with CE markings. For quick and easy installation of your device, you can of
course rely on the service of GSM Repeater Shop.
You should be able to get coverage pretty much anywhere. Sometimes, though, it is hard to get a
signal, due to newly constructed buildings with excellent insulation. Buildings made out of steel
and/or concrete often have the worst reception. The signal may be relatively weak in rural areas, due
to the limited number of transmission towers. We are able to offer appropriate solutions in nearly all
situations.
IMPORTANT!
A repeater retransmits and boosts the call signal (2G) and/or the data signal (3G/4G). Because
transmissions are sent on the frequencies of your provider, you will need your provider’s permission.
As the buyer/user, you are responsible for requesting the permit to put the repeater into service and
use it.
2. - THE 6 GOLDEN RULES FOR A SUCCESFUL INSTALLATION
1. Place the outdoor antenna as high as possible on the outside of your building! Preferably on
a roof, chimney or pole.
2. Place your antenna on the correct side of your building. Check section 2.2 of the manual,
‘WHERE IS MY BASE STATION LOCATED?’, for more information.
3. Make sure the outdoor antenna is located far enough away from the indoor antenna.
4. Never switch on the repeater if it is not yet connected to any antennas. This can damage the
repeater and is not covered by the warranty.
5. Do not place an indoor antenna in an area where you already have good reception.
6. Only use the special coaxial repeater cables that have the specifications given on our
website.

3.2 - WHERE IS MY BASE STATION LOCATED?
There are a number of ways to determine the best place for the outdoor antenna. Below you will find
several free apps that you can download which will measure the quality of the incoming signal in
different locations on and around the building.
Make sure that the outdoor antenna is placed where the incoming signal was measured to be the
strongest. The general rule of thumb is: the higher the antenna, the better.
For Android Smartphone
1. Download the app netmonitor
Measure the signal type and strength and see to which BTS you are connected.
IMPORTANT: Use a phone with the sim card of the provider you want to amplify.
2. More basic: go tot he settings of your phone (the path will change from phone to phone) and
find the menue or submenue “network” or “signal strength” to find a value in -xxx dB.
Here under you find the explanation about the values.
For IPhone (There can be updates to the software availble) Go to your dialpad (as if you want to call
somebody) and dial the code *3001#12345#* and press call.
1. You get into the field test mode.
Every IPhone, depending on the software and model, looks a bit difrent from here.
You should look for LTE (or UMTS or GSM) Serving cell info and a value that is listed under
rsrp0 or rsrp and displays a value in –xx dB,
You might also have a menue with a splitt between LTE, UMTS, GSM division on the first
screen an look for the value of rsrp0 in –xx dB on following screen.
The values keep changing, because the signal is fluctuating whenever you change postion.
Keep repeating your measurement until you have determined the best location on or around the
building.
-51 ~ -76 dBm = maximum ~ good reception = 100 ~ 55 %
-76 ~ - 87 dBm = good ~ decent = 55 ~ 39 %
-87 ~ - 98 dBm = decent ~ average reception = 39 ~ 23 %
-98 ~ -107 dBm = average ~ bad reception = 23 ~ 9 %
-107 ~ - 121 dBm = bad ~ very bad reception = 9% ~ 0 %
To figure out which provider has the best signal in your neighbourhood, you can check the website
http://opensignal.com. You can also see where the nearest transmission tower of your provider is
located. Fill in your country and zipcode in the ‘Search for your address or zipcode’. Then click on
‘Masts’. You can see where your transmission tower is located. To our knowledge, this is the best
method. Sadly, the website does not offer 100% coverage and no rights may be derived from it.

3.3 -PLACING AND AIMING THE OUTDOOR ANTENNA AND INSTALLING THE REPEATER
PLACE YOUR ANTENNA AS HIGH UP AS POSSIBLE
This part of the installation process is very important. If the reception isn’t good outdoors, it will not
be good indoors. This is also the case if you live in a rural, wooded area. Trees absorb the GSM signal,
which reduces the quality considerably. Placing the antenna high up does not make installing it any
easier, but will certainly improve the results. If the signal strength outside your front door is less than
4-5 bars, the signal is actually average. An outdoor antenna that is high up and aimed in the right
direction is of vital importance in getting the repeater to work efficiently. Find a suitable location for
the outdoor antenna and aim it towards the proper transmission tower.
NOTE: The following is only when using a Yagi directional antenna.
-Pointing it in the direction of the transmission tower is important. The arrow shape will show
the correct horizontal position. The antenna has to be placed ‘lying down’ (see pictures
below). This is the case with all Yagi antennas.
*with the condensation drain hole at the bottom
KEEP ENOUGH DISTANCE & MASS (walls and floors) BETWEEN THE INDOOR AND OUTDOOR
ANTENNAS.
If there is not enough distance and/or mass between the indoor and outdoor antennas, the antennas
go into a feedback loop, which causes interference. This causes problems for the GSM transmission
tower. The indicator lights will go red. Should you be unable to create enough distance or mass
between the antennas, use a lead blocker or chicken wire to shield the antenna and to prevent
feedback.

© Copyright reserved V.7.0 EN 13
3.4 – CONNECTION
1. Screw the whip indoor antenna into the ‘Output’ connection point on the repeater.
2. Run the cable from the outdoor antenna to the desired location of the repeater. Make
sure that you have enough distance (at least 5 to 10 metres). There should be at least
one brick/steel wall/floor in between the indoor and outdoor antenna. Screw the
outdoor antenna’s connector into the ‘Input’ connection point on the repeater.
3. When both antennas are connected, connect the adapter and plug it into the power
point. All the indicators should be green. If they are, you will have a good GSM signal in
the immediate vicinity of the indoor antenna!
Note: Performing a test is advised. Connect the equipment provisionally so that you can see if the signal is
sufficiently amplified. With sufficient signal you can install the equipment permanently. Make sure that the
equipment remains undamaged and scratch free as long as it is not installed definitively.
Place the indoor whip antenna on “Indoor”or “Output”or ”MS”
Connect the adapter
to the powersupply
Connect the Outdoor Antenna
with the repeater. Use “Outdoor” or
“Input” or “BTS” and the coaxial cable

3.5 – CALIBRATING THE EQUIPMENT
3.5.1 - For the Model 1 repeaters:
If an indicator light is green, the signal is at its best. You do not have to do anything.
If an indicator lights is orange, you have a little too much signal. Please check under * what to do.
If an indicator light is red and after a few seconds turns off, you need to adjust the setup.
* Create more mass or distance between the indoor and outdoor antenna. this means:
- Place the indoor antenna further away from the outdoor antenna
- Place an extra wall between indoor and outdoor antenna
- Place the indoor and outdoor antenna as far away from windows as possible
- Place a piece of lead or steel between the indoor and outdoor antenna
- Order extra coaxial cable to move the indoor antenna further away
- Place the outdoor antenna higher on the building
If this do not make the indicator lights green you can adjust the white dip switches. The repeater
works at maximum power. If you move the dipswitches to “on” and the incoming and outgoing
signal will be reduced. This is a “trial and error method”.
IMPORTANT
1. Never leave your GSM repeater switched on with a red light for a long time.
2. First mount your antennas before turning on the repeater.
For the single band repeaters with 4 dipswitches
Flip up dip switches 1 and 3. This causes a 50% decrease in the in- and output.
For the repeaters with 10 dipswitches per band
When you have 2 green leds per band, the repeater should work. No more actions needed. If you
have a red or no light: Flip up dipswitch number 1 and 6. This causes a slight decrease in the output.
If the indicator lights are still not green, also flip up dip switches 2 and 7. Then flip up switches 3 and
8. Then flip up 4 and 9. Then flip up 5 and 10. If all lights are still red, please take pictures of this side
of your repeater, the indoor antenna and outdoor antenna and Whatsapp them to [phone]
63 along with your order number.
When the leds turn green, start to flip down number 1 and 6. If the indicator lights are still green,
also flip down dip switches 2 and 7. Then flip down switches 3 and 8. Then flip down 4 and 9. At the
end as many possible switches should be down and the light should be green.
EXAMPLE OF DIP SWITCHES
If your repeater is not working properly after these steps, please contact us. We will be happy to help you!

3.5.2 - For the Model 2 repeaters:
1. After switching on the repeater, "Power" and "ISO" (see display) must light up green. If "Power" is
not lit green, the repeater is not receiving power.
When “ISO” lights up in red or orange, the indoor and outdoor antenna must be placed farther away
from each other or more mass (walls, cabinets - everything with weight) must be created between
the two antennas. Both antennas should also be placed as far away as possible from windows to
prevent interference.
2. The repeater is set to “Smart” by default. This means that the repeater optimally adjusts itself. If
you still want to adjust the repeater yourself, you can do this by pressing the "M button". If the
"ISO", "Smart" and "Power" lights are green and the repeater is not working optimally, it is advisable
to press the "M" button and to switch off the smart function. If "ISO" turns red, go back to step 1.
3. Your repeater amplifies two frequencies. You can switch between these bands with the “SEL
button”. It concerns the 900 or 1800 MHz band.
4. The display also shows the UL value (Uplink - what you send to the mast) and the DL value
(Downlink - everything you receive from the mast).
5. With the “M button” you can manually reduce / adjust the gain so that your repeater functions
optimally. The "ISO" and AGC (Auto Gain Control) then turn green.
6. When the smart function is switched on, you will see "AUTO" in the display. When the smart
function is switched off, the display shows ‘MANU’. Our advice is usually to enable the smart
function.
If after all efforts you still don't have a functioning GSM repeater, please contact us. We are happy to
help you further!

© Copyright reserved V.7.0 EN 16
3.5.3 - For the Model 3 repeaters:
We advise you to always to use the smart function. Using the "Smart Function", the GSM repeater
itself ensures the optimal settings. This is the starting position of the repeater. If not, press to
activate this function.
If the "ALARM" LED light is green, the repeater is working. Note: You can make fine calls and the
installation is successful. If you have 1 or 2 bars on your phone, the incoming signal is not optimal. Go
to: “How do I optimize my repeater”
When the "ALARM" LED flashes green or orange. The repeater has (slight) oscillation. It enters AGC
(Automatic Gain Control) mode and reduces the power of the repeater. Please go to: “How do I
optimize my repeater” (see below).
If the "ALARM" LED flashes red, the repeater has heavy oscillation and switches itself off after 5
seconds. Go to: "How do I optimize my repeater".
If the "POWER" LED is not lit, the adapter is defective.
If the "ISO" LED light is green, the repeater works fine.
If the "ISO" LED flashes green quickly or slowly, go to "How do I optimize my repeater".
"How do I optimize my repeater"
-The indoor and outdoor antenna are as far apart as possible.
-Place as much mass (walls, floors, etc.) between the two antennas as possible.
-Place both the indoor and outdoor antenna away from windows.
-Make sure that the outdoor antenna is placed outside towards the transmission tower, as
high as possible.
Otherwise, the repeater will not set itself properly and will lose a lot of power.
If the incoming signal (RSSI) is too strong, the Smart Function will not work (properly). For the
repeater to function properly, a signal is required between -60 and -90 dBm. You will find this value
(s) on the left side of the display. If the signal is better than -60 (lower, for example -40), it is
advisable to purchase a signal attenuator or to move your Outdoor antenna away from the BTS. This
decreases the incoming signal. If the value is less than -90 (higher, for example -98), you need a
directional antenna or place the outdoor antenna in a more favorable location.
If your repeater amplifies multiple bands, the top value on the display is the lowest frequency. And
the bottom the highest frequency.
If your repeater is still not working properly after all these steps, please contact us. We will be happy
to help you!

© Copyright reserved V.7.0 EN 17
3.5.4 - For the Model 4 repeaters:
The repeater has two modes: MANUAL and AUTO. In MANUAL mode, users can set the gain
manually. In AUTO mode, the gain is controlled automatically. We recommend choosing the
automatic setting. This is also the starting position.
In section 2, using the UP and DOWN buttons, you can move the cursor to this section. Pressing the
ENTER button changes the working mode.
In section 3 you can choose the band. 900 (calling) or 2100 (Internet) MHz.
Section 4 shows the incoming signal (RSSI). A properly working repeater needs a signal between -60
and -90dBm. If the signal is better than -60, it is advisable to purchase a signal attenuator or to move
your Outdoor antenna away frim the BTS. This decreases the incoming signal. If the value is below -
90, you need a directional antenna or place the outdoor antenna in a more convenient location.
Section 5 shows the actual gain of the repeater. This can vary between -10 and +10 dBm.
In section 1 you can manually set the repeater. We do not advise this. If you still want to do this, then
set the repeater to MANUAL mode.
LED indicator
Power green: Repeater is switched on Power off: Repeater is switched off
Alarm green: Repeater is working properly Alarm red: Repeater has a problem
If a repeater gives a red Alarm light or the signal is poorly amplified, make sure that:
- The indoor and outdoor antenna are as far apart as possible.
- Place as much as possible mass (walls, floors, etc.) between the two antennas.
- Place both the indoor and outdoor antenna away from windows.
- Make sure that the outdoor antenna is placed outside towards the transmission tower, as high as
possible.
Otherwise, the repeater will not set itself properly and will lose a lot of power.

© Copyright reserved V.7.0 EN 18
3.5.5 - For the Model 5 repeaters:
The repeater model 5 is standard equipped with AGC (Automatic Gain Control). This allows the
repeater to set itself as optimally as possible. Sometimes this is not possible, then
- the “ISO” lamp flashes ”, press the“ SET ”button. You can then see which bands are causing the
problem.
You can solve the problem by:
- Take the indoor and outdoor antenna as far apart as possible.
- Place as much as possible mass (walls, floors, etc.) between the two antennas.
- Place both indoor and outdoor antenna away from windows.
- Make sure that the outdoor antenna is placed outside towards the transmission tower, as high as
possible.
Otherwise, the repeater will not set itself properly and will lose a lot of power.
- If the ALARM light flashes, press the “SET” button. You can then see which tires are causing the
problem. The display shows ALC.
You can solve the problem by:
- Take the indoor and outdoor antenna as far apart as possible.
- Place as much as possible mass (walls, floors, etc.) between the two antennas.
- Place both the indoor and outdoor antenna away from windows.
- Make sure the outdoor antenna is placed outside, not towards the transmission tower.
- Order a signal attenuator on our website.
Otherwise, the repeater will not set itself properly and will lose a lot of power.
If the display is set to “OFF”, the repeater suffers from severe self-oscillation. Follow the tips
described under “ISO” light will flash ”then…

© Copyright reserved V.7.0 EN 19
3.5.6 - For the Model 6 repeaters:
1. Shows the Up and Down Link of the frequency
2. Shows the maximum gain of Up and DownLink.
3. Smart function. The repeater sets the strength automatically to prevent the alarm.
4. Detection of antenna isolation. When the indoor and outdoor antenna are too close together, the
repeater automatically detects this oscillation.
5. ALC alarm indicator.
6. Five bars of the maximum possible strength of the output signal. Each signal bar represents 5 dB.
7. Enter for selection or confirm the settings.
8. MGC - allows you to manually set the repeater. Is not advised by us.
9. Switching the Smart function on and off.
Users should ensure that the ISO and ALC lights always remain green for optimal system
performance. You can solve the problem by:
a. Separate the indoor and outdoor antenna as far as possible.
b. Place as much ground (walls, floors, etc.) between the two antennas as possible.
c. Place both the indoor and outdoor antenna away from windows.
d. Make sure the outdoor antenna is placed outdoors away from the transmission tower.
e. Order a signal attenuator on our website.
If both lights are green, but you can only make a good call if you are close to the repeater, the
repeater does not set itself properly and loses a lot of power. Then go to points a. to c.

3.5.7 - For the Model 7 repeaters:
A B
A = connection for coaxial cable to outdoor antenna
B = connection for the indoor antenna
This repeater model has an Uplink Standby. When no device is in use, the repeater
automatically decreases its power.
I.S.O. - Self-oscillation elimination and Auto Shut Off
When the insulation between outdoor and indoor antenna is insufficient, the text I.S.O.
appear on the display. The repeater will automatically decrease the gain to function
normally.
When severe self-oscillation occurs, the signal output is automatically turned off (Auto Shut
Off) to prevent self-oscillation and prevent interference. I.S.O. visible on the display and the
run light turns orange or red.
If there is I.S.O. is visible on the display, make sure that:
- The indoor and outdoor antenna are as far apart as possible.
- Place as much mass (walls, floors, etc.) between the two antennas as possible.
- Place both the indoor and outdoor antenna away from windows.
- Make sure that the outdoor antenna is placed outside towards the transmission tower, as
high as possible.
