Congratulations on the purchase of
your new Clear Voice Cell Repeater!
Safety First
For your safety and to prevent injury to the installer or the operator, it is essential
to read this manual carefully before your new unit is installed and operated.
_____________________________________________________________________
Through out this document this symbol indicates potential injury incase the operator
fails to follow the guideline or common sense during the installation of the repeater unit.
Personal safety
This unit is powered by small AC adaptor unit. Turn off the electricity supply if
you have to do any rewiring or making alterations to wall sockets.
The equipment should be used only for amplifying mobile (cellular) phone
signals and not for any other purpose.
Should the unit fail to operate, any repairs should be carried out by qualified
personnel ONLY.
The RF energy that the unit radiates is very small (max of 5mW) this level is
many times smaller than the RF power radiated by your mobile phone.

General Repeater Information
Introduction
Almost all of us have experienced a dropped call or
“
Service Not Available
”
messages on our cell phones. This phenomenon occurs because there is
inadequate signal strength from the cellular towers that provide network
coverage. You see the base station cellular towers along roadsides, on top
of communications towers, and installed on some buildings in urban areas.
Often transmission to and reception from a cellular tower is weak because
the tower is such a long way away from the mobile unit. Other times,
buildings block the cellular signal or make it patchy. Full coverage is quite
rare, and due to
“
poor reception
”
we experience interruption of conversations,
voice distortion and dropped calls.
The Clear Voice Cellular Repeater is the solution to this problem. Repeaters
not only amplify the weak received signal, but they also reduce the need for
high level of RF transmission from your cell-phone, reducing undesirable
radiation exposure and battery drainage. The Clear Voice Cellular Repeater
is ideal for areas such as offices, apartment blocks and homes where your
phone is ordinarily unable to get adequate reception. By boosting the signal,
this device enhances the signal from your handset, ensuring a reduction in
noise and call drops, and so better quality of service.
So how does it work?
Look at the image on the next page to understand the setup of the Clear
Voice Cellular Repeater kit. The repeater is made up of two main parts: the
directional panel antenna and the Clear Voice amplifier unit. The directional
panel antenna is aligned with the closest cell phone tower, and collects the
cellular signal. This signal is then sent via a 30-foot cable to the Clear Voice
amplifier unit. The amplifier unit boosts the signal, and then retransmits it
about your home or office using a monopole broadcast antenna.

Installing your Clear Voice Repeater
Site Selection
The first thing you need to do before installing your Clear Voice Repeater is to
find out where you want to install the repeater. Look at the diagram below for
an idea of how the Cellular Repeater works:
1. The cellular signal is broadcast to/from the cellular tower.
2. The directional panel antenna collects the signal from the cellular tower.
3. The Clear Voice Repeater amplifies the signal and re-broadcasts it
about your home/office.
4. Ideally, the Clear Voice Amplifier Unit and the monopole broadcast
Clear Voice Repeater Installation and Operation manual

antenna (3 in image above) should be placed central to your
home/office in order to maximize coverage. The directional panel
antenna (2 in image above) should be outside your home/office, facing
towards the closest cellular tower and with as few obstructions
(buildings, cars, trees etc) directly in front of it as possible – an elevated
position often helps this. More information on the placing of the
directional antenna is provided below.
Step 1 – Locating the Cellular Signal
The best way to find the best cellular signal around your
home/office is simply to walk around with your cell phone
on. You should use a cell phone on the network/band
whose signal you are trying to improve. The “Signal
Strength” meter on your cell phone will tell you where the
signal is strongest. Note: The Cell Phone “Signal
Strength” meter takes up to 30 seconds to update as
you move from location to location, so make sure to
take a nice long pause in every location you test. The
place you choose should either be outside, or in the very
least by a window. It should also be within 30 feet of
where you want to rebroadcast the cellular signal (this is the length of the
provided cable).
Step 2 – Set up the Cellular Repeater
Once you have established what part of your home has the best signal, you
will need to set up the Clear Voice Repeater.
1. Place the panel antenna in the place with the best signal and connect it
to the 30 foot cable.
2. Connect the other end of the cable to the connector on the bottom side
of the Clear Voice Amplifier Unit (marked “BTS”).
Clear Voice Repeater Installation and Operation manual

3. Finally, connect the monopole broadcast antenna to the connector on
top of the Clear Voice repeater (marked “SERVICE”).
4. Move the Clear Voice amplifier unit inside to where you want the signal
to be rebroadcast. Try to make sure that the directional panel antenna
and Clear Voice amplifier unit are as far away from each other as
possible, and separated by a wall if at all possible.
Point 4 above is very important because it provides isolation between the
directional panel antenna and the monopole broadcast antenna. The two
antennas need to be isolated from one another in order to prevent
feedback/oscillation (this occurs when the directional input antenna picks up
the signal broadcast by the broadcast antenna). In order to prevent
feedback/oscillation, the directional panel antenna and the monopole antenna
should be distanced from each other, and the directional panel antenna
should always be facing away from the monopole broadcast antenna. It is not
vital to have a wall between the panel antenna and the amplifier unit, but if
possible, it can help reduce the changes of oscillation/feedback occurring.
5. Make sure that the panel antenna is facing in a direction AWAY from the
Clear Voice amplifier unit.
6. Plug the DC adapter provided with the Clear Voice package into an
electrical socket, and connect the other end to the “DC in” plug on the
bottom of the amplifier unit.
7. The unit’s power “on” light should turn green, signaling that the unit is
operating.
STEP 3 - Aligning the Directional Antenna
Now go back to the directional panel antenna. As you turn the panel antenna,
the indicator lights will show the strength of the signal from the direction it is
facing. Have someone else stand by the indicator lights, and tell you which
direction provides the strongest signal (highest light level). Make sure never
to turn the directional antenna so that it is facing the direction of the
Clear Voice Repeater Installation and Operation manual
Telecom Technologies (USA) LLC
www.cellboosterstore.com
Clear Voice amplifier unit (see image below). Depending on the signal
quality in your area, you will be able to get a low, medium, or high strength
signal. In order for the Clear Voice repeater to work properly, you will need to
find at least a medium (5-6 lights on) signal – the “low” signal level is just
background signal noise and will not improve your cellular signal.
IF THE “FAIL” LIGHT IS CONSTANTLY LIGHTED:
This means that the input signal strength is too strong, causing what is known
as “signal saturation” – this reduces to effectiveness of the repeater unit. You
should change the direction of the antenna to a direction from which the
signal is weaker, such that the “FAIL” light is not constantly on.
IF THE “ALM” LIGHT TURNS ON:
This “alarm” light signals oscillation due to signal feedback. When the alarm

light is on, the unit is no longer operation – it will automatically reset after one
minute or you can reset the unit manually by disconnecting and reconnecting
the power cable. In order to prevent the alarm light from turning on, you need
to insure the isolation of the directional antenna from the monopole broadcast
antenna. To do this, make sure that the directional antenna is facing away
from the repeater unit and is sufficiently far away. Also, you can improve
isolation by installing the repeater with a wall between the directional antenna
and the repeater unit. See the “Step 2” of the installation procedure above for
more information.

STEP 4 - Finalizing the Cellular Repeater Installation
Once you have found the direction with the best signal, you will need to fix
the panel antenna in that direction. The panel antenna comes with fixtures
that allow you to fix the antenna in any direction. Find a suitable place and
install the fixture to a wall or window frame with the four provided screws. The
fixture’s direction is adjustable both horizontally and vertically. Once you have
chosen the direction for the fixture, it can be fixed in that direction by
tightening the screw that runs horizontally through the fixture. Once the
directional and position of the fixture have been fixed, the directional panel
antenna can be connected by sliding the directional panel antenna from
above onto the fixture. You will hear a click once the directional panel
antenna has locked into place.

Finalize the position of the Clear Voice amplifier unit by making sure that it is
in an unobstructed place (to allow maximum cell phone signal about your
home/office). You can also hang the Clear Voice repeater from a wall if you
wish (a fixture is provided for this on the back of the unit). In general the unit
should be placed approximately at head-height (i.e. 6 feet from the floor). The
monopole antenna should always be fixed vertically.
Now you’re ready to enjoy improved cell phone reception. Simply pick up
your phone and make a call!

Common Customer Questions
Is it possible to purchase and use an extension cable?
Extension cables should only be used if the signal strength outside your
home/office (or wherever the directional panel antenna is installed) is quite
strong (3 or more bars on your cell phone without the repeater installed). If
the signal strength is relatively weak, the use of an extension cable will
decrease the signal further, and thereby decrease the coverage area of the
repeater system.
Visit our website or call us for information about purchasing an extension
cable for your repeater. Using third-party cables with our repeaters will void
the product warranty.
Will the repeater improve signal on more than one level of my home or
office?
Due to the nature of the omni directional antenna used with our repeater (and
with almost all other commercial repeaters) the improvement in signal
coverage is largely limited to the level on which the repeater is installed
(though some improvement will be seen on adjacent levels). For this reason,
you should install the Clear Voice amplifier unit on the same level where you
will be using your cell phone.
Is the repeater system waterproof? Can it be installed outside?
The directional panel antenna is waterproof, and can be installed outside.
However the Clear Voice amplifier unit is not waterproof and must be installed
indoors in a controlled temperature environment (maximum ambient
temperature for correct operation is 40°C or 104°F) .
Does the repeater support multiple network carriers?
The repeater will amplify the signal on all carriers operating on the frequency
band of the repeater in your area (either 800 or 1900 MHz, depending on the
model you have purchased).
