Congratulations on purchasing a Clear Voice 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. 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.

Introduction Almost all of us have experienced dropped calls or “Service Not Available” messages on our cell phones. This occurs because there is inadequate signal strength from the cell towers that provide network coverage. You can see the cellular towers along roadsides, on top of communications towers, and installed on buildings. There are many causes of weak cellular signal: • There may simply be no cell tower within range.
What to expect After installing your cell phone repeater, you should no longer experience dropped calls or poor call quality. However, there are a number of things to consider: • You will experience the largest improvement in signal strength when you are near the repeater unit. With the repeater properly installed, your phone should display full bars when you are near the repeater’s antenna. • Our repeaters offer a coverage area of up to 2,500 square feet.

Repeater Terminology Here are a few terms that you’ll need to be familiar with in order to use this instruction manual. Please read carefully. Directional Outdoor Antenna This is the antenna that is used to collect and route signal to the cell phone tower. Monopole Antenna This smaller antenna is attached to the top of the Clear Voice amplifier and rebroadcasts the signal inside your home or office. Other types of rebroadcast antennas are also available and can offer a better in-door coverage.
Installation Installing the repeater is a simple process, but please make sure to read each step thoroughly before starting. The performance of your repeater kit is very sensitive to the installation.
Step 1: Locating the Optimum Position Position for the Outdoor Antenna The first thing you need to do before installing your Clear Voice system is to determine where you want to install the system. Look at the diagram below for an idea of how the cellular repeater works: a. The cell signal is transmitted to/from the cell tower. b. The directional outdoor antenna collects the signal. c. The Clear Voice repeater amplifies the signal and rebroadcasts it about your home/office.
Ideal Internal Amplifier Location: • Inside the building, as central as possible (this is to maximize the coverage area). • In the room where you will be most often using your cell phone. This room will receive the best coverage. To find the strongest cellular signal outside your home or office simply walk around with your cell phone on. You should use a cell phone on the network whose signal you are trying to improve.
Step 2: Setting up the Cellular Repeater Once you have established what part of your home has the best signal, you are ready to set up the Clear Voice repeater system. 1. Temporarily place the directional outdoor antenna in the location with the best signal and connect it to the 30 foot cable. 2. Connect the rest of the equipment as shown in the diagram to the right.
FCC Separation Warning The inside antenna used with this amplifier must have a separation distance from all persons that is at least 20cm. The amplifier must not be co-located or operating in conjunction with any other antenna or amplifier.
Step 3: Aligning the Directional Antenna Special note for iPhone users: If you own an iPhone or iPhone 3G/3GS, you can use the in-built “Field Test Mode” to align the outdoor directional antenna. To use this feature, browse to the keypad screen and enter *3001#1245#* then press dial. In the top left of the screen, in place of the signal bars, the signal level in dBm is shown. A less negative number means stronger signal (e.g. -80 represents stronger signal than -100).
of alignment. Now, to fine-tune the alignment of the outdoor antenna, have the person holding the cell phone move between 20 and 30 feet away from the amplifier. The number of bars on their cell phone should now fall. Repeat the procedure above, fine-tuning the direction of the external outdoor antenna to get the maximum number of bars on your cell phone.
Troubleshooting 1. The CEL and PCS lights on the front of the amplifier unit are yellow or red. If the light labeled CEL (for 800 MHz band) or the PCS (1900 MGHz band) turns YELLOW it means that the automatic level control (ALC) is in action to limit the emitted power. There is no cause for concern and the operation can coninue. If either of two lights turn RED, the input power is exceeding the safe level or the unit is oscillating.
Increasing the height of the directional antenna relative to the repeater unit helps improve the level of isolation. Please contact us by email or phone if you continue to have problems. 2. One of the Clear Voice amplifier’s LED indicator lights is blinking. What is the problem? This may happen if the strength of incoming signals might be very low on a particular channel and below the unit’s threshold. This might happen to the Cell or the PCS bands.
e-mail us. 6. I have less than 2,500 square feet of coverage. The Clear Voice repeater system will only provide a coverage area of 2,500 square feet in open space. Attaining this coverage area requires a reasonably strong signal where the directional antenna has been installed. Attenuation of the signal due to absorption by walls will decrease the actual coverage area; typical coverage areas are between 1,500 and 2,000 square feet.
Common Customer Questions Is it possible to purchase and use an extension cable? Using an extension cable with your Clear Voice repeater is possible, however there is a tradeoff since additional cable attenuates and weakens the cellular signal. If an additional 30-feet of cabling allows you to acquire one or more bars of signal, then we recommend purchasing an extension cable by visiting our website or calling us. Our extension cables come with the required adapter to extend your existing cable.
