This repeater must ONLY be used for the purpose it was intended for. Making any alternations to the design layout without first consulting with a trained technician can result in interference to the operator’s network and liability by the end user. 2. Please read this entire manual carefully before using this product! 3. Only the power supply that came with the repeater should be used at all times. It is highly recommended that the repeater is grounded and lightning protection used. 4. Do not attempt to open any part of the repeater. This will void the warranty and can cause an electric shock. Electrostatic can also cause damage to the internal components. 5. Please keep away from any heating-equipment, because the repeater will dissipate heat when working. Do not cover the repeater with anything that influences heat-dissipation. 6. Do not place or mount the repeater in a location that is exposed to the elements. This will void the warranty and can cause an electric shock. 1 2

3. Installation 1. The repeater’s main function is to improve weak RF signals to an area. 2. Selecting the appropriate accessories that are compatible with the frequency of the repeater is very important for optimal system performance. An 850Mhz Repeater needs to be used with accessories that supports the 850Mhz band. In the same way, choosing accessories in the 1900Mhz Band needs to go with a 1900Mhz Repeater etc. For dual band or multi-band repeaters, please ensure the peripheral components used supports all the frequencies needed. 3. The signal strength from the outdoor antenna directly affects the efficiency of the indoor coverage. It is very important to choose the location of the outdoor antenna carefully. With this in mind, it is not recommended that the donor antenna be installed in an attic or at the side of a building. 4. The repeater is a two-way (full duplex) signal amplifier. Therefore there needs to be proper isolation between the outdoor antenna and indoor antenna in order to avoid signal oscillation on the repeater. (Interference) There needs to be more than 15dB of isolation above the repeater gain. For example, if the repeater gain is 60dB, then you need 75dB of isolation between outdoor antenna and indoor antenna. 5. The repeater gain is adjustable for both the uplink / downlink individually. Depending on the environment, the end-user may need to adjust the repeater gain to achieve optimum performance and desired coverage. 6. The repeater is designed to amplify the input signal, filter it and retransmit it to the desired area via service antennas. In order to reach the best performance, the outdoor signal should be greater than -80dBm, and not over +10dBm. If the outdoor signal is very weak, then a pre-amplifier may be used. 7. Calculating the Link budget before setting the repeater gain. Link budget calculation: Outdoor signal strength – Loss of accessories (cable, connectors, splitters, Directional Couplers) + Antenna gain (outdoor antenna, indoor antenna) + Repeater gain = Indoor signal strength. 8. For all cellular applications, you need to use 50 Ohm rated coax. Besides affecting voice quality, using any other impedance of coax will put an extra load on your repeater and shorten its life span. 3.1 Installation Procedure Site SurveyInstallation PlanningLink Budget CalculatingInstall Outdoor AntennaCable InstallationInstall RepeaterInstall Indoor AntennasSignal MeasurementGain AdjustmentTest for Call QualityTrouble Shooting7 8
