It adopts digital ALC and anti-interference technology, which can detect the signal quality in the coverage area in real time and auto adjust the working status accordingly. The signal repeater can automatically attenuate the gain of uplink and downlink, according to the detected signal intensity and also when there is insufficient isolation between inside and outside antenna, to avoid self-oscillation. When there is no mobile users in the coverage area, the device will auto shut off uplink, to save power consumption and decrease the interference to the base station. This signal repeater series are well suited in South America and Europe, available to amplify 2G 3G 4G or 5G networks of several mobile operators. With features like elegant appearance, compact size and easy to install and maintain, it has an output power of 20dBm which enables the device to cover an area of up to 500 with proper installation. That makes it an excellent option to solve weak signal problems of house, office, elevator, basement, etc. Product Features LCD screen to display device's operating parameters clearly, button control make it easier to operate the device Available to support several mobile operators' networks simultaneously Low power consumption, low interference Manual gain control, with 1dB step to attenuate the gain among the range of 31dB Digital ALC technology, auto limit the output power to ensure stable signal coverage Anti-interference technology, auto detect the isolation in real time. When isolation is 1 C20M-5B Five Signal Repeater insufficient, device will auto attenuate the gain, to avoid self-oscillation occurs to interfere the base station Uplink dormant function, when no mobile users in the coverage area, device will shut off uplink output, to save power consumption and not interfere the base station.

Check real-time gain and power Press the `MENU' button to view the real-time gain (Gain) and input (Rssi) output power of the corresponding system(Figure 7). Figure 7 f. Self-oscillation Elimination and Auto Shutoff Function The device will auto detect the isolation in real time. When there is insufficient isolation between outside and inside antenna, the device will auto attenuate the gain to make it work normally(Figure 8,the "run" indicator is in orange ). When severe insufficient isolation occurs, the "run" indicator is in RED (Figure 9). Then the device will be turned off, the direction and height of the antennas should be adjusted until there is sufficient isolation for device's normal working.

The expected sites of the holes are as the following diagram. 7 C20M-5B Five Signal Repeater 3) Put the expansion pipes(size: 8mm) into the 4 drilled holes. 4) Align the fixing holes of the repeater with corresponding holes on the wall, and drive 4 M6*40 screws into the expansion plugs with screwdriver and fasten the repeater firmly. Antenna Connection Take suitable outside antenna and inside antenna according to the characteristic of the 8 C20M-5B Five Signal Repeater coverage area. Installation and connection of the antennas should follow the requirements as following: 1The outside antenna should be installed at the place with the strongest signal and towards BTS. 2The length of the cable, which connects the outside antenna and the repeater, should be less than 20 meters. 3Wrap the waterproof tape around the connection part of the outside antenna and outdoor cable, in case of oxidization or corrosion. 4The indoor antenna should be placed 5m above lower than the outside antenna, with its direction not towards the outside antenna. 5It will be better if there can be a wall between outside and inside antennas. 6Outside antenna should connect to BTS port of the repeater while inside antenna to the MS port. Starting 1If possible, please connect the grounding screws of the repeater and grounding of the electrified wire with cable. 2Make sure the feeder cables between repeater and antennas are firmly connected. 3Connect the DC plug of the 12V/3A power adapter to the DC+12V port of the repeater. Then put AC plug connecting to the nearby 220V power outlet. 4Check if repeater can work normally or not, by checking the operation parameters on the screen, according to the guides of the previous "Operation and Display Description" part. 5Test signal intensity and dialing quality with mobile phone in the repeater coverage area. Maintenance and Repairing Frequently Ask Questions and Solutions Problems Reasonable Causes Solutions Screen and indicator lights are off Disconnected to power source Check the power adapter and power outlet, and reconnect it "Run" Indicator Red Isolation between outside antenna and inside antenna is insufficient Change the distance & direction of outside & inside antenna, until I.S.O is not flashing 9 C20M-5B Five Signal Repeater Everything is okay after power-on, but no improvement in signal The network of SIM card does not comply with that of signal repeater Replace SIM card or repeater The inside antenna is not successfully connected Fasten the connection of inside cable and connectors The inside antenna is damaged Replace the inside antenna Effectiveness of the repeater degrades after working for a while The outdoor antenna is damaged The outside antenna get loose and is not towards the BTS Feeder is damaged Replace the outside antenna Change the direction of outside antenna and fasten it Replace the feeder Notes Power-off is recommended in the following situations.
