1.1 Anti-self-excitation function
During the installation of the device, the isolation of the antenna is automatically detected. If the installation requirements of the system are not met, the automatic control of the device reduces the gain, protects the device and the network is not disturbed. After the device is installed, the isolation is automatically detected in real time, and the gain is adjusted according to the change to ensure that no self-excitation occurs, and network interference caused by abnormal operation of the device due to changes in the installation environment is avoided.
1.2 Device gain is automatically adjustable
The mobile partner has an active ALC function and a microprocessor-controlled gain digital attenuator. The gain dynamic automatic adjustment ensures high reliability and high stability of the system.
1.3 Uplink and downlink automatic linkage commission
After the system is powered on, the system will automatically detect the input power and control the output power. After calculating the downlink gain of the system, it will automatically adjust the system's uplink gain, maintain the system's amplification balance, and realize the device's uplink and downlink automatic linkage debugging. The gain of the control system is less than the path attenuation of the signal, ensuring that the micro-power repeater does not have any interference noise to the network, ensuring that one base station can carry more mobile phone partners.
1.4 Easy installation, compact structure
With perfect working status indication, different working status can be displayed, and adaptive control can be realized, which makes product engineering installation more convenient and can be installed without the cooperation of instruments. The equipment is small in size, no need to rent a house, reduce the coordination of the property, and reduce the cost of use.
1.5 Remote power supply
The entire system consists of one host and four remote units. Five devices only need one adapter to supply power for remote power supply. The signal line and the power supply line are combined into one, eliminating the need for wiring and finding a suitable power supply. Adapt to different installations.
1.6 Low Power Consumption
The equipment has low power, small volume and energy saving. The signal emitted by the device is only the megawatt level, no electromagnetic pollution, and will not bring any health hazards to people. It is a low carbon green product.
1.7 Remote monitoring function (optional)
In addition to monitoring the working status of the micro-chamber, the near-end machine can monitor each remote coverage unit and display it in real time. At the same time, it conforms to the China Unicom Repeater Integrated Network Monitoring and Management Protocol specification and can access the Unicom Repeater Integrated Management Platform for alarm monitoring.

DESCRIPTION |
| STOP (smart mode switch button) |
Press this button to switch between the smart mode and the normal mode. When the STOP button is pressed, the device enters the normal mode. If the SMART LED is lit, the device enters the smart mode. |
| -gain reduction button |
In the normal mode, pressing this button will reduce the gain by 1dB and by up to 31dB. In smart mode work, pressing this button has no effect. |
| +gain increase button |
In the normal mode, pressing this button will increase the gain by 1dB and increase by up to 31dB. In smart mode work, pressing this button has no effect. |
