Welcome you all to order. Any problem? Pls do not hesitate to write an email to customer services to solve. We provide the best sale service and after sale service.Thank you.Cell Phone Signal Booster Repeater 900 /1800 /2100MHz 2G 3G 4G Ehance Voice Data900/1800/2100MHz BoosterBefore purchase, please confirm your signal frequencyIf your phone is Android system, you can download an App called "LTE Discovery" to confirm the band and frequency.If your phone is Apple system, please dial the NO. *3001#12345#* then click "Serving Cell Info" to check frequency and band.Note:1.This Single Band Repeater kit is designed for 900/1800/2100MHz Band 8/3/1.Because different regions have different frequencies, the booster works only at the correct frequency.If the frequency is incorrect,the booster will not work.If this problem occurs, please contact us and I will solve it for you.2 .If you have any questions when you receive the booster,please fell free to contact us.We will help you solve the problem,please don't worry.Why you need us? 1) Wide Input Voltage: Input DC Voltage Range 5-15V 2) Self-oscillation Elimination: The system detects self-oscillation, first reduces the link gain, then detects the loop, and finds that the self- oscillation is eliminated, the system returns to normal working state, otherwise, the power is turned off to prevent interference signal. 3) Inactivity Mode: When no user calls, the device works in standby mode, the uplink power amplifier is switched off, and the static power is decreased by 30%, so as to achieve the purpose of energy saving. 4) AGC (Automatic Gain Control): When the downlink output signal is too strong or self-oscillated, the uplink and downlink can automatically reduce the gain and reduce the interference signal. 5) Automatic Power Shut-down: When the self-oscillation happens, and the link attenuation value reaches 20dB, the MCU sends out the instruction and shut-down the PA. 6) MGC (Manual Gain Control): In order to install the booster conveniently, all frequency band of the booster have the Gain attenuation adjustment function, the adjustment scope is 0-20dB. You can rotate the Manual Gain Control Knob to the OFF state and turn off the corresponding frequency band. 7) ALC(Automatic Level Control): Automatically adjust the output gain down to optimal figure while the output gain is above the optimal figure by the ALC circuit, this can greatly optimize the calling quality, data transfer quality, avoid the signal self- oscillation, and also very much reduce the interference to the cell tower, even if your house is very close from the cell tower, you don't need to worry about the interference and the trouble caused.Benefited: 1. Significantly improves voice and data quality. 2. Greatly reduces disconnects and drops call. 3. Works wirelessly with multiple cell phones simultaneously. 4. Easy to install and operation.

This booster works for 900/1800/2100MHz. 0-1 bar outside signal may not be suitable for using it.Before ordering,please check your local signal frequency. 2. For installation, you are supposed to pay attention to the following. Points: 1)There is separate wall between indoor and outdoor antennas to make two antenna signal not interfere with each other. 2)To avoid interference, please make the distance of indoor and outdoor antenna more than 10 meters, let them not pointed at each other.
