Before purchase, please confirm your signal frequency
If 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 Dual - Band Booster kit is designed for 850/2100MHz Band 1/5. 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,pleasefell free to contact us. We will help you solve the problem, please don't worry.
1) Wide Input Voltage：
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) 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.Specification:

Warning:
Before ordering: wrong frequency and only 1 bar or 0 bar outside signal may make booster not working. Please check related frequency sites or call network operator to make sure the right local frequency from base station.After Sale: If any problem with the booster, please contact the customer service and we will try our best to solve.

Note:
1. This booster only works for 850/2100MHz. 0-1 bar outside signal may not be suitable for using it. Before ordering, please check your local signal frequency by calling network operator or checking on some sites.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.
