Please Read Carefully before Buying

PLEASE, focus on signal freqeuncy, instead of the word "2G 3G 4G" in title.

Because we sell all over the world, not only for one country,

Sometimes a device could work well for other people but not for your operator. 

Therefor,it\'s important to find out the frequency of your operator.

The following method could be your information.


 Go outside and turn on 2G/3G/4G (the signal you want to amplify)

And then iPhone: dial *3001#12345#* 
    Samsung: dail *#0011#
If neither iPhone nor Samsung,
please go to Google Play Store to download an APP:
Network Cell Info Lite
See the picture below for details.

What\'s in

Please note: this is repeater only, no antennas and cable. 





How to install 


Step 1: Find a position where could receive great signal,mostly a higher position, like at rooftop. Install outdoor antenna at it and make it toward the base station.
Note: the outdoor antenna shall receive good signal, otherwise the repeater could not work.
Step 2: Connect outdoor antenna to booster at BTS connector with the cable.
Step 3: Connect indoor antenna to booster at MS connector. And it would be better to install it at a height of 2 meters. 
Note: The two antennas shall be totally separated by a brick wall with a distance of at least 10 meters. Otherwise, the signal would intervene to each other, showing full of signal on display, but actually the booster doesn\'t work properly.
Step4: Plug in power supply and done!


Common problem


 Question: no signal on the display and phone  

Solution: adjust outdoor antenna, put it at a higher postion and make sure it could receive good signal from base station.Or please check the freqeuncy of your antenna, if you buy only booster from us. If the frequency doesn\'t match to the booster\'s, it could not work either. 


Question: the display is blinking and signal light isn\'t on.

Solution: Also adjust outdoor antennna as above, because blinking means receiving signal is not stable. Adjust the position and direction of outdoor antenna until it stop working. 


Queation: the signal is at maximum on booster but the signal on the phone does not improve at all

Solution: It is what we called "self-oscillation phenomenon". You need to increase the distance of  indoor antenna and outdoor antenna and separae them with a brick wall. Make sure there is no opening area between them. 

Question: The booster works properly but the signal light is not on  


Solution: Maybe the cable is too long for the booster or   the connection is not well. Please make sure all the antenna are connected well and tightly. It actually does n\'t matter too much as long as the device works well. 



Any other problems about the product or installation, please contact us. 

Thank you!
