Android : setting→about phone→status→network ,dbm display shall be at -90dbm to -95dbm around ;
IOS : dial *3001#12345#*, dbm display shall be at -90dbm to -95dbm around ;

Samsung phone .Holding the phone to the outside. Dial: *#0011# →ServiceMode→

4.Plug the power adaptor,power light will be lighting ,when the outdoor antenna receive the strong signal the LCD will be display the signal Please note that,when you find signal twinkling and have no full signal display that means have no signal input and you need to check your outdoor antenna position.

TIP: An outdoor antenna should be "isolated" from the internal antenna, that is, there must be constructive obstacles (walls, partitions, etc.) between the antennas.

When the distance between the external antenna and internal antenna is not far enough, both antennas will receive signal from the other one, then your phone will not receive any signal.

A mobile phone signal repeater provides the ultimate solution in any area where Cellular communications can not work well due to leak of signals,the repeater Device features easy installation & operation ,build-in indoor antenna and no Interferece,it could also improve indoor electromagnetism environments. Protract cellular battery life and reduce radiation of cellphones. A mobile phone repeater is ideal for house ,home,office use. High gain ,easy installation and operation. Full-duplex,singal-port design,build-in power supply. Use ALC technology ,adjust extent automatically. LED light working &signal condition indicators. Big linear power,control intermodulation & scatteration stably. Problems and solutions ( important ) , please read : All booster will be tested before shipping to ensure quality , if you dont know any about booster and installation please start from 0 as below . 1. After power connected ,if LCD does not display or power LED is not on ,it means booster is defective ,kindly choose a friendly to solve it ,we accept to reship or refund. Andy dispute or negative will cause you on black list and an uncooperative solution ; 2. After you connet cables and antenna onto booster ,Lcd display 1-3 bars, you need to change your external antenna to a better place to gain stronger signal, if you use small pin antenna ,please upgrade it to a panel or a yagi ; If you can not find a place with good signal to enable booster with full bar display ,it means your outdoor signal is too bad ,booster will not work . So please kindly contact for a solution to return . 3.
