To Buyer ,

All of the repeaters need good signal source outside your house ,

please make sure there\'s at least 3 bars signal outdoor , >-75dBm is better. You can use your phone to test it .

If the signal source not good outside your house , I am afraid the repeaterCAN NOT work for you .

AND when you received the parcel have any problems , just contact our professional customer service firstly .

We will try our best to solve your problem . Don\'t open dispute on your own . (That\'s not friendly buyer .)

Hope you guys will understand it ~

LCD display shows signal strength.

If lcd display is fashing and blank, it means the outdoor signal is weak or the connection between outdoor antenna and booster is not good. Please put the outdoor antenna at a higher place so that the antenna can get stronger signal. Or check the connection between the outdoor antenna and booster.

If LCD display shows full bars signal, it means the booster get strong signal. (Unless it is not interference ) --- The indoor and outdoor antenna should have enough islation , at least 8 meters distance .

Installation Approaches

1.Fix up outdoor antenna(usually use the yagi antenna) on the housetop and point to signal tower.

2.Connect outdoor antenna to "BTS" in repeater via cable.(Notice:the machine must be away from outdoor antenna for more than 10 meters)

3.Connect indoor antenna(usually use panel antenna) to"Mobile" in repeater via cable(the machine must be away from indoor antenna for more than 1 meters)

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.

Working principle:

1.Outdoor antenna received the signal from signal tower.

2.Then,through cable sent the signal to the indoor repeater.

3.The repeater accepts and improvs the signal.

4.After that,the fine signal goes into indoor antenna,via cable to your mobile phone.
