9.4.2. Booster can not communicate in Power-ON status
1) The power is on but it has a signal fluctuation or a flash signal. The phone call can not be achieved.
It shall be caused by the insufficient isolation between donor antenna and serve antenna.
Please take below measures:
¾ Firstly check whether the alarm LED is orange. The orange light shows the insufficient isolation.
¾ Secondly adjust the antennas’ directions or locations or enlarge the distance between them.
¾ Thirdly reduce the repeater’s gain by ATT DIP if the above methods don’t work.
The following measures can also be tried:
¾ Use the roof of the building to enlarge the isolation (Please try to place the donor antenna and
server antenna in different floors).
¾ Use some obstacles (Such as wall).
2) The booster’s power is on but the phone is not connected into the network and still can not
communicate.
¾ Reason 1:
There are loose or wrong connections in the repeater system.
 Solution:
Please try to fasten the connections between the different parts of the system.
¾ Reason 2:
The signals received by donor antenna of other operators nearby are too strong. (For
example, the other operators’ signals are 10 dB stronger than the needed signals.)
 Solution 1:
Change the direction of donor antenna or its installation position, so that the gap of
signal strength is reduced between operators.
 Solution 2:
Use barriers (like buildings) to block signals of other operators.
