location, or replace with higher gain antenna to increase input signal strength.
7.9.2. Repeater 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:
➢ Firstly check whether the alarm LED is orange. The orange light shows the insufficient isolation.
➢ Secondly adjust the antennas’ directions or locations or enlarge the distance between them.
➢ Thirdly reduce the repeater’s gain by ATT DIP if the above methods don’t work.
The following measures can also be tried:
➢ Use the roof of the building to enlarge the isolation (Please try to place the donor antenna and
server antenna in different floors).
➢ Use some obstacles (Such as wall).
2) The repeater’s power is on but the phone is not connected into the network and still can not
communicate.
➢ 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.
➢ 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.
3) The repeater has alarm OFF status
➢ Reason: the repeater breaks down.
Solution: Please check the power adaptor to see if it breaks down or not, then take off the plug
and re-plug in, if alarm LED maintains off, the repeater break down is confirmed, then please
consult local dealers for warranty.
➢ Reason 2: There is self oscillation if alarm LED turns red after re-plugging in.
Solution 1: Change the direction or location of donor or server antennas to enlarge the
distance.
Solution 2: Use barriers (like buildings) to increase isolation.
Solution 3: Reduce the repeater gain by DIP switch.
