Remark:
Reduce attenuation values *
— by ensuring the isolation level
Increase output power *
— recommended ways: to adjust outdoor antenna direction/location, or replace it to an
antenna with higher gain to increase input signal strength.
7.4.2. Repeater can not communicate in Power-ON status
1. The power is on but there is a signal fluctuation or a flash signal. The phone call cannot be made/received.
It shall be caused by the insufficient isolation between outdoor and indoor antennas.
Please take the following measures:
- Firstly check whether the alarm LED lights. Compare with the description from the 7.3. section The light may indicate
the isolation is insufficient.
- Secondly adjust the antennas’ directions or locations or enlarge distance between them.
- Thirdly reduce the repeater’s gain by ATT DIP if the above listed methods don’t work.
The following measures can also be helpful:
- Use the roof of the building to enlarge isolation (Please try to place the outdoor antenna and indoor antenna on
different floors).
- Use some obstacles (Such as walls).
2. The repeater’s power is on but the phone cannot get connected to 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 different parts of the system.
Reason 2:
The signals received by outdoor 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 the outdoor antenna or its installation position, so that the gap of signal strength
