improve coverage.

- Check if it is necessary to adjust the direction of the indoor antenna.

- Check whether it is necessary to add one or more antennas to enhance the coverage in special areas.

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.
