For maximum precision in signal level testing, switch your cell phone into Field Test Mode and see dB parameter. Thecloser dB signal level to 0, the better cell phone reception you’ll get.• -105 to -100 = Bad/drop call• -99 to -90 = Getting bad/signal may break up• -89 to -80 = OK/shouldn't have problems, but maybe• -79 to -65 = Good• Over -65 = ExcellentYour task is to get at least -79dB signal to ensure reliable communication and strong signal inside the building.Remark:• Reduce attenuation values * — by ensuring the isolation level• Increase output power * — recommended ways: to adjust outdoor antenna direction/location, or replace it toan antenna with higher gain to increase input signal strength.7.4.2 Repeater can not communicate in Power-ON status1. 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. 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 indoorantenna on different floors).
