REPEATER SYSTEM OVERVIEW The picture below shows how simple and fast booster installation is and how effectively it works. A Yaggi or panel antenna (it depends on the booster model and its power), as donor/outdoor antenna, is installed at the top of the roof to pick up good mobile signals from the base station, and sends them through the cable to the booster where the signals get amplified significantly;...

If the device detects self-oscillation between the antennas and says that the system is being adjusted, it means that the system has detected the problem of bad isolation between the antennas and AGC is adjusting the system gain automatically to make the device work correctly. No actions are required from you. - Page 17 antennas or replace the repeater for another model with higher power level. 2. If the signals in small parts of the area have not been improved, please check the following: - Check whether the indoor antenna is installed correctly or not; you may try to change the antenna location to improve coverage.
- Page 18 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.
- Page 19 8. FAQ 1. Will booster increase the RF radiation? No, it will decrease instead. Every cell phone irradiates heavily being in zones with poor mobile signal as a cell phone is constantly in searching mode. The danger is your cell phone is about 2cm to your body, which makes its usage rather harmful.
