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. If the system shows “Device was damaged” note, it means that the uplink/downlink was damaged. Contact customer service for repair. - Page 16 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. - Check if it is necessary to adjust the direction of the indoor antenna.
- Page 17 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 indoor antenna on different floors).
- Page 18 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.
