Measures: The below actions are recommended to eliminate "Quick Flashing Green"
and "Quick Flashing Red".
1. Adjust the antennas’ directions or locations to lower downlink received signal
level.
2. Slowly reduce the downlink gain using the Manual Gain Controls.
3. If the above methods don’t work, reduce the booster’s gain with an external
attenuator in line with the outdoor antenna or replace with lower gain antenna.
Target: The overload issues are fixed when the Alarm LED is "Green" or "Slow
Flashing Green". Please note that a "Green" LED indication may result in smaller
coverage area. This can be improved by adjusting the outdoor antenna to receive a
stronger signal.
3. Status and Definition of ISO indicator; ISO LED only works for downlink signals
