attention: Input signals may be not enough
Red
Meaning: overloading or self oscillation, strong input signals

antenna,then connect the MS port to load, if the red light
changes to green or orange, which means the isolation of

please adjust the isolation.
If the red light still turning on that means over accepting of
donor antenna or strong interference, then please adjust the
