1.2 LED Indicators
Warning: The unit has sensed instability due to insufficient isolation between the inside antenna and the outside
antenna, and has reduced the gain of the amplifier. This action prevents oscillation, which can interfere with the
handsets in the covered area and/or the wireless service provider’s base station.
Fault: The gain of the unit has been reduced to a minimum (red) to prevent very strong input signals from overloading
the amplifier. The amplifier will attempt to recover from this condition, initially at 15 second intervals and then at
four-minute intervals.
