*When utilizing the configurable microphone gain adjustments, the modulation capability specification
can be met with a 70 mVrms to 3.0 Vrms analog microphone input signal applied to the transmitter.
When a digital audio microphone signal is provided by a compatible Garmin audio panel, the modulation
capability specification can be met with a minimum 70 mVrms microphone input signal applied to the
audio panel.
