*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.
