		side may be caused by highly reverberant rooms. If you are experiencing poor audio
		reception, add more sound absorbency to the room and speak in close proximity to the
		microphone.

		Degradation in audio quality can also be caused by faulty microphones or dust and debris
		on the microphones. Do not use any kind of liquid or aerosol cleaner on the camera that
		includes microphones. A soft, slightly damp cloth is sufficient to clean the top surface of
		the units if necessary.

		Ensure both ends are not muted. Verify that the audio out cables are properly connected
		to the monitor and that any external speaker systems are powered and configured
		correctly.
