Bradley,
I have conducted additional testing around the “static” sound your referring to. I am aware of the noise as we heard early on before we finalized the sounds in the devices. That said, we have not been able to recreate it in our test unit. I have configured the sound settings in every different configuration to see if we can cause this to start and have not been successful in doing so. Is there any additional information you can provide on the sound issue. You stated it happens on chime notifications, do you also hear on it on exit or entry tones?
Any additional information that you can provide would be greatly appreciated. If we can recreate it, I am provide engineering with the information needed to address the issue. Please review your display settings, let me know what you have set for Volume Settings, Brightness Settings.
Also do you have Chime, Voice, or Chime/Voice enabled?
