The Lifesize Phone HD has a diagnostics test built into the phone itself that tests the on-board features. You may be asked to run the diagnostic test to if a microphone, speaker or component that has gone bad.
Swipe left on the touch screen to get to the System Tab
Tap the System Tab , then tap the Health Tab
Scroll down and tap the Phone Diagnostics Tab
Make sure the room is clear and not in a meeting, there is an audio test that can be a bit loud during the Diagnostic Test.
Make sure to take a picture of the screen if an error was returned as a result of the Diagnostics Test and update an existing case or create a new case online or by calling into support.
