We purchased a Webex DX80 and when we turned it on we have a message on the screen saying Security Risk System Passphrase Not Set. When reading a getting started document published in 2017 it says:

When I'm looking at my DX 80 I don't see a username anywhere.

Am I missing something? Also, I am running CUCM 12.5.1 and looking at the Product Specific Configuration Layout for the DX 80. When I click on the ? to look for a description of the different settings, everything says "No description available for this configuration" Does anyone know where I can find a description of these settings?
Thank you,
