New Replacement Cable Box Setup

Received via UPS a replacement cable box (set-top box with clock and blue power button that connects with coax to wall) last month - August '2021.

When I powered it, the setup ran through a quick pairing of the remote which works fine but there didn't seem to be anything that looked like an activation of the box and the picture on the tv was pixalated.  I restarted the box via the help screen but that didn't seem to have any effect so I did a system refresh via the help screen that got the tv picture to normal.  When  I called about another issue the automated trouble shooting process said that the cable box showed errors and that a restart should resolve them but a check of the automated trouble shooting process later after the restart indicated that the box still showed errors.  Did I corrupt something in the operating system of the box when I restarted and then refreshed it upon initial use?  Should I have called technical support at that point?  It seems to be working alright but am concerned it may not be delivering the best possible performance with the box showing "errors".  Additionally, the "technical support" representatives I've spoken to haven't really been able to answer the question and their solutions are usually to unplug it or send a refresh signal  to the box anyway.  Any clarification would be appreciated.  Thanks.
