I am receiving an error message that "All UM ports exceeded the busy threshold time" (code 262, subcode 00020) from an NS700. I cannot locate an "error Code" listing that references this code (or any NS700 code list for that matter) in any of the manuals I have (Programming, Installation, User). Can someone point me in the right direction? It is not causing a problem that we are aware of but if there is a setting that I can change, I would like to do so.

Thank you in advance!

Have you looked through your Panasonic Tech Bulletins? Sometimes those will show issues that are "not a problem, and will be fix in next software update".

You might also be able to reach out to Panasonic:

[7.1.4 Error Messages basically only helps with hardware issues not software timers]

I believe it means all ports were busy for extended periods of time. 2 port system answering with high call volume?

tech support can't seem to help me with error codes.. Seems like they would be more helpful to the manufacturer than to the tech in the field.

I was told that they are in the service manual? Who are you calling for tech support?
