The firmware says not compatible, but I know I have the right firmware. I said yes to override and it seems fine.
Yes, I upgraded my 5500HC 7 segment speaker. There is a warning message, but it is only a precaution to ensure that you aren't upgrading the 5500 instead of the 5500HC.

I did have to retype the speaker after the update and then it worked perfectly.
