I have 3.4.4 now. Not sure what update the current tune is on. I will make a copy and play around. I will also run a smoke test for the vacuum. That will give some sense of direction. Onward and upward.
Right-click CurrentTune,msq that was sent to you. Open with notepad.
The firmware the current tune was generated is in the 4th line:
<versionInfo fileFormat="5.0" firmwareInfo="MS2%2FExtra+3.4.4+release................................>
It will change when you load it into the MS, so look at the one they sent you before you load it.
When you load, it may throw a lot of error messages depending on how old the firmware was.
Anything before 3.4.0 could be a problem.
Usually you can ignore any messages.
