What I am saying is that the inherent tolerance in that machine is more than 5 times that large (at least probably .0004 as opposed to two microns which is ~0.00008). If you are making parts with a tolerance of 2 microns, you won't get it on that machine, which is why I have no idea how anyone familiar with common machining would even bring up anything about 2 microns being a problem (requiring the installation of a backup battery).

I had heard (as apparently we received the exact same machine from the same sponsor here at RIT) that it was actually .001" that it would drop. Either way, I don't think it's particularly important what the amount it drops, simply that it drops somewhat and wasn't really suited to the application that the sponsor attempted to use it for (which is why they decided to donate them).
