In step 18, where it says:
"...holding them unit SYSTEM RESET appears in the front panel..."
I believe instead of "unit" it should read "until".

Other than making me scratch my head at that step, the instructions worked great.

I realize that firmware upgrades are supposed to be a quick-and-dirty process. However, I believe that the process can be made more user-friendly if the update tool was written like a wizard with the instructions built in. Each one of the 21 steps could be a "page" asking the user to click "Next" when ready.
