Congratulations! I did the same thing some time back. ;O)

No worries. You will have to replace the 3.6V backup battery on the CPU board.
Or to retrace the tought a little. It is easy enought to do the sensitivity
calibration. Just follow the manuals and be happy. However, each time you turn
your 5372 off I bet you loose it. Replacing the backup battery did the trick
for me. So, just replace it and do the full calibration run and you are all
set. It is really that trivial usually.

Cheers,
