in line.

the user is prompted to repeat Step 3.
With the TP37and TP27-10, calibration is saved even in the event
of a power failure.

able in the case of extreme adjustments. In this case, restart the TP and repeat
the touch calibration. Any extreme calibration error is corrected by default val-
ues which are restored on restarting.
