The touchscreens of the DLT-V72 is
already calibrated at the factory and
therefore and does usually not need to
be recalibrated.
However, the operating systems MS
Windows 7 Pro, Windows 8.1 Industry
and WE8S do permit recalibration of the
touchscreen via software (Menu
Control Panel -> Tablet PC Settings).
This resets the sensitivity of the
touchscreen to an operating system
default setting, which can result in
poorer detection of taps on the screen.
You can use Reset to reset the software
recalibration.
Remove all external storage
