Calibrating the Active Digitizer (i440D only)
Independent from the accuracy of the touch screen is the input
accuracy of the active digitizer (i440D only). In the lower half of
the “General” tab you will see the “Calibration” section.
To begin, choose a screen orientation from the drop down list
and then tap the “Calibrate...” button to start the digitizer screen
calibration routine. Follow the on-screen instructions to
complete the calibration routine and save your input settings.
For maximum accuracy, it is
recommended that you calibrate
both the “Primary landscape” and “Primary portrait” orientations.
NOTE: Calibrating the secondary orientations is not necessary since,
due to FCC certification regulations regarding the wireless
networking transmitter, they are identical to the primary
orientations.
The digitizer
calibration is very
similar to the touch
screen calibration.
Touch the center of
the crosses when
they appear.
When complete,
tap “OK” to save
your settings.
