ELO Touch Screen Support
Upon connecting an ELO Touch Screen to your thin client you will be
presented with a calibration screen on first boot to ensure your unit
functions properly.
There are two ways to calibrate your ELO Touch Screen device when
attached to your thin client.
Calibration
– Option 1
Upon first boot of the operating system, you will see a gray calibration
screen with a countdown timer in the middle if an ELO device is found.
Use your finger or a stylus to tap the center of the red cross that displays
in the upper left-hand corner. Try to get as close as possible to the small
circle in the center of the red cross.
Another calibration spot will appear in the top right-hand corner. Use
your finger or a stylus to tap the center of the red cross. Repeat for the
calibration spots that appear in the bottom right-hand corner of the
screen, and then the bottom left-hand corner of the screen.
NOTE: If the calibration is inaccurate, the calibration tool will ask you to re-try
the process until a more accurate reading is achieved. You can wait until
calibration is achieved or press any key to cancel the dialog at any time.
