Operating the device
6.3 Configuring the touch screen
5. Quickly touch the corresponding selections one after the other.
The entry is confirmed by a check mark, the next selection is displayed.
6. Confirm all input prompts (arrows, or crosses in the center) until the complete screen has
been calibrated.
Note
If the screen does not respond to touch as expected, check the controller selected under
"1." in "UPDD Console" and repeat the calibration. Only an active touch controller can be
calibrated. A removed touch controller is displayed in red.
If the accuracy of this 3-point calibration is not sufficient, you can clear the "Use eeprom
storage" option box and use the extended 25-point calibration instead.
