2. After entering the setting interface, double-click the icon named "OP".
3. Click the "Touch" option in the small window that pops up. (Other options may be delayed due to no calibration).
4. Click the "Recalibrate" button under the "Touch" option, and then click the cursor in the displayed screen.
5. After clicking the cursor in turn, there will be a countdown of 30 seconds. In the meantime, you only need to touch the screen and click "OK" at the top right, and the whole setup process is completed.
Note: In the Siemens touch screen control panel, the operation-touch-recalibration and calibration crosshairs will be displayed in five positions. Touch the center of the calibration crosshair at each position. If the center of the calibration crosshair is not touched, the process will be repeated. After touching the calibration crosshairs in different positions, a dialog box will appear. Please touch the screen within 30 seconds. Save the new calibration value. If it exceeds 30 seconds, the new calibration value will be abandoned and the original calibration value will still be valid.
