Fault analysis and processing

1) Run the touch screen calibration program. (Start - Settings - Control Panel - Acoustic Screen ---Capberate Button).

2) If it is a newly purchased touch screen, please try to delete the driver, and then power off the main unit for 5 seconds to power on and install the driver from scratch.

3) If the above method is not possible, it may be that the reflection fringes of the sound wave screen during transportation are slightly damaged and cannot be completely corrected, and you can violate the calibration bullseye at an equal distance in the opposite direction (relative to the direction contrary to the mouse) for positioning.

4) If the sound wave screen is not allowed after a period of use, it may be that the reflective stripes around the screen or the transducer is covered by dust, if you use our company's KA cabinet, you can open the upper cover with a dry soft cloth dipped in industrial alcohol or glass cleaning liquid to clean its appearance, and then run the system from scratch, pay attention to the upper left, upper right, lower right transducer can not be damaged. Then power off to start the computer from scratch and calibrate from scratch.

5) There are water droplets or other soft things stuck to the surface of the touch screen, and the touch screen is misjudged to have a hand touch, resulting in the appearance of the sound wave screen is not accurate, and it can be removed.
