Special features
The touch controller, integrated in the front, is designed to automatically compensate for changes in the surface tensions of the touch sensor (e.g. due to large temperature fluctuations). As a consequence, however, this feature may initiate an automatic calibration when exactly the same point is continually pressed for a while (>15 seconds).
If this happens,
Do not touch the screen touched for a short time. It is then recalibrated to the original state.
An incidentally located background function is activated by the software ProTool/Pro if touched when setting the touch parameters in the window Microtouch → Touchsettings: Desktop or when the screen saver is activated.
Warning
Do not touch the screen:
•during the PC boot routine (until the acoustic BEEP signal),
•when plugging USB components in or out, and
•if the warning message Do not touch the screen... appears. Wait at least 1 second after the message has disappeared.
