Maintenance and care

The touch screen of the supply module is calibrated at the factory prior to delivery.
If however there are increasing problems with stylus operation when activating buttons
or if the touch point for activating a button is clearly miscalibrated, a new calibration of
the touch screen can provide a remedy.
If during calibration, an incorrect area of the screen is touched, the result may be
that the supply module can then no longer be operated with the stylus.
In such a case, a network connection (for example, via WLAN) must be
established (see page 19) with the supply module and the procedure for touch
screen calibration started again.
Proceed as follows to calibrate the touch screen:
Step Action

and keep contact with the display for about 1 second.

After being touched, the crosshair jumps to the next position after
about one second.
