4.5.21 Calibrate the GUI Panel
The GUI touch screen can be calibrated to make sure that it responds accurately when
touched. If the GUI is not calibrated, the screen may seem unresponsive. You must
use a suitable tool to calibrate the GUI panel. This can be the tip of a ball pen or PDA
stylus.

Caution: Always use gentle pressure and never use a sharp object to touch the GUI
screen, as this can cause damage.
