Initialization of touch panel controller (calibration of touch panel) is carried out during period between power supply turning on and start of touch panel operation (t1+t2+t5), therefore please do not touch surface with finger, hold hands near touch surface, nor put conductive material like metal on touch panel.
If the calibration is not able to be carried out successfully at the initialization process, touch panel
may not work properly for sometime.
