These instructions work for my model (8.4" touchscreen )
Press Menu key on front of Lilliput frame
Press the > key three times to select the Misc. Control
Press Meny key
Press the > key three times to select the reset
Press Meny key
This causes the screen to reset and it won't work until you reboot your system.
This fixed the error
"Access EEPROM fail!! Please check again."
when I first tried to calibrate it.
BTW, I've had this unit for about 20 minutes. Thanks to those who posted on this topic before - helped me get past first hurdle.
Also, my unit beeped every time I touched it (making me think that the PC was not happy). This appears to be the default setting for the touchkit. To turn sound off, open the touchkit configuration utility and uncheck "Touch Down" check box on the Settings tab.
