Q. Smoke and/or strange smell issuing.
Update Time:2012-06-11
Q. Smoke and/or strange smell issuing. A. Check if polarity of the power is correct. Check if voltage is impressed appropriately. Check if somewhere on the controller board is shorting out (check the backside as well). Make sure that power is not doubly supplied to both USB terminal and supply terminal. Make sure that the unit is properly grounded. Make sure that it is not connected to another power supply. *1 Calibration ... Task to correct the touch positions by driver software. *2 Touchscreen with back shield ... Touchscreen with coating on the backside that will improve signal stability.
