cause damage to the special protective coating on the touchscreen surface.
Turn off DCU 220 power when cleaning the display. Cleaning the display with the

power on may cause improper operation.
Do not use excessive force on the display. Avoid placing objects on top of the display as

returning to room temperature.
When there is noticeable discrepancy in the operation of the touchscreen function
