again after a moment.
▪ When using touch function at the display edge, there may be a slight gap between touch position on the
screen and where you touched. It is the specification and not a failure of product.
The response of the touch screen is not correct
▪ Avoid direct sunlight or strong light on the screen.
▪ If there are some obstacles near the TOUCH screen, it may malfunction.
▪ Sensor bar module may be dusty or dirty, wipe gently with a soft cloth.

touch response.
