The buttons on the touch panel do not respond at the correct position.
If this happens, use the calibration function in the menu.
Notes
- If you did not press the right spot, try the calibration again.
- Do not use a sharp-pointed object for calibration. Doing so may damage the LCD screen.
- You cannot calibrate the LCD screen if it is rotated, or closed with the screen facing out.
If the issue is still unresolved, the product may need to be repaired.
