Touch screen calibration
With the device power-on, if the non-touch area of the touch screen is clicked more than 20 times within 4
seconds, the touch screen calibration mode will be entered. The steps are as follows:
1. Within 4 seconds, click the non-touch area of the touch screen more than 20 times;
2. Stop clicking unless the buzzer is on for 1 second;
3. Enter the calibration mode and click the specified position of the touch screen to calibrate the touch screen
according to the cross line;
4. Return to the screen after calibration.
The display will automatically detect whether the calibration is effective or not, and when the calibration is invalid
(for example, incorrect operation to enter the calibration mode), the display will not be set incorrectly (calibration).
If multiple calibrations of the touch screen do not work, it is often because the touch screen has been physically
damaged, such as the touch screen is broken.
