Solution to the insensitivity of the touch screen in the vibration knife control system

When the touch screen of the vibration knife control system is not sensitive, the following methods can be used to handle it:

1. Calibrate the touchscreen through the menu
   If the touch position is offset, inaccurate, or requires multiple presses to respond, first enter the “Menu” on the control panel and locate the “Touchscreen Calibration” or “Touch Calibration” option. After entering, crosshair marks will appear on the screen one by one. Follow the prompts and accurately tap the center of each crosshair using your finger or a stylus until the system indicates that calibration is complete. Return to the main interface and test whether the touch response has returned to normal.

2. Force entry into the calibration interface when the touchscreen is completely unresponsive
   If the touchscreen is severely misaligned or partially nonfunctional and you cannot access the menu, press and hold a blank area on the main interface for several seconds. The system will automatically enter the touchscreen calibration interface. Then follow the prompts to tap each crosshair in sequence to complete the calibration. After finishing, it is recommended to restart the device and check whether the touchscreen sensitivity has been fully restored.
