During use, the machine suddenly gets locked and technical engineers need to be contacted. This is a headache, so we can only contact the engineer and send the unlock interface to the agent/manufacturer

Important: After sending, do not shut down, restart, or power off

Here are the methods

Unlocking steps
1. Click on the system maintenance code box and enter the code
2. Select the right side of the input box (unlock) and mark it as "red"
3. Press the top right corner of the screen (to return to the operating interface) to proceed
