Once the debugging for the complete unit is finished, please set relevant functions for the unit
according to the actual functional requirements of the project. Refer to relative technical materials for
the detailed operation method. If there is no special requirement, skip this step directly.
When delivery it to the user for operation, explain the precautions to the user.
