6.How to change the cable connector?

When attaching the connector:
①Align the male and female end of the connector, ensuring the notch of the male end is in parallel with the raised dot that's inside the female end. Plug the male end until it is in an appropriate position.
②Rotate the female end in an anticlockwise manner until it is tight to lock them.

When detaching the connector:
①Rotate the female end in a clockwise manner until the female end can be pushed front and back to unlock them.
② Pull the male end to detach the two connectors. (Objects that can generate greater friction like tissues or a strip of cloth can be used to help to detach.)
