Please follow the instructions below to position the cap into the charging dock. The cap should be positioned down from the port so that it is completely below the port, as seen in the photo. It may take a bit of practice to know exactly where and how to line up the motors.
The motors should then slide into the charging dock. Please do not force the motors into the dock, as this may damage the connection or charging ports.
If you are still having difficulties, please don't hesitate to reach out so that we can provide additional assistance.
