Electronic device, apparatus and method for displaying a manual

摘要

Manuals of various electronic devices are stored in a portable memory device, and the manuals are displayed on the electronic devices as the portable memory device is connected with the electronic devices whenever the manuals are necessary, so that users easily refer to the manuals. Convenience of the users is improved. The portable memory device is individually utilized, so user satisfaction is improved. The portable memory device storing the manuals is provided to the users free of charge, so the user satisfaction is improved. Wastes and environment contamination caused by book-type manuals are reduced. Since the portable memory device is used instead of the book-type manual, the size of a box for accessory parts is minimized, so that transportation cost is reduced.
