User assistance
See also: User interface: Assembly/disassembly.
- Operating instructions are not dependent on language or literacy.
- Primary users can correctly set up and operate device without assistance.
- Setup, operation, and maintenance instructions are communicated without text and incorporated into product packaging (rather than a separate document).
Key indicators
- Product setup, operating instructions, and maintenance procedures are minimized and illustrated graphically on product packaging.
- Critical information may be provided on the device itself.
- If information is displayed on the product itself, it is effectively permanent over the life of the product (e.g., molded in, rather than adhered).
- Avoid printed instructions on surfaces subject to cleaning with abrasives.
- Indicates component assembly order and orientation.
- Multiple views or photos of the device in its correctly assembled state are included.
Notes and exceptions
