Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If use in computers rather than dedicated word processors
Computer input device controllers fall under 8471 parts, not note 11 word processors.
If functions as motor controller rather than input interface
Different 8537 panel functions determine PCA classification path.
