Which of the following is not a responsibility of licensed hearing aid dealers?

The aspect of ensuring customer satisfaction at all times is not a defined legal responsibility of licensed hearing aid dealers according to General Statute 93-D. While customer satisfaction is certainly a goal for any business and can be important for client retention and reputation, it does not fall under the regulatory responsibilities or duties outlined for hearing aid dealers.

In contrast, providing accurate information about products, fitting hearing aids based on professional guidelines, and staying updated on advancements in hearing aid technology are explicitly emphasized as essential duties. These responsibilities are critical to ensure that clients are well-informed about their options, receive proper fitting of their devices, and that dealers maintain a level of professionalism and competence in a rapidly evolving field. Prioritizing customer satisfaction, while important in a service-oriented industry, does not align with the regulatory requirements that govern the practice of hearing aid dealers.
