Final answer:
A sales associate who forgets information about a portable Bluetooth speaker should review training materials, ask for help from a supervisor or experienced colleague, and utilize online resources to regain product knowledge.
Step-by-step explanation:
If a sales associate forgets information learned in a class about a portable Bluetooth speaker, the first step they should take is to review the materials provided during the training session, such as a product manual or employee handbook. If the materials are not readily available, the associate should not hesitate to ask a supervisor or a more experienced colleague for a quick refresher on the product details. Moreover, many companies have online resources or product information databases which can be used to reacquaint oneself with the product's features and specifications. Taking initiative to relearn the product highlights the associate's commitment to providing accurate and helpful customer service.
