During a meeting with a potential customer, you are asked to explain the difference between two different types of systems that your company is developing. Although you feel confident that you correctly explained the systems, after the meeting you realize that you inadvertently confused some of the characteristics, and partly described a third system that the customer had not even asked about. The systems are still prototypes and there is no publicly available information about them, so it is unlikely that the potential customer will realize that you confused the systems and are not up-to-date on your company's products. What should you do?

First, update your knowledge of the company's product (especially at this development stage).  The purpose is for a demonstration of general knowledge and not for you to provide all the technical details to the potential customers.  So, try to stick to the claims about the product's performance and not the details.

Secondarily, request for the documentation of research and development activities.  This will provide some literature for the sales and marketing efforts to be effective.  Study the available data about the product development, customer requirements, and lifecycle.

Explanation:

In marketing newly developed products, the marketing personnel should bear in mind that effective communication of value to the potential customers is what is required at the initial stage, without too much details.  The effort should be to convince customers of the value of the products under development.
