C. Without Hearing

At least one mode shall be provided that allows full use of product without using hearing, directly or with users' AT.

D. With Limited Hearing

Where audio information is important for the use of a product, at least one mode shall be provided that allows full use of product with enhanced audio, directly or with users' AT.
