S.C. Code Ann. § 40-25-70: Duties of licensees to purchasers of hearing aids.

(A) A person who engages in the practice of specializing in hearing aids shall deliver to a person supplied with a hearing aid a receipt which contains the licensee's signature and business address, the number of his license, specifications as to the make and model of the hearing aid furnished, and full terms of the sale clearly stated. If an aid which is not new is sold, the receipt and its container must be marked clearly as "used" or "reconditioned", whichever is applicable, with terms of guarantee, if any.

(B) The purchaser must be advised at the outset of his relationship with the hearing aid specialist that an examination or a representation is not an examination, diagnosis, or prescription by a person licensed to practice medicine in this State.

(C) A person engaged in the practice of specializing in hearing aids shall comply with federal regulations, 21 CFR 801, or related amendments to the regulations. He may not sell a hearing aid to a prospective user under eighteen years of age unless he presents to the dealer a written statement signed by a licensed physician stating that the patient's hearing loss has been evaluated medically, and the patient may be considered a candidate for a hearing aid. This evaluation must have taken place within the preceding six months.
