Nebraska Revised Statute 38-1511
Chapter 38 Section 1511
(1) Any person who practices the fitting and sale of hearing instruments shall deliver to each person supplied with a hearing instrument a receipt which shall contain the licensee's signature and show his or her business address and the number of his or her certificate, together with specifications as to the make and model of the hearing instrument furnished, and clearly stating the full terms of sale. If a hearing instrument which is not new is sold, the receipt and the container thereof shall be clearly marked as used or reconditioned, whichever is applicable, with terms of guarantee, if any.
(2) Such receipt shall bear in no smaller type than the largest used in the body copy portion the following: The purchaser has been advised at the outset of his or her relationship with the hearing instrument specialist that any examination or representation made by a licensed hearing instrument specialist in connection with the fitting and selling of this hearing instrument is not an examination, diagnosis, or prescription by a person licensed to practice medicine in this state and therefor must not be regarded as medical opinion or advice.
