(a) A registrant shall accept for repair and other necessary service any hearing aid or accessory thereof, sold or rented by the registrant to the customer, for a period of five years from the date of sale or rental. The repair or service may be made by the registrant or referred by the registrant to the manufacturer or supplier of the hearing aid or accessories or to any other person.

(b) The charge for any necessary repair or service shall be reasonable and no more than that which is provided in any outstanding sale or rental agreement. The registrant shall deliver an itemized receipt showing the repair and service provided and the charge therefor. If the charge for the repair or service shall exceed $50, no work may be performed unless the customer shall have been first advised of the work to be performed, the charge therefor, and shall have approved same.

(c) If the registrant or the manufacturer or other person making the repair shall charge a non- refundable fee for an estimate of the cost of such repair, the customer shall be advised thereof in writing prior to the acceptance of the instrument. The registrant is entitled to retain such fee if the customer determines not to proceed with the repair after receiving the estimate.

(d) In addition to the provision for payment for the specific repair of a damaged or otherwise defective instrument, the registrant may offer to repair such instrument on a flat-rate basis, with at least a 30-day written guarantee that the instrument shall operate properly, except for subsequent damage caused by the customer. If the customer accepts repair on a flat-rate basis, the itemized statement as to the repairs made need not set forth the specific charges therefor.

(e) When a hearing aid is brought in for repair or service, the registrant may supply a suitable loan of an instrument to the consumer for the period the instrument is being repaired or serviced. If such a loaner is available and there is a charge therefor, the customer shall not be required to accept any such loaner as a condition to the repair or service.
