   packaging a statement that the ACS telephonic CPE is not hearing aid
   compatible, as defined in § § 68.4(a)(3), 68.316, 68.317, or if offered
   for sale without a surrounding package, shall be affixed with a written
   statement that the telephone is not hearing aid compatible, as defined
   in § § 68.4(a)(3), 68.316 and 68.317; and be accompanied by instructions
