Effective January 12, 2015, equipment approval will not be granted for auditory assistance devices that operate in the 72.0-73.0 MHz, 74.6-74.8 MHz, and 75.2-76.0 MHz bands that do not comply with the requirements of § 15.237(c). These rules do not prohibit the sale or use of authorized auditory assistance devices that operate in the 72.0-73.0 MHz, 74.6-74.8 MHz, and 75.2-76.0 MHz bands manufactured in the United States, or imported into the United States, prior to July 11, 2016.
(h) Effective June 2, 2015 devices using digital modulation techniques in the 5725-5850 MHz bands will no longer be certified under the provisions of § 15.247. The technical requirements for obtaining certification after this date for digitally modulated devices and the digitally modulated portion of hybrid devices are found in subpart E of this part. The provisions for the frequency hopping spread spectrum portion of hybrid devices will remain in § 15.247. Effective June 2, 2016 systems using digital modulation techniques in the 5725-5850 MHz band certified under the provisions of § 15.247 may no longer be imported or marketed within the United States.
