§  20.19   Hearing aid-compatible mobile handsets.

   (a) Scope of section; definitions. (1) The hearing aid compatibility
   requirements of this section apply to providers of digital CMRS in the
   United States to the extent that they offer real-time, two-way switched
   voice or data service that is interconnected with the public switched
   network and utilizes an in-network switching facility that enables the
   provider to reuse frequencies and accomplish seamless hand-offs of
   subscriber calls, and such service is provided over frequencies in the
   698 MHz to 6 GHz bands.

   (2) The requirements of this section also apply to the manufacturers of
   the wireless handsets that are used in delivery of the services
   specified in paragraph (a)(1) of this section.

   (3) Definitions . For purposes of this section:

   (i) Handset refers to a device used in delivery of the services
   specified in paragraph (a)(1) of this section that contains a built-in
   speaker and is typically held to the ear in any of its ordinary uses.

   (ii) Manufacturer refers to a wireless handset manufacturer to which
   the requirements of this section apply.

   (iii) Model refers to a wireless handset device that a manufacturer has
   designated as a distinct device model, consistent with its own
   marketing practices. However, if a manufacturer assigns different model
   device designations solely to distinguish units sold to different
   carriers, or to signify other distinctions that do not relate to either
   form, features, or capabilities, such designations shall not count as
   distinct models for purposes of this section.

   (iv) Service provider refers to a provider of digital CMRS to which the
   requirements of this section apply.

   (v) Tier I carrier refers to a CMRS provider that offers such service
   nationwide.

   (b) Hearing aid compatibility; technical standards —(1) For radio
   frequency interference. A wireless handset submitted for equipment
   certification or for a permissive change relating to hearing aid
   compatibility must meet, at a minimum, the M3 rating associated with
   the technical standard set forth in either the standard document
   “American National Standard Methods of Measurement of Compatibility
   Between Wireless Communication Devices and Hearing Aids,” ANSI
   C63.19-2007 or ANSI C63.19-2011. Any grants of certification issued
   before January 1, 2010, under previous versions of ANSI C63.19 remain
   valid for hearing aid compatibility purposes.

   (2) For inductive coupling. A wireless handset submitted for equipment
   certification or for a permissive change relating to hearing aid
   compatibility must meet, at a minimum, the T3 rating associated with
   the technical standard set forth in either the standard document
   “American National Standard Methods of Measurement of Compatibility
   Between Wireless Communication Devices and Hearing Aids,” ANSI
   C63.19-2007 or ANSI C63.19-2011. Any grants of certification issued
   before January 1, 2010, under previous versions of ANSI C63.19 remain
   valid for hearing aid compatibility purposes.

   (3) Handsets operating over multiple frequency bands or air interfaces.
   (i) Except as provided in paragraph (b)(3)(ii) of this section, a
   wireless handset used for digital CMRS only over the 698 MHz to 6 GHz
   frequency bands is hearing aid-compatible with regard to radio
   frequency interference or inductive coupling if it meets the applicable
   technical standard set forth in paragraph (b)(1) or (b)(2) of this
   section for all frequency bands and air interfaces over which it
   operates, and the handset has been certified as compliant with the test
   requirements for the applicable standard pursuant to §  2.1033(d) of
   this chapter. A wireless handset that incorporates operations outside
   the 698 MHz to 6 GHz frequency bands is hearing aid-compatible if the
   handset otherwise satisfies the requirements of this paragraph.

   (ii) A handset that is introduced by the manufacturer prior to July 17,
   2013, and that does not meet the requirements for hearing aid
   compatibility under paragraph (b)(3)(i) of this section, is hearing
   aid-compatible for radio frequency interference or inductive coupling
   only with respect to those frequency bands and air interfaces for which
   technical standards are stated in ANSI C63.19-2007 if it meets, at a
   minimum, an M3 rating (for radio frequency interference) or a T3 rating
   (for inductive coupling) under ANSI C63.19-2007 for all such frequency
   bands and air interfaces over which it operates, and the handset has
   been certified as compliant with the test requirements for the
   applicable standard pursuant to §  2.1033(d) of this chapter.

   (4) All factual questions of whether a wireless handset meets the
   technical standard(s) of this paragraph shall be referred for
   resolution to the Chief, Office of Engineering and Technology, Federal
   Communications Commission, 445 12th Street, SW., Washington, DC 20554.

   hearing aid-compatible, as defined in paragraph (b) of this section,
   clearly display the rating, as defined in paragraphs (b)(1) and (b)(2)
   of this section, on the packaging material of the handset. In the event
   that a hearing aid-compatible handset achieves different radio
   interference or inductive coupling ratings over different air
   interfaces or different frequency bands, the RF interference reduction
   and inductive coupling capability ratings displayed shall be the lowest
   rating assigned to that handset for any air interface or frequency
   band. An explanation of the ANSI C63.19 rating system must also be
   included in the device's user's manual or as an insert in the packaging
   material for the handset.

   (2) Disclosure requirements relating to handsets treated as hearing
   aid-compatible over fewer than all their operations.

   (i) Each manufacturer and service provider shall ensure that, wherever
   it provides hearing aid compatibility ratings for a handset that is
   considered hearing aid-compatible under paragraph (b)(3)(ii) of this
   section only with respect to those frequency bands and air interfaces
   for which technical standards are stated in ANSI C63.19-2007 and that
   has not been tested for hearing aid compatibility under ANSI
   C63.19-2011, or any handset that operates over frequencies outside of
   the 698 MHz to 6 GHz bands, it discloses to consumers, by clear and
   effective means (e.g., inclusion of call-out cards or other media,
   revisions to packaging materials, supplying of information on Web
   sites), that the handset has not been rated for hearing aid
   compatibility with respect to some of its operation(s). This disclosure
   shall include the following language:

   This phone has been tested and rated for use with hearing aids for some
   of the wireless technologies that it uses. However, there may be some
   newer wireless technologies used in this phone that have not been
   tested yet for use with hearing aids. It is important to try the
   different features of this phone thoroughly and in different locations,
   using your hearing aid or cochlear implant, to determine if you hear
   any interfering noise. Consult your service provider or the
   manufacturer of this phone for information on hearing aid
   compatibility. If you have questions about return or exchange policies,
   consult your service provider or phone retailer.

   (ii) However, service providers are not required to include this
   language in the packaging material for handsets that incorporate a
   Wi-Fi air interface and that were obtained by the service provider
   before March 8, 2011, provided that the service provider otherwise
   discloses by clear and effective means that the handset has not been
   rated for hearing aid compatibility with respect to Wi-Fi operation.

   (iii) Each manufacturer and service provider shall ensure that,
   wherever it provides hearing aid compatibility ratings for a handset
   that is considered hearing aid-compatible under paragraph (b)(3)(ii) of
   this section only with respect to those frequency bands and air
   interfaces for which technical standards are stated in ANSI
   C63.19-2007, and that the manufacturer has tested and found not to meet
   hearing aid compatibility requirements under ANSI C63.19-2011 for
   operations over one or more air interfaces or frequency bands for which
   technical standards are not stated in ANSI C63.19-2007, it discloses to
   consumers, by clear and effective means (e.g., inclusion of call-out
   cards or other media, revisions to packaging materials, supplying of
   information on Web sites), that the handset does not meet the relevant
   rating or ratings with respect to such operation(s).

   (3) Disclosure requirement relating to handsets that allow the user to
   reduce the maximum power for GSM operation in the 1900 MHz band.
   Handsets offered to satisfy paragraph (e)(1)(iii) of this section shall
   be labeled as meeting an M3 rating. Each manufacturer and service
   provider shall ensure that, wherever this rating is displayed, it
   discloses to consumers, by clear and effective means ( e.g., inclusion
   of call-out cards or other media, revisions to packaging materials,
   supplying of information on Web sites), that user activation of a
   special mode is necessary to meet the hearing aid compatibility
   standard. In addition, each manufacturer or service provider shall
   ensure that the device manual or a product insert explains how to
   activate the special mode and that doing so may result in a reduction
   of coverage.

   (g) Model designation requirements. Where a manufacturer has made
   physical changes to a handset that result in a change in the hearing
   aid compatibility rating under paragraph (b)(1) or (b)(2) of this
   section, the altered handset must be given a model designation distinct
   from that of the handset prior to its alteration.

   (h) Web site requirements. Beginning January 15, 2009, each
   manufacturer and service provider subject to this section that operates
   a publicly-accessible Web site must make available on its Web site a
   list of all hearing aid-compatible models currently offered, the
   ratings of those models, and an explanation of the rating system. Each
   service provider must also specify on its Web site, based on the levels
   of functionality that the service provider has defined, the level that
   each hearing aid-compatible model falls under as well as an explanation
   of how the functionality of the handsets varies at the different
   levels.

   (i) Reporting requirements —(1) Reporting dates. Manufacturers shall

   A written notification to the complainant that the state believes
   action is unwarranted is not a failure to act. The procedures set forth
   in part 68, subpart E of this chapter are to be followed.

   (k) Delegation of rulemaking authority. (1) The Chief of the Wireless
   Telecommunications Bureau and the Chief of the Office of Engineering
   and Technology are delegated authority, by notice-and-comment
   rulemaking, to issue an order amending this section to the extent
   necessary to adopt technical standards for additional frequency bands
   and/or air interfaces upon the establishment of such standards by ANSI
   Accredited Standards Committee C63TM , provided that the standards do
   not impose with respect to such frequency bands or air interfaces
   materially greater obligations than those imposed on other services
   subject to this section. Any new obligations on manufacturers and Tier
   I carriers pursuant to paragraphs (c) through (i) of this section as a
   result of such standards shall become effective no less than one year
   after release of the order adopting such standards and any new
   obligations on other service providers shall become effective no less
   than 15 months after the release of such order, except that any new
   obligations on manufacturers and service providers subject to paragraph
   (e)(1)(ii) of this section shall become effective no less than two
   years after the release of such order.

   (2) The Chief of the Wireless Telecommunications Bureau and the Chief
   of the Office of Engineering and Technology are delegated authority, by
   notice-and-comment rulemaking if required by statute or otherwise in
   the public interest, to issue an order amending this section to the
   extent necessary to approve any version of the technical standards for
   radio frequency interference or inductive coupling adopted subsequently
   to ANSI C63.19-2007 for use in determining whether a wireless handset
   meets the appropriate rating over frequency bands and air interfaces
   for which technical standards have previously been adopted either by
   the Commission or pursuant to paragraph (k)(1) of this section. This
   delegation is limited to the approval of changes to the technical
   standard that do not raise major compliance issues. Further, by such
   approvals, the Chiefs may only permit, and not require, the use of such
   subsequent versions of standard document ANSI C63.19 to establish
   hearing aid compatibility.

   (l) The standards required in this section are incorporated by
   reference into this section with the approval of the Director of the
   Federal Register under 5 U.S.C. 552(a) and 1 CFR part 51. To enforce
   any edition other than those specified in this section, the FCC must
   publish notice of change in the   Federal Register   and the material
   must be available to the public. All approved material is available for
   inspection at the Federal Communications Commission (FCC), 445 12th St.
   SW., Reference Information Center, Room CY-A257, Washington, DC 20554
   and is available from the sources indicated below. It is also available
   for inspection at the National Archives and Records Administration
   (NARA). For information on the availability of this material at NARA,
