   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) Website and record retention requirements. (1) Each manufacturer
   and service provider that operates a publicly-accessible website must
   make available on its website 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 website, based on the levels of functionality and rating
   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. Each
   service provider must also include on its website: A list of all
   non-hearing aid-compatible models currently offered, including the
   level of functionality that each of those models falls under, an
   explanation of how the functionality of the handsets varies at the
   different levels as well as a link to the current FCC web page
   containing information about the wireless hearing aid compatibility
   rules and service providers' obligations. Each service provider must
   also include the marketing model name/number(s) and FCC ID number of
   each hearing aid-compatible and non-hearing aid-compatible model
   currently offered.

   (2) Service providers must maintain on their website either:

   (i) A link to a third-party website as designated by the Commission or
   Wireless Telecommunications Bureau with information regarding hearing
   aid-compatible and non-hearing aid-compatible handset models; or

   (ii) A clearly marked list of hearing aid-compatible handset models
   that are no longer offered if the calendar month/year that model was
   last offered is within 24 months of the current calendar month/year and
   was last offered in January 2018 or later along with the information
   listed in paragraph (h)(1) of this section for each hearing
   aid-compatible handset.

   (3) If the Wireless Telecommunications Bureau determines that the
   third-party website has been eliminated or is not updated in a timely
   manner, it may select another website or require service providers to
   comply with paragraph (h)(2)(ii) of this section.

   (4) The information on the website must be updated within 30 days of
   any relevant changes, and any website pages containing information so
   updated must indicate the day on which the update occurred.

   (5) Service providers must maintain internal records including the
   ratings, if applicable, of all hearing aid-compatible and non-hearing
   aid-compatible models no longer offered (if the calendar month/year
   that model was last offered is within 24 months of the current calendar
   month/year and was last offered in January 2018 or later); for models
   no longer offered (if the calendar month/year that model was last
   offered is within 24 months of the current calendar month/year), the
   calendar months and years each hearing aid-compatible and non-hearing
   aid-compatible model was first and last offered; and the marketing
   model name/number(s) and FCC ID number of each hearing aid-compatible
   and non-hearing aid-compatible model no longer offered (if the calendar
   month/year that model was last offered is within 24 months of the
   current calendar month/year and was last offered in January 2018 or
   later).

   (i) Reporting requirements--(1) Reporting and certification dates.
   Manufacturers shall submit reports on efforts toward compliance with
   the requirements of this section on an annual basis on July 15. Service

   (vi) The following language:

   I am a knowledgeable executive [of company x] regarding compliance with
   the Federal Communications Commission's wireless hearing aid
   compatibility requirements at a wireless service provider covered by
   those requirements.

   I certify that the provider was [(in full compliance/not in full
   compliance)] [choose one] at all times during the applicable time
   period with the Commission's wireless hearing aid compatibility
   deployment benchmarks and all other relevant wireless hearing aid
   compatibility requirements.

   The company represents and warrants, and I certify by this declaration
   under penalty of perjury pursuant to 47 CFR 1.16 that the above
   certification is consistent with 47 CFR 1.17, which requires truthful
   and accurate statements to the Commission. The company also
   acknowledges that false statements and misrepresentations to the
   Commission are punishable under Title 18 of the U.S. Code and may
   subject it to enforcement action pursuant to Sections 501 and 503 of
   the Act.

   (vii) If the company selected that it was not in full compliance, an
   explanation of which wireless hearing aid compatibility requirements it

   authority to approve or prescribe formats and methods for submission of
   the reports and certifications required by this section. Any format
   that the Bureau may approve or prescribe shall be made available on the
   Bureau's website.

   (j) Enforcement. Enforcement of this section is hereby delegated to
   those states that adopt this section and provide for enforcement. The
   procedures followed by a state to enforce this section shall provide a
   30-day period after a complaint is filed, during which time state
   personnel shall attempt to resolve a dispute on an informal basis. If a
   state has not adopted or incorporated this section, or failed to act
   within six (6) months from the filing of a complaint with the state
   public utility commission, the Commission will accept such complaints.
   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, inductive coupling, or volume control
   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 standards 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 the technical standards
   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. All approved
   material is available for inspection at the Federal Communications
   Commission (FCC), 445 12th St. SW, Reference Information Center, Room
