§  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
   800-950 MHz or 1.6-2.5 GHz bands using any air interface for which
   technical standards are stated in the standard document "American
   National Standard Methods of Measurement of Compatibility Between
   Wireless Communication Devices and Hearing Aids," American National
   Standards Institute (ANSI) C63.19-2007 (June 8, 2007).

   (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. A wireless handset
   used for digital CMRS only over the frequency bands and air interfaces
   referenced in paragraph (a)(1) of this section is hearing
   aid-compatible with regard to radio frequency interference or inductive
   coupling if it meets the applicable technical standard(s) set forth in
   paragraphs (b)(1) and (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 an air interface or operates over a frequency band
   for which no technical standards are stated in ANSI C63.19-2007 (June
   8, 2007) is hearing aid-compatible if the handset otherwise satisfies
   the requirements of this paragraph.

   (1) For radio frequency interference.

   (i) Applicable technical standards prior to 2010. Beginning June 6,
   2008 and until January 1, 2010, 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
   C63.19-2006 (June 12, 2006) or ANSI C63.19-2007 (June 8, 2007)--each
   available for purchase from the American National Standards Institute.
   Any grants of certification issued before June 6, 2008 under previous
   versions of ANSI C63.19 remain valid for hearing aid compatibility
   purposes.

   (ii) Applicable technical standards beginning in 2010. On or after
   January 1, 2010, 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 ANSI C63.19-2007 (June 8, 2007).
   Any grants of certification issued before January 1, 2010, under the
   earlier versions of ANSI C63.19 remain valid for hearing aid
   compatibility purposes.

   (2) For inductive coupling.

   (i) Applicable technical standards prior to 2010. Beginning June 6,
   2008 and until January 1, 2010, 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
   C63.19-2006 (June 12, 2006) or ANSI C63.19-2007 (June 8, 2007). Any
   grants of certification issued before June 6, 2008 under previous
   versions of ANSI C63.19 remain valid for hearing aid compatibility
   purposes.

   (ii) Applicable technical standards beginning in 2010. On or after
   January 1, 2010, 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 ANSI C63.19-2007 (June 8, 2007).

   paragraphs (b)(1) and (b)(2) of this section.

   (f) Labeling and disclosure requirements. (1) Labeling requirements.
   Manufacturers and service providers shall ensure that handsets that are
   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)(i) Disclosure requirement relating to handsets that operate over an
   air interface or frequency band without hearing aid compatibility
   technical standards. Each manufacturer and service provider shall
   ensure that, wherever it provides hearing aid compatibility ratings for
   a handset that incorporates an air interface or operates over a
   frequency band for which no technical standards are stated in ANSI
   C63.19-2007 (June 8, 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 has not been rated for hearing aid
   compatibility with respect to that operation. 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.

   (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

   address of the page(s) containing the information regarding hearing
   aid-compatible handset models required by paragraph (h) of this
   section.

   Note to paragraph (i)(3): For reports due on January 15, 2009,
   information provided with respect to paragraphs (i)(3)(i) through
   (i)(3)(iv) and (i)(3)(vi) through (i)(3)(viii) need be provided only
   for the six-month period from July 1 to December 31, 2008.

   (4) Format. The Wireless Telecommunications Bureau is delegated
   authority to approve or prescribe formats and methods for submission of
   these reports. Any format that the Bureau may approve or prescribe
   shall be made available on the Bureau's Web site.

   (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. --(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 C63^TM,
   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.
