§ 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 submit
reports on efforts toward compliance with the requirements of this section
on January 15, 2009 and on July 15, 2009, and on an annual basis on July 15

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
