§ 14.21 Performance Objectives.
(a) Generally. Manufacturers and service providers shall ensure that
equipment and services covered by this part are accessible, usable, and
compatible as those terms are defined in paragraphs (b) through (d) of
(b) Accessible. The term accessible shall mean that:
(1) Input, control, and mechanical functions shall be locatable,
identifiable, and operable in accordance with each of the following,
(i) Operable without vision. Provide at least one mode that does not
require user vision.
(ii) Operable with low vision and limited or no hearing. Provide at
least one mode that permits operation by users with visual acuity
between 20/70 and 20/200, without relying on audio output.
(iii) Operable with little or no color perception. Provide at least one
mode that does not require user color perception.
(iv) Operable without hearing. Provide at least one mode that does not
require user auditory perception.
(v) Operable with limited manual dexterity. Provide at least one mode
that does not require user fine motor control or simultaneous actions.
(vi) Operable with limited reach and strength. Provide at least one
mode that is operable with user limited reach and strength.
(vii) Operable with a Prosthetic Device. Controls shall be operable
without requiring body contact or close body proximity.
(viii) Operable without time-dependent controls. Provide at least one
mode that does not require a response time or allows response time to
be by-passed or adjusted by the user over a wide range.
(ix) Operable without speech. Provide at least one mode that does not
require user speech.
(x) Operable with limited cognitive skills. Provide at least one mode
that minimizes the cognitive, memory, language, and learning skills
required of the user.
(2) All information necessary to operate and use the product, including
but not limited to, text, static or dynamic images, icons, labels,
sounds, or incidental operating cues, [shall] comply with each of the
following, assessed independently:
(i) Availability of visual information. Provide visual information
through at least one mode in auditory form.
(ii) Availability of visual information for low vision users. Provide
visual information through at least one mode to users with visual
acuity between 20/70 and 20/200 without relying on audio.
(iii) Access to moving text. Provide moving text in at least one static
presentation mode at the option of the user.
(iv) Availability of auditory information. Provide auditory information
through at least one mode in visual form and, where appropriate, in
(v) Availability of auditory information for people who are hard of
hearing. Provide audio or acoustic information, including any auditory
feedback tones that are important for the use of the product, through
at least one mode in enhanced auditory fashion (i.e., increased
amplification, increased signal-to-noise ratio, or combination).
(vi) Prevention of visually-induced seizures. Visual displays and
indicators shall minimize visual flicker that might induce seizures in
people with photosensitive epilepsy.
(vii) Availability of audio cutoff. Where a product delivers audio
output through an external speaker, provide an industry standard
connector for headphones or personal listening devices (e.g.,
phone-like handset or earcup) which cuts off the speaker(s) when used.
(viii) Non-interference with hearing technologies. Reduce interference
to hearing technologies (including hearing aids, cochlear implants, and
assistive listening devices) to the lowest possible level that allows a
user to utilize the product.
(ix) Hearing aid coupling. Where a product delivers output by an audio
transducer which is normally held up to the ear, provide a means for
effective wireless coupling to hearing aids.
(3) Real-Time Text. Wireless interconnected VoIP services subject to
this part and text-capable end user devices used with such services
that do not themselves provide TTY functionality, may provide TTY
connectability and signal compatibility pursuant to paragraphs (b)(3)
and (4) of this section, or support real-time text communications, in
accordance with 47 CFR part 67.
(c) Usable. The term usable shall mean that individuals with
disabilities have access to the full functionality and documentation
for the product, including instructions, product information (including
accessible feature information), documentation and technical support
functionally equivalent to that provided to individuals without
(d) Compatible. The term compatible shall mean compatible with
peripheral devices and specialized customer premises equipment, and in
compliance with the following provisions, as applicable:
(1) External electronic access to all information and control
mechanisms. Information needed for the operation of products (including
output, alerts, icons, on-line help, and documentation) shall be
available in a standard electronic text format on a cross-industry
standard port and all input to and control of a product shall allow for
real time operation by electronic text input into a cross-industry
standard external port and in cross-industry standard format. The
cross-industry standard port shall not require manipulation of a
connector by the user.
(2) Connection point for external audio processing devices. Products
providing auditory output shall provide the auditory signal at a
standard signal level through an industry standard connector.
(3) TTY connectability. Products that provide a function allowing voice
communication and which do not themselves provide a TTY functionality
shall provide a standard non-acoustic connection point for TTYs. It
shall also be possible for the user to easily turn any microphone on
and off to allow the user to intermix speech with TTY use.
(4) TTY signal compatibility. Products, including those providing voice
communication functionality, shall support use of all
cross-manufacturer non-proprietary standard signals used by TTYs.
(5) TTY Support Exemption. Interconnected and non-interconnected VoIP
services subject to this part that are provided over wireless IP
facilities and equipment are not required to provide TTY connectability
and TTY signal compatibility if such services and equipment support
real-time text, in accordance with 47 CFR part 67.
