Sec. 1194.25  Self contained, closed products.

    (a) Self contained products shall be usable by people with 
disabilities without requiring an end-user to attach assistive 
technology to the product. Personal headsets for private listening are 
not assistive technology.
    (b) When a timed response is required, the user shall be alerted and 
given sufficient time to indicate more time is required.
    (c) Where a product utilizes touchscreens or contact-sensitive 
controls, an input method shall be provided that complies with 
Sec. 1194.23 (k) (1) through (4).
    (d) When biometric forms of user identification or control are used, 
an alternative form of identification or activation, which does not 
require the user to possess particular biological characteristics, shall 
also be provided.
    (e) When products provide auditory output, the audio signal shall be 
provided at a standard signal level through an industry standard 
connector that will allow for private listening. The product must 
provide the ability to interrupt, pause, and restart the audio at 
anytime.
    (f) When products deliver voice output in a public area, incremental 
volume control shall be provided with output amplification up to a level 
of at least 65 dB. Where the ambient noise level of the environment is 
above 45 dB, a volume gain of at least 20 dB above the ambient level 
shall be user selectable. A function shall be provided to automatically 
reset the volume to the default level after every use.
    (g) Color coding shall not be used as the only means of conveying 
information, indicating an action, prompting a response, or 
distinguishing a visual element.
    (h) When a product permits a user to adjust color and contrast 
settings, a range of color selections capable of producing a variety of 
contrast levels shall be provided.
    (i) Products shall be designed to avoid causing the screen to 
flicker with a frequency greater than 2 Hz and lower than 55 Hz.
    (j) Products which are freestanding, non-portable, and intended to 
be used in one location and which have operable controls shall comply 
with the following:
    (1) The position of any operable control shall be determined with 
respect to a vertical plane, which is 48 inches in length, centered on 
the operable control, and at the maximum protrusion of the product 
within the 48 inch length (see Figure 1 of this part).

[[Page 536]]

    (2) Where any operable control is 10 inches or less behind the 
reference plane, the height shall be 54 inches maximum and 15 inches 
minimum above the floor.
    (3) Where any operable control is more than 10 inches and not more 
than 24 inches behind the reference plane, the height shall be 46 inches 
maximum and 15 inches minimum above the floor.
    (4) Operable controls shall not be more than 24 inches behind the 
reference plane (see Figure 2 of this part).
