(c)Voice mail, auto-attendant, and interactive voice response telecommunications systems shall be usable by TTY users with their TTYs. (d)Voice mail, messaging, auto-attendant, and interactive voice response telecommunications systems that require a response from a user within a time interval, shall give an alert when the time interval is about to run out, and shall provide sufficient time for the user to indicate more time is required. (e)Where provided, caller identification and similar telecommunications functions shall also be available for users of TTYs, and for users who cannot see displays. (f)For transmitted voice signals, telecommunications products shall provide a gain adjustable up to a minimum of 20 dB.

(g)If the telecommunications product allows a user to adjust the receive volume, a function shall be provided to automatically reset the volume to the default level after every use. (h)Where a telecommunications product delivers output by an audio transducer which is normally held up to the ear, a means for effective magnetic wireless coupling to hearing technologies shall be provided. (i)Interference to hearing technologies (including hearing aids, cochlear implants, and assistive listening devices) shall be reduced to the lowest possible level that allows a user of hearing technologies to utilize the telecommunications product. (j)Products that transmit or conduct information or communication, shall pass through cross-manufacturer, non-proprietary, industry-standard codes, translation protocols, formats or other information necessary to provide the information or communication in a usable format. Technologies which use encoding, signal compression, format transformation, or similar techniques shall not remove information needed for access or shall restore it upon delivery. (k)Products which have mechanically operated controls or keys, shall comply with the following: (1)Controls and keys shall be tactilely discernible without activating the controls or keys. (2)Controls and keys shall be operable with one hand and shall not require tight grasping, pinching, or twisting of the wrist. The force required to activate controls and keys shall be 5 lbs. (22.2 N) maximum. (3)If key repeat is supported, the delay before repeat shall be adjustable to at least 2 seconds. Key repeat rate shall be adjustable to 2 seconds per character. (4)The status of all locking or toggle controls or keys shall be visually discernible, and discernible either through touch or sound.
