36 CFR Part 1193 Telecommunications Act (Section 255) Accessibility Guidelines

Paragraph (g)

Operable without Time-Dependent Controls

1. Many persons find it very difficult to operate time-dependent controls.

2. Some strategies which address this problem include:

a. Avoid any timed-out situations or provide instances where the user must respond to a question or moving display in a set amount of time or at a specific time (e.g., a rotating display).

b. Where timed responses are required or appropriate, allow the user to adjust them or set the amount of time allotted to complete a given task. Warn users that time is running out and allow them to secure extended time.

c. If the standard mode of operation would be awkward or inefficient, then provide an alternate mode of operation that offers the same functions.
