An activation card is required for use, which is provided by a poll worker. The machine has audio capability for up to ten languages, as required by the U.S. Department of Justice, and includes a 19" full-color screen for visual operation, audio and visual marking interfaces and Audio-Tactile Interface (ATI). ATI is a hand-held controller that coordinates with headphones and connects directly to the ICE. During the voting process, the machine generates a marked paper ballot that serves as the official ballot record. The display can be adjusted with contrast and zoom functions that automatically reset at the end of the session. The ATI device has raised keys with tactile function, includes the headphone jack and a T-coil coupling, and has a T4 rating for interference. It uses light pressure switches and may be equipped with a pneumatic switch, commonly known as "sip-n-puff", or a set of paddles. ImageCast Central uses commercial off-the-shelf Canon DR-X10C or Canon DR-G1130 scanners at a central tabulation location to scan vote-by-mail and post-voting ballots like provisional ballots, ballots requiring duplication and ballots scanned into multi-precinct ICE tabulators. The results are dropped into a folder located on the server where they can be accessed by the Adjudication Client software. Software DVS voting machines operate using a suite of proprietary software applications, including Election Management System, Adjudication Client, and Mobile Ballot Printing. The software allows for various settings, including cumulative voting, where voters can apply multiple votes on one or more candidates, and Ranked Order Voting, where voters rank candidates in order of choice and the system shifts votes as candidates are eliminated. The Election Management System (EMS) includes a set of applications that handle pre- and post-voting activities, including ballot layout, programming media for voting equipment, generation of audio files, importing results data, and accumulating and reporting results. Adjudication Client is a software application with administrative and ballot inspection roles. It allows a jurisdiction to resolve problems in a ballot on screen that would normally be rejected, to be remade or hand counted because of one or more exceptional conditions like a blank ballot, write-ins, over-votes, marginal marks and under-votes. The application configures user accounts, reasons for exception, batch management and report generation, which in some jurisdictions must be performed by an administrator directly on a server. Ballot inspection allows users to review ballots with exceptional conditions and either accept or resolve the ballot according
