Microvote MV-464

The Microvote MV-464 is a Direct Recording Electronic (DRE) voting machine. This article generally describes the specific MV-464 model.

Voter verification
The MV-464 does NOT have a federally-qualified voter-verified paper audit trail capability.

Brief description
This model is no longer in production.

Detailed Voting Process
The voter makes each candidate selection by pressing the gray button beside a candidate’s name. This turns a light on next to the button. To change a selection, a voter presses the gray button a second time, and the light turns off.

The voter may navigate forward through ballot screens by pressing the green “Advance Ballot” bar at the bottom of the panel. The voter may navigate back through ballot screens by pressing the blue “Review Ballot” bar at the bottom of the panel. The voter must view all pages of the ballot before the machine will allow a vote to be case.

To cast a write-in vote, the voter presses the gray write-in selection button on the bottom left side of the panel. The light next to it will start blinking. The voter then writes in the desired name on the paper tape in the write-in window, also at the bottom left of the panel. The voter may change his or her mind by pressing the same write-in button again to turn out the light, and then vote as usual.

To cast the ballot, the voter presses the red “Cast Vote” button on the bottom right side of the panel.

Pre-2008 election

 * November 1995, January 1996: Pennsylvania - The DREs shut-down haphazardly, causing the current voter's vote to be lost. The scroll motors emitted power surges that caused the machines to go into power-fail mode and shut down to protect the circuitry. Accumulation software malfunctioned reported incorrect unofficial results.


 * July 1998: North Carolina - The DREs shut-down haphazardly, causing the current voter's vote to be lost. The scroll motors emitted power surges that caused the machines to go into power-fail mode and shut down to protect the circuitry. 2


 * November 2003: Indiana – Electronic vote-tabulation equipment reported that 140,000 votes had been cast in a county of 50,000 residents.
