Prince William County, Manassas and Manassas Park will use AVC Edge machines.

Voters will use them at all five Manassas polls and at Manassas Park's one poll.

Prince William will provide at least two touch-screen voting units at each of its 62 polling sites, and voters may use them if they wish.

What's the first step?

Indicate you want to use the machine, and a poll worker will activate the machine, providing a new electronic ballot on the screen.

How do I vote?

Candidates' names appear on the screen. Make selections by touching a fingertip to the circle to the right of the candidate's name. A check mark appears.

Can I change my vote?

Yes, just touch the circle again and the check mark disappears. Make another choice.

Can I write in a choice?

Touch "Write In" and a touch-screen keyboard appears. Use it to enter the full name of the person you wish to vote for.

How do I move on to other offices?

Touch the "Done" arrow in the lower right corner of the screen and advance to the next screen.

What if I don't want to vote for every office?

The machine will allow under voting, but you'll be warned that you under voted. You can review and modify the ballot by touching the "Review" button.

What if I get confused and vote for more candidates than I should have?

The machine will not allow that. Once the maximum allowable selections have been made, the voting circles disappear beside the other names or choices not selected.

How do I look back to see who I have voted for?

Use the yellow "Next" and "Back" arrows to move among screens. Touch "Review" at any time to see all your choices on one screen.

How do I finally cast my vote?

Touch the yellow "Cast Vote" button in the middle of the screen.

Special features:

Machines are accessible to people with disabilities. A device can be plugged into the unit that allows voting by the visually impaired.
