New Jersey Statutes Title 19. Elections 19 § 50-2

a. For the first four successive general elections after the adoption of a new type of voting machine in a county, the county board of elections or the superintendent of elections , as the case may be, having custody of voting machines, shall designate suitable and adequate times and places where voting machines containing sample ballots showing titles of offices to be filled, and, so far as practicable, the names of candidates to be voted for at the next election, shall be exhibited for the purpose of giving instructions in the use of voting machines . No voting machine to be assigned for use in an election shall be used for such instruction after having been prepared and sealed for the election. During public exhibition of any voting machine for the instruction of voters previous to an election, the counting mechanism thereof shall be concealed from view and the doors may be temporarily opened only when authorized by such county board of elections or such superintendent of elections or such municipal clerk, as the case may be.

b. The county board of elections shall design, prepare and make available to voters instructions on the proper operation of the voting machine used in the county. The instructions may be conveyed on cards, computer software, pamphlets, posters, video or such other media as the county board deems appropriate, subject to the guidelines set forth by the Attorney General. The instructions shall also be made available on the official Internet site of the Division of Elections in the Department of Law and Public Safety and the county board of elections shall provide a link to such instructions on its official Internet site. The Attorney General shall establish guidelines for the design of instructions for the proper operation of voting machines used in this State. The provisions of this subsection shall be in addition to any other provision for voter instruction required by law.
