For the instruction of the voters on election day, there shall be provided for each polling place, one mechanically operated instruction model for each machine, showing a portion of the face of the voting machine. Each such instruction model shall show the arrangement of party rows, office columns and questions, but only fictitious candidates' names shall be used. Such model shall be located on the election officials' table, or in some other place which the voters must pass to reach the machine, and each voter, upon request, before entering the machine, shall be offered instruction in its operation by use of the instruction model, and the voter shall be given ample opportunity to operate the model himself. Each voter shall also have called to his attention the facsimile diagrams at least two of which shall be posted on the walls of the polling place, which facsimile diagrams shall be exact facsimiles, including the color of the ballot labels, as near as may be, of the face of the voting machine, so that the voter can become familiar with the location of the questions, parties, officers and candidates. In case any voter after entering the voting machine booth shall ask for further instructions concerning the manner of voting, two judges of opposite political parties shall give such instructions to him; but no precinct election official, or person assisting a voter shall in any manner request, suggest or seek to persuade, or induce any voter to vote any particular ticket, or for any particular candidate, or for or against any particular amendment, question or proposition. During such instruction, the curtains shall be thrown aside so that the instruction may be observed by persons in the polling place. After giving such instructions such precinct election officials shall retire from the machine booth, and the voter shall thereafter, with the curtains closed around him, proceed to vote as in the case of an unassisted voter.
