The election authority shall provide at least 4 facsimile diagrams which shall be arranged in the form of a diagram showing the entire front of the voting machine as it will appear after the official ballot labels are arranged for voting purposes on election day. Where colored ballot labels are required to be used, the facsimile diagrams shall be appropriately colored to indicate such ballot labels. Such diagrams shall be displayed for public inspection, 2 on the outside of the polling place, and 2 on the inside thereof, at such polling place during the day preceding election or primary day and throughout election day. At each election where voting machines are to be used, the election authority shall, not less than 10 days before the election, provide for each election precinct in which a voting machine is to be used, facsimile diagrams, printed on tinted paper, in an amount equal to at least 1/5 of the number of votes cast in such precinct at the last preceding general election. Such facsimile diagrams shall be made available for public distribution except that ten per cent (10%) of the number of the ballots printed shall be supplied to the judges of election on election day for use in instructing the voters and for distribution to the voters by them in their discretion. Such facsimile diagrams may be of reduced size and shall provide complete instructions for operating the voting machine in that election.
