In case any voter after entering the voting machine asks for further instructions concerning the manner of voting, a judge shall give such instruction to him; but no judge or other election officer or person assisting such voter shall enter the voting machine, except as provided in section 31-10-608 , or in any manner request, suggest, or seek to persuade or induce any such voter to vote for any particular ticket, or for any particular candidate, or for or against any particular amendment, question, or proposition. After receiving such instruction, such voter shall vote as in the case of an unassisted voter.
