Haw. Code R. § 3-177-756
Prior to election day, the chief election officer, county clerk, or designees shall test the electronic voting system. If, as a result of the initial testing, the chief election officer determines additional inspection, auditing or testing is required, the chief election officer shall notify the official observers so that they can witness the additional inspection, auditing or retesting needed to ensure that the voting system is working properly. If, after election day, the post-election, pre-certification audit indicates misreporting within the system, the chief election officer shall notify the official observers so that they can witness the additional inspection, auditing or retesting performed to ascertain the nature of the problem.
