721—22.500 (52) Blended systems. When the commissioner orders the use of precinct count optical scan and direct recording electronic voting machines in the same precinct, both components of the blended system shall be certified as part of the same voting system.
	 22.500(1) Accessible device. At least one of the two components shall be accessible to persons with disabilities. However, any voter may use the accessible device whether or not the person is disabled.
	 22.500(2) Encouraged use. Precinct election officials shall encourage the use of both components to protect the secrecy of all ballots. A single ballot cast on a voting device is not a secret ballot.
	 22.500(3) Combining totals. If the two devices cannot produce a single, combined report of the results of the precinct, the precinct officials shall add the totals from both devices together at the polls on election night. Precinct officials may transmit the totals electronically in a separate report for each device. The commissioner shall combine the totals for each precinct before releasing any unofficial reports.
