The Spyrus unit automatically shuts down after a 90 second idle period. This time was in the calculations already presented below (see low power for 90 seconds.) I'd just let the Spyrus do its own power down and not add to the pollworkers' confusion.

What do you see as the best election day procedure for pollworkers? Don Donald W. Biszmaier Support Services Specialist Diebold Election Systems, Inc. 7717 Greenwood Rd.

Sitting on the Shelf The Spyrus units lose battery power just sitting on the shelf. After installing a fresh set of batteries, it would take approx. one year before they died. Operation Scenario On a fresh set of batteries, and based on the operation model noted below, the Spyrus can program approx. 1300 smart cards before needing another fresh set of batteries. Operation model: Assumed each operation takes 2 minutes, and during the two minutes operation, the smart card is powered on for 20 seconds. During the 2 minutes operation, the PAR2 is running at full power for 30 seconds, and low power for 90 seconds. When the PAR2 is waiting for a key input, or processing a command from the Diebold application, it would be running in the low power mode. As an example, t aking both power consumption factors into account, a Spyrus unit never used after fresh batteries were installed and sitting on a shelf for 6 months would have 50% battery power left. It would therefore be able to program approx. 650 smart cards (half of the 1300.) Sincerely: Ian S. Piper Diebold Election Systems, Inc. 972.542.6000
