Maintenance Reset
For security purposes, the device is designed to perform an automatic maintenance reset periodically to
clear all data from memory. When the device has been on continuously for 23 hours, it stops responding
to new commands, shows
Maintenance Reset…
on the display, and performs a full reset. If a
transaction is pending, the device waits a reasonable period of time for the transaction to complete before
resetting. At the end of the automatic maintenance reset, the device powers back on and return to normal
operation.
