The Reader/Writer has a self-diagnostic function to check a variety of items in order to reduce the
downtime of the system that may result due to operational failures.
Details of Errors

“nonfatal errors.”
Fatal error If the hardware of the Reader/Writer fails, the operation of the CPU will be
interrupted and the ERROR indicator will turn ON or flash.
