B.1 Error Messages Introduction
This appendix lists the Integrated Access System error messages. One of these messages may

not perform the requested action. This condition may have been caused by an operator error,
absence of a card in the system, or other condition. If an error message appears, take the
appropriate corrective action. For convenience, the system error messages are listed
alphabetically.
