exceptions are power supply problems and display malfunctions. The FSC can
be used to determine a recovery procedure.
Some error messages can be cleared by pressing the Enter button on the
control panel, others by cycling the power to the library. Often the module will
resume normal operation. Other errors are repeated when the operation is
attempted again. Such recurrent errors may require more extensive recovery
procedures, such as replacement of a part.
To aid you in localizing persistent errors, there are Customer Engineer
diagnostics available in the Maintenance Submenu and a user diagnostic
available on the Demo Submenu. The diagnostics are described at the end of
this chapter.
