During startup and also during normal monitor operations, diagnostic
programs running in the background environment provide a constant
monitoring of critical hardware components and software functions.
In the event a critical component or software function is determined by the
software to be malfunctioning or there is no response to a requested task,
the diagnostics may force a full or partial main processor reset. Such events
can be identified by either a temporary loss of display or by a highly audible
watchdog alert tone. Monitor resets are typically recorded in the diagnostic
error log, which can be retrieved for interpretation and diagnosis by factory
trained experts.
Should a monitor exhibit symptoms of a reset, compare contents of the
diagnostic error log with the list of Error Messages and Diagnostic Codes
in Appendix C, for possible remedial action. Otherwise, record the
information on a copy of the
Chapter, and forward it along with the diagnostic error log to your respective
TSS center.
