ERRONEOUS FAILURE DISPLAYS

Erroneous Warning, Caution or Advisory Alerts, Red X's, or
Erroneous Exceedence displays.
There is a remote chance that an alert, red X or red
exceedence display may be erroneously displayed.
If it is suspected that an erroneous failure display has
occurred:
1. Use other system information to determine if the failure
display is valid.
If the validity of the failure display cannot be confirmed:
2. Assume the failure display is valid and follow the appro-
priate Emergency or Abnormal procedures.
