other Maintenance Support displays.
The Control software version (VERS) and revision (REV) is displayed as well as the time of the last
failure (TIME OF FAILURE).
Error information is not updated while the display is in view. The HPMM Detail Status display must be
reselected to view changes in the error data.
Notice the reference to access Hard failure codes in the HPM Service manual. Table 58 Communications
