This is the default menu, that menu which appears
upon power up of the Analyzer each time. This menu
displays the current Help (fault) message. This
message is intended to quickly guide a user in the
event of a fault in the control system. This menu is
also intended to display functional interlocks.
Pressing ENTER views Logged Help records of the
last 25 Help (fault) messages. This menu can be
viewed at access Levels 2 and 3.
Note: The Help Messages are prioritized according to
DTC/Service Code (9-9 is highest, No Flash Code is
