up tests and is fully functional. The machine will proceed to the
MACHINE MONITOR screen after a short delay.

FUNCTIONAL: detected. The NARKOMED 2C will retain this display until the trigger
is pressed, then the MACHINE MONITOR screen will be displayed.

the display panel. The following paragraphs provide a description of each service screen that
can be accessed at the display. If no display is present upon system power-up, refer to Section
