There are six push-buttons on the control panel, and these are used to ad-

The keys have been assigned the following functions:
Control Panel Functions (continued)
The operating parameters can be displayed and checked with the MENU
key.
Each time the MENU key is pressed, another one of the six operational
parameters will be displayed.
Whenever a new setting is made, it will take effect immediately. Further-
more, since all settings are saved in memory, it will automatically be used
the next time the system is powered up.
The operating parameter that is currently being displayed can be raised or
lowered by pressing the PLUS ("+", increases the displayed value) and
MINUS ("-", reduces the displayed value) keys respectively.
Pressing the PAUSE/STOP key allows the operator to exit the setup menu
without changing the parameter currently being displayed.
While running:
Pressing PAUSE/STOP once interrupts the current staining operation so
that another slide carrier can be placed in the lift bar.
Pressing PAUSE/STOP twice (in quick succession) terminates the current
program, and the system returns to idle mode.
If the ENTER key is pressed, the selected parameter is stored in the
system.
The system returns to its idle mode whenever a new setting is entered, or
whenever the user exits the setup menu by pressing the PAUSE/STOP
key,
Pressing the RUN key starts a staining operation on the basis of the values
shown in the display. At the same time, the flushing valve is activated, the
display changes, and the timer appears, counting down to show the re-
maining processing time.
