The display will show the parameters that were last entered for this program.
If any of the parameters are changed, the ENTER button must be pressed for
the new value to be stored. If ENTER is not pressed within 10 seconds after
the last parameter adjustment, the value will return to the previously stored
value. The flashing parameter name shows the parameter that will be
changed. Pressing ENTER only will advance to the next parameter.
After the AUTO RUN cycle is started, segments with a value greater than the
segment running may have their parameters changed. Only the selected
program may be modified. To modify a different program, the system must
be stopped and the desired program selected.
Starting the Freeze Dry Cycle
After the desired cycles have been programmed, push the MODE button to
