F) POWER DOWN:

When the OptiMix is powered down the last used SAVED program will
be recalled when the unit is turned on. If a modified program is being
used it should be SAVED before the OptiMix is turned off. Failure to
SAVE a program will result in the program being deleted on power
down.

G) DISPLAY SCREEN MESSAGES:

mixing cycle will stop as shown in (Figure 3G-1).
Mix Aborted
Appears if any key is pressed while the machine is running and then
the mixing cycle will stop as shown in (Figure 3G-2).
Invalid Setting
Appears if the entered values for time or speed, or the format, are

displayed if an attempt is made to change a setting on a hard coded
program location 10-thru 40 as shown in (Figure 3G-3).
Sensor Error
Appears when there is a loss of speed sensor signal as shown in
