During the PRECOOL stage the TIME REMAINING line counts down the time for that stage in
1-second increments.
After the PRECOOL stage comes the first GRINDING stage, and the screen displays STATUS:
GRINDING. The TIME REMAINING line will display the time left in that grinding stage. If there
are 3 grinding periods, during the first one the CYCLES REMAINING line will display 3 OF 3,
during the second the CYCLES REMAINING line will display 2 of 3, etc. In every stage the TIME
REMAINING line will count down the time left in that stage in 1-second increments.
If the program on the CURRENT SETTINGS screen shown in Figure 5 were being run and 15
seconds of the second grinding period had elapsed, the STATUS screen would appear as in
Figure 6.

and (in the case of the program displayed in Figure 4) CYCLES REMAINING will display 0 of 3.
