Example: If the time in step 3 is 30 seconds (00:30), when the display changes (to step

4) 00:30 will appear in the time field as the new default time.

You now have two choices:

The time may be changed to another (01:30, for instance) following steps 4 through
6 above (the new time will overwrite the old time automatically).

ii)

The default time of 00:30 may be accepted by pressing the

key after the

speed entry (to accept the speed) and then the

PROG RUN

key to move to the next

step. In this case, by not pressing the

key to accept the previous time (00:30),

the sequence automatically moves to the next

Prog Speed

step.

If the time was changed from 00:30 to 01:30 (and accepted by pressing the

key), this time would become the default time for the next

Prog Speed

step.

c) If a mistake is made in entering speed or time, it may be corrected by pressing the

key twice to move out of the field you are in and back into the field to be changed.

Example: If the speed entered was 25.5, and 25.3 was required, the

key is pressed

twice after 25.5 is entered. This would move the cursor back to the beginning
of the speed field. 25.3 is entered, overwriting the 25.5 entry.

d) The DV-III will accept 0 (zero) as a valid speed, but will not accept 0 as a valid time in

a Prog Speed mode program.
