Epson 10020 - Manual (Page 139)

If you enter an invalid time-for example, a number
greater than 23 for the hours or greater than 59 for the
minutes or seconds-the computer keeps and ignores your
entry. Try again. You can use the backspace key, if
necessary, to correct mistakes.
When the time is correct, press Enter.
4. To set the date, highlight Date and press Enter. You see
this box:
m m - d d - y y
—
S. Enter the date in the exact format shown in the box, using
two digits for the month and day and four digits for the
year; the program automatically inserts the dashes. For
example, to set the date for August 30, 1989, you would
type the following:
08301989
If you enter an invalid date-for example, a number greater
than 12 for the month or greater than the number of days
in that month-the computer keeps and ignores your entry.
Try again.
When the date is correct, press Enter.
6. When both the time and
date
are correct, press once or
twice to return to the main Setup menu.
The time and date are set automatically as soon as you press
Enter after typing the time and date; you do not need to save
these settings. Therefore, if you change either setting in the
Setup program and then exit the program without saving your
changes, the new time or date still takes effect.
