minute column shows 59 minutes, a one is added to the number in the
hour column.The day, month, and year columns are similarly increment-
ed. For example, if the seconds column is reset on December 31, 2003, at
23 hours, 59 minutes, and 45 seconds, the time will change to January 1,
2004, 0 hours, 0, minutes, 0 seconds.
b) Adjusting the day display
Months that have 31 days can be set to any day up to 31.
Months that have 30 days can be set to any day up to 30.
February can be set to any day up to 28, except in a leap year, when it
can be set up to the 29th.
(Days that do not exist, such as June 31, November 31, and so forth, are
not displayed.)
When the day is being adjusted, the month column does not change even
after the last day in the month is passed. (The day loops, without affect-
ing the month.)
c) Adjusting the month display
The end of the month is controlled during adjustment of the month col-
umn, and days that do not exist are handled as follows. If the dive com-
puter indicates the 31st day of a month when the display is reset to a
month with 30 days, the day column will indicate the first day of that
month, since the 31st day does not exist.
Examples:
If the D key is pressed once when the dive computer indicates May 31,
the date will change to June 1 (because there are not 31 days in June).
If the D key is pressed once when the dive computer indicates January
30, the date will change to February 1 (because February 30 does not
exist).
Note: In the case of a leap year, if the D key is pressed once when the
dive computer indicates January 29, the dive computer will indicate
February 29. The year column does not change when the month column
changes from December to January. (The month loops, without affecting
the year column.)
