2039.
The watch's built-in full automatic calendar automatically makes allowances
•
for different month lengths and leap years. Once you set the date, there
should be no reason to change it except after the replacement of the watch's
battery.
Daylight Saving Time (DST), which is also sometimes called "summer time"
advances the time for one hour, as is the custom in some areas during the
summer. Remember that not all countries or even local areas use Daylight
Saving Time.
Backlight Precautions
The backlight uses an EL (electro-luminescent) panel that causes the entire
display to glow for easy reading in the dark.
In any mode, press to illuminate the display for about three seconds.
L
• The electro-luminescent panel that provides illumination loses power after
very long use.
The illumination provided by the backlight may be hard to see when viewed
•
under direct sunlight.
The watch may emit an audible sound whenever the display is illuminated.
•
This is due to vibration of the EL panel used for illumination, and does not
indicate malfunction.
The backlight automatically turns off whenever an alarm sounds.
•
Frequent use of the backlight shortens the battery life.

Day Counter Mode
The Day Counter Mode lets you count the number of days from the
Timekeeping Mode's current date to a specific target date.
This watch has five day counters. You can assign text titles up to eight
characters long to each of the five Day Counters. Whenever the date specified
by any one of the day counters matches the date of the Timekeeping Mode
(regardless of the day counter' s year setting), the DAYS indicator flashes on
the Timekeeping Mode. In the Day Counter Mode, the DAYS indicator flashes
on the screen of the particular day counter whose date matches the date of the
Timekeeping Mode.
The initial default date for all Day Counters is January 1, 2001.
