Timekeeping
• The day of the week is automatically displayed in accordance with the date
(year, month, and day) settings.
• The year can be set in the range of 2000 to 2039.
• The watchís 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 you have the watchís battery
replaced.
• The current time for all city codes in the Timekeeping Mode is calculated in
accordance with the Greenwich Mean Time (GMT) differential for each city,
based on the your Home City time setting.
• GMT differential is calculated by this watch based on Universal Time
Coordinated (UTC
*
) data.
*
The letters “UTC” stands for “Universal Time Coordinated,” which is the
world-wide scientific standard of timekeeping. It is based upon carefully
maintained atomic (cesium) clocks that keep accurate to within
microseconds. Leap seconds are added or subtracted as necessary to keep
UTC in sync with the Earth’s rotation. The reference point for UTC is
Greenwich, England.
12-hour/24-hour Timekeeping Formats
The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode
is also applied in all other modes.
• With the 12-hour format, the P (PM) indicator appears on the display for
times in the range of noon to 11:59 p.m. and the no indicator appears for
times in the range of midnight to 11:59 a.m.
• With the 24-hour format, times are displayed in the range of 0:00 to 23:59,
with 24 indicator.

Data Memory Management
Data memory can hold up to 315 characters total, while each record can
contain up to 63 characters. This means that 40 records can be stored in data
memory when each record contains seven characters of text or less.
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 L to illuminate the display for about one second.
• 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.
