Auto Summer Time (DST) Switching
The time calibration signal transmitted from Mainflingen, Germany includes both
standard time and summer time (Daylight Saving Time) data. When auto summer time
(DST) switching is turned on, the watch switches between standard time and summer
time (DST) automatically in accordance with the calibration signal.
• Daylight Saving Time (DST) advances the time setting by one hour from Standard
Time. Remember that not all countries or even local areas use Daylight Saving Time.
• When using the watch within the reception range of the Mainflingen transmitter, and
BER, PAR, LON, or ATH is selected as the Home City code, select AUTO DST to
turn on the auto summer time setting.
• The default auto summer time setting is AUTO DST whenever you select BER, PAR,
LON or ATH as your Home City code.
• If you experience problems receiving the time calibration signal in your area, it is
probably best to turn off auto time switching.
To select the auto summer time setting
1. In the Timekeeping Mode, press B. This causes the current auto receive on/off
setting (the receive indicator) to flash, which indicates the setting screen.
2. Press C twice until the summer time (DST) setting screen appears.
3. Use D to cycle through the summer time settings in the sequence shown below.
4. When the setting you want is selected, press B to exit the setting screen.

the watch.
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 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 you have the watch's 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.

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.
