Using Summer Time
Summer time, or Daylight Saving Time (DST) as it is called in some countries, calls for
setting clocks ahead one hour from standard time during the summer season.
Note that the start and end of summer time, and whether summer time is used at all
depends on each country and geographic area.
• ON
Turns on summer time and advances standard time by one hour.
• OFF
Turns off summer time and returns to standard time.
To turn on summer time (DST) for a World Time city
�������������
1. In the World Time Mode, use D (eastward) and B
(westward) to scroll through the city codes until the one
whose summer time (DST) setting you want to change
is displayed.
2. Hold down A to toggle the displayed city’s summer
time setting on ( DST displayed, time advanced by one
hour) or off ( DST not displayed, standard time).
• If the currently selected city is also your Home City, the
summer time (DST) setting you select here also will be
applied in the Timekeeping Mode.
Illumination
This watch has 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.
Illumination Precautions
• The electro-luminescent panel that provides illumination loses power after very long
use.
• Illumination 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.
• Illumination turns off automatically whenever an alarm sounds.
• Frequent use of illumination runs down the battery.
Troubleshooting
The watch does not count my steps.
• The watch maintains a step count only while a stopwatch elapsed time operation is
in progress. Steps are not counted while the stopwatch is stopped (display showing
all zeros or a timing paused).
