About the memory data display
Data stored in memory appears in one of the formats shown below, depending
on the measurement method (auto or manual), or whether it is the maximum
or minimum reading.
• Auto Memory Data
*
An altitude graph appears in place of the date for the display of data
between the start and end data. The altitude graph divides by 8 the
difference between the maximum and minimum altitudes achieved during
the auto memory measurement, and shows relative changes.

WORLD TIME FUNCTIONS
The World Time Mode shows the current
time in 27 cities (29 time zones) around the
world.
• For full information on city codes, see the
“CITY CODE TABLE”.
• The Home Time differential shows the
difference between the time in the
currently displayed city and the city that
is selected in the Timekeeping Mode.
• The time zone that is displayed when you
leave the World Time Mode will still be
displayed when you enter the World
Time Mode again.
Timekeeping in the World Time Mode
The current time in all the World Time zones is calculated in accordance with
the Greenwich Mean Time (GMT) differential for each zone, based on the
current home time setting in the Timekeeping Mode.
You can also turn Daylight Saving Time (DST) on or off separately for each
time zone. Turning on daylight saving time automatically advances the
corresponding time setting by one hour.
• The seconds count of the World Time is synchronized with the seconds
count in the Timekeeping Mode.
• The 12-hour/24-hour format of the World Time matches the format you
select in the Timekeeping Mode.
• With daylight saving time, clocks are set one hour later in order to better
take advantage of daylight hours during the summer, when days are longer.
Whether or not daylight saving time is used depends on the country you are
in.
Viewing the Time in Another Zone
1. Use C to enter the World Time Mode.
2. Press D to scroll forward through the city codes (time zones) and B to
scroll back.
• Holding down either button scrolls through the city codes at high speed.
Switching a Zone between Standard Time and
Daylight Saving Time
1. In the World Time Mode, display the time
zone (city code) whose standard time/
daylight saving time setting you want to
change.
• You can make separate settings for each
zone (city).
2. Hold down A for about one second to
toggle daylight saving time on (DST
displayed) and off (DST not displayed).
• The DST indicator appears whenever daylight saving time is turned on for
the zone (city) whose time is currently on the display.
