Precautions Concerning Simultaneous Measurement of
Altitude and Temperature
Though you can perform altitude and temperature measurements at the same time,
you should remember that each of these measurements requires different conditions
for best results. With temperature measurement, it is best to remove the watch from
your wrist in order to eliminate the effects of body heat. In the case of altitude
measurement, on the other hand, it is better to leave the watch on your wrist, because
doing so keeps the watch at a constant temperature, which contributes to more
accurate altitude measurements.
•
To give altitude measurement priority, leave the watch on your wrist or in any other
location where the temperature of the watch is kept constant.
•
To give temperature measurement priority, remove the watch from your wrist and
allow it to hang freely from your bag or in another location where it is not exposed
to direct sunlight. Note that removing the watch from your wrist can affect pressure
sensor readings momentarily.
To specify standard time or daylight saving time (DST) for a city
1. In the World Time Mode, use D (East) to display the
city code (time zone) whose Standard Time/Daylight
Saving Time setting you want to change.
2. Hold down A until DST Hold appears on the display
and then disappears. Release A after DST Hold
disappears.
•
This toggles the city code you selected in step 1
DST indicator

between Daylight Saving Time (DST indicator
displayed) and standard time (DST indicator not
displayed).
•
You cannot use the World Time Mode to change the current standard time/
daylight saving time (DST) setting of the Home City.
•
Note that you cannot switch between standard time/daylight saving time (DST)
while UTC is selected as the World Time City.
•
Note that the standard time/daylight saving time (DST) setting affects only the
currently selected time zone. Other time zones are not affected.

Note
•
The Stopwatch Mode can indicate elapsed time up to 23 hours, 59 minutes, 59.99
seconds.
Once started, stopwatch timing continues until you press A to stop it, even if you
•
exit the Stopwatch Mode to another mode and even if timing reaches the stopwatch
limit defi ned above.
•
Exiting the Stopwatch Mode while a split time is frozen on the display clears the
split time and returns to elapsed time measurement.
2. Hold down A until the hour setting of the current countdown start time starts to
fl ash. This is the setting screen.
•
Before the hour setting starts to fl ash, the message SET Hold will appear on the
display. Keep A depressed until SET Hold disappears and the hour setting
starts to fl ash.
3. Press C to move the fl ashing between the hour and minute settings.
4. Use D (+) and B (–) to change the fl ashing item.
•
To set the starting value of the countdown time to 24 hours, set 0H 00'00.
5. Press A to exit the setting screen.
