The Auto DST (
AUTO
) setting will be available only when a city code that supports time calibration
signal reception (page E-15) is selected as the Home City. While Auto DST is selected the DST
setting will be changed automatically in accordance with time calibration signal data.
•
Note that you cannot switch between standard time and daylight saving time (DST) while UTC is
selected as your Home City.
5. After all of the settings are the way you want, press
E
twice to exit the setting screen.
•
Daylight Saving Time is turned on when the
DST
indicator is on the display.
Note
•
After you specify a city code, the watch will use UTC* offsets in the World Time Mode to calculate
the current time for other time zones based on the current time in your Home City.
* Coordinated Universal Time, the world-wide scientifi c standard of timekeeping.
The reference point for UTC is Greenwich, England.
•
Selecting some city codes automatically makes it possible for the watch to receive the time
calibration signal for the corresponding area. See page E-15 for details.

Confi guring Current Time and Date Settings Manually
You can confi gure current time and date settings manually when the watch is unable to receive a time
calibration signal.
Important!
•
Before confi guring current time and date settings, be sure set your Home City (page E-31).
To change the current time and date settings manually
1. In the Timekeeping Mode, hold down
E
for at least two seconds.
SET
and
Hold
will appear on the display fi rst, and then
Hold
will
disappear. Release
E
after
Hold
disappears.

Note
•
While the 12-hour format is selected for timekeeping, a
P
(PM) indicator will appear for times from
noon to 11:59 p.m. No indicator appears for times from midnight to 11:59 a.m. With 24-hour format,
time is displayed from 0:00 to 23:59, without any
P
(PM) indicator.
•
The watch’s built-in full automatic calendar 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 rechargeable battery replaced or after power drops to Level 5 (page E-11).
•
The day of the week changes automatically when the date changes.

Specifying Temperature, Barometric Pressure, and Altitude Display Units
Use the procedure below to specify the temperature, barometric pressure, and altitude display units to be
used in the Barometer/Thermometer Mode and the Altimeter Mode.
Important!
•
When
TYO
(Tokyo) is selected as the Home City, the altitude unit is set
automatically to meters (
m
), the barometric pressure unit to
hectopascals (
hPa
), and the temperature unit to Celsius (
°C
). These
settings cannot be changed.
To specify temperature, barometric pressure, and altitude display
units
1. In the Timekeeping Mode, hold down
E
for at least two seconds.
SET
and
Hold
will appear on the display fi rst, and then
Hold
will
disappear. Release
E
after
Hold
disappears.
2. Press

Using the Altimeter Mode
The watch takes altitude readings and displays results based on air pressure measurements taken by a
built-in pressure sensor. It also saves various types of altitude records and data.
Getting Ready
Before actually taking an altitude reading you need to select an altitude screen format and select an
altitude reading interval.
Selecting the Altitude Screen Format
You can select either of two screen formats for the Altimeter Mode.
Screen 1
Altitude
Tendency Graph
Altitude
Current time
Screen 2
Relative altitude
Altitude
Current time
•
Altitude tendency graph contents are updated each time you take an altitude reading.
•
To take readings of the difference between the altitude at your current location and the altitude at a
reference point, select Screen 2. See “Using an Altitude Differential Value” (page E-42) for more
information.
E-37
To select the altitude screen format
1. Enter the Altimeter Mode (page E-27).
2. Use
E
to toggle the setting between the two screens.
Selecting the Altitude Auto Reading Interval
You can select either of the following two altitude auto reading intervals.
0’05
: Readings at one-second intervals for the fi rst three minutes, and then every fi ve seconds for
approximately the next hour
2’00
: Readings at one-second intervals for the fi rst three minutes, and then every two minutes for
approximately the next 12 hours
Note
•
If you do not perform any button operation while in the Altimeter Mode, the watch will return to the
Timekeeping Mode automatically after 12 hours (altitude auto reading interval:
2’00
) or after one
hour (altitude auto reading interval:
0’05
).
To select the altitude auto reading interval
1. In the Altimeter Mode, hold down
E
for at least two seconds. You can
release
E
after
ALTI
appears.
•
The current altitude reading value will appear at this time.
2. Press
D
to display the current altitude auto reading interval setting.
•
The display will show
0’05
or
2’00
.
3. Press
A
to toggle the altitude auto reading interval setting between
0’05
and
2’00
.
4. Press
E
to exit the setting screen.

Taking Altitude Readings
Use the procedure below to take basic altitude readings.
•
See “Using Reference Altitude Values” (page E-44) for information about how to make altimeter
readings more accurate.
•
See “How does the altimeter work?” (page E-48) for information about how the watch measures altitude.
E-39
To take altitude readings
Enter the Altimeter Mode (page E-27).
•
This will automatically start an altitude reading operation, and the result
will appear on the display as a value in 1-meter (5-foot) units.
•
Readings will continue to be taken about every second for the fi rst
three minutes. For information about the reading interval after that, see
page E-37.
•
You can restart the reading operation from the beginning at any time
by pressing
C
.
Note
•
After you are fi nished, press
D
to return to the Timekeeping Mode and
stop auto altimeter readings.
•
The watch will return to the Timekeeping Mode automatically if you do
not perform any operation (page E-28).
•
The measurement range for altitude is –700 to 10,000 meters (–2,300
to 32,800 feet).
•
The displayed altitude value changes to
- - - -
if an altitude reading
falls outside the measurement range. An altitude value will reappear as
soon as the altitude reading is within the allowable range.
•
Normally, displayed altitude values are based on the watch’s preset
conversion values. You also can specify a reference altitude value, if
you want. See “Using Reference Altitude Values” (page E-44).
•
You can change the unit for displayed altitude values to either meters
(m) or feet (ft). See “To specify temperature, barometric pressure, and
altitude display units” (page E-35).
