Setting the Time and Date
Make sure you select your Home City code before you change the current time
and date settings. World Time Mode times are all displayed in accordance with the
Timekeeping Mode settings. Because of this, World Time Mode times will not be
correct if you do not select the proper Home City code before setting the time and
date in the Timekeeping Mode.

1. In the Timekeeping Mode, hold down
A
until the city
code starts to fl ash, which indicates the setting screen.
2. Press
C
to change the fl ashing contents in the
sequence shown below to select other settings.

Auto Display cannot be performed while a setting screen is on the display.
Button Operation Tone
The button operation tone sounds any time you press one
of the watch’s buttons. You can turn the button operation
tone on or off as desired.
•
Even if you turn off the button operation tone, the alarm,
Hourly Time Signal, and Countdown Timer Mode alarm
all operate normally.
To turn the button operation tone on and off
In any mode (except when a setting screen is on the
display), hold down
C
to toggle the button operation tone
on ( MUTE not displayed) and off ( MUTE displayed).
•
Since the
C
button is also the mode change button, holding it down to turn the
button operation tone on or off also causes the watch’s current mode to change.
•
The MUTE indicator is displayed in all modes when the button operation tone is
turned off.
Auto Return Features
•
If you leave the watch with the Last Signal screen in the Timekeeping Mode for one
or two minutes without performing any operation, it returns to the Current Time and
Date screen in the Timekeeping Mode automatically.
•
If you leave the watch in the Alarm Mode for two or three minutes without performing
any operation, it returns to the Timekeeping Mode automatically.
•
If you leave the watch with a fl ashing setting on the display for two or three minutes
without performing any operation, the watch exits the setting screen automatically.
Scrolling
The
B
and
D
buttons are used in various modes and setting screens to scroll
through data. In most cases, holding down these buttons during a scroll operation
scrolls through the data at high speed.
Initial Screens
•
When you enter the World Time or Alarm Mode, the data you were viewing when
you last exited the mode appears fi rst.
Radio-controlled Atomic Timekeeping Precautions
•
The display of the watch is blank while an auto receive operation is in progress.
•
Strong electrostatic charge can result in the wrong time being set.
•
The time calibration signal is bounced off the ionosphere. Because of this, such
factors as changes in the refl ectivity of the ionosphere, as well as movement of the
ionosphere to higher altitudes due to seasonal atmospheric changes or the time of
day may change the reception range of the signal and make reception temporarily
impossible.
•
Even if the time calibration signal is received properly, certain conditions can cause
the time setting to be off by up to one second.
•
The current time setting in accordance with the time calibration signal takes priority
over any time settings you make.
•
The watch is designed to update the date and day of the week automatically for
the period January 1, 2000 to December 31, 2099. Setting of the date by a time
calibration signal cannot be performed starting from January 1, 2100.
•
This watch can receive signals that differentiate between leap years and non-leap
years.
•
Though this watch is designed to receive both time data (hour, minutes, seconds)
and date data (year, month, day), certain signal conditions can limit reception to time
data only.
•
Normally, the signal reception date shown by the Last Signal screen is the date data
included in the received time calibration signal. When only time data is received,
however, the Last Signal screen shows the date as kept in the Timekeeping Mode at
the time of signal reception.
•
If you are in an area where proper time calibration signal reception is impossible, the
watch keeps time with the precision noted in “Specifi cations”.
•
If you have problems with proper time calibration signal reception or if the time
setting is wrong after signal reception, check your current city code, DST (summer
time), and auto receive settings. The following are the initial factory defaults for
these settings.

Timekeeping
•
Resetting the seconds to 00 while the current count is in the range of 30 to 59
causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are
reset to 00 without changing the minutes.
•
The day of the week is displayed automatically in accordance with the date (year,
month, and day) settings.
•
The year can be set in the range of 2000 to 2099.
•
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 battery replaced.
•
The times for the Timekeeping Mode and all the city codes of the World Time Mode
are calculated in accordance with each city’s UTC offset.
•
The UTC offset is a value that indicates the time difference between a reference
point in Greenwich, England and the time zone where a city is located.
•
The letters “UTC” is the abbreviation for “Coordinated Universal Time”, which is the
world-wide scientifi c standard of timekeeping. It is based upon carefully maintained
atomic (cesium) clocks that keep time accurately to within microseconds. Leap
seconds are added or subtracted as necessary to keep UTC in sync with the Earth’s
rotation.

Auto DST (

DEN , MEX , YWG , CHI , MIA , YTO , NYC , YHZ , YYT , LIS , LON , MAD , PAR ,
ROM , BER , STO , ATH , or MOW is selected as the Home City code. For more
information, see “Daylight Saving Time (DST)” below.
4. Press

to exit the setting screen.
Daylight Saving Time (DST)
Daylight Saving Time (summer time) advances the time setting by one hour from
Standard Time. Remember that not all countries or even local areas use Daylight
Saving Time.
The time calibration signals transmitted from Fort Collins (the United States) or
Anthorn (England) includes both Standard Time and DST data. When the Auto DST
setting is turned on, the watch switches between Standard Time and DST (summer
time) automatically in accordance with the received time signal.
•
The default DST setting is Auto DST (
) whenever you select ANC , YVR ,
LAX , YEA , DEN , MEX , YWG , CHI , MIA , YTO , NYC , YHZ , YYT , LIS , LON , MAD ,
PAR , ROM , BER , STO , ATH , or MOW as your Home City code.
•
If you experience problems receiving the time calibration signal in your area, it
probably is best to switch between Standard Time and Daylight Saving Time (summer
time) manually.
To change the Daylight Saving Time (summer time) setting
1. In the Timekeeping Mode, hold down
A
until the city code starts to fl ash, which
indicates the setting screen.
2. Press
C
and the DST setting screen appears.
3. Use
