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 Mainflingen (Germany), Rugby
(England), or Fort Collins (the United States) include 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 signals.
•
The time calibration signals transmitted from Fukushima and Fukuoka/Saga (Japan)
do not include summer time data.
•
The default DST setting is Auto DST (
) whenever you select

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. On the Timekeeping Mode Dual Time screen, make sure the time whose DST
setting you want to change is in the Home Time position on the display.
•
You must make separate DST settings for the Home Time and the Zone 2 Time.
2. Press
A
so the city code is flashing. This is the setting screen.
3. Press
C
and the DST setting screen appears.
4. Use
D
to cycle through the DST settings in the sequence shown below.

Reference
This section contains more detailed and technical information about watch operation.
It also contains important precautions and notes about the various features and
functions of this watch.
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).
MUTE indicator
•
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.
Power Saving Function
When turned on, the Power Saving function enters a
sleep state automatically whenever the watch is left in an
area where it is dark for a certain period. The table below
shows how watch functions are affected by the Power
Saving function.
Power saving indicator
•
Wearing the watch inside the sleeve of clothing can cause it to enter the sleep state.
•
The watch will not enter the sleep state between 6:00 AM and 10:59 PM. If the
watch is already in the sleep state when 6:00 AM arrives, however, it will remain in
the sleep state.

Auto Return Features
•
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 flashing 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 first.
Radio-controlled Atomic Timekeeping Precautions
•
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 reflectivity 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 Receive Mode is the date data
included in the received time calibration signal. When only time data is received,
however, the Receive Mode 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 within ±20 seconds a month at normal temperature.
•
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.
•
You can change the time and city code setting only of the time that is currently in the
Home Time position on the Dual Time screen. You cannot change the settings of
Zone 2 Time position. If you want to change the time or city code setting of the Zone
2 Time, first move it to the Home Time position. After making the changes, you can
move the time back to the Zone 2 Time position.
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 or when battery power drops to
Level 4.
•
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 differential.
•
The UTC differential 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 “Universal Time Coordinated”, which is the
world-wide scientific 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.
12-hour/24-hour Timekeeping Formats
The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is also
applied in all other modes.
•
With the 12-hour format, the PM indicator (
P
) appears on the display for times in the
range of noon to 11:59 p.m. and no indicator appears for times in the range of
midnight to 11:59 a.m.
•
With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without
any indicator.
Illumination
The watch has an EL (electro-luminescent) panel that causes the entire display to
glow for easy reading in the dark. In any mode (except when a setting screen is on the
display), press
B
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.
