• See “City Code Table” for a complete list of available city codes.
• Auto DST (A) can be selected only while HNL , ANC , LAX , DEN , CHI , NYC ,
HKG , SEL , or TYO is selected as the Home City code. For more information,
see “Daylight Saving Time (DST)” below.
• For information about setting other than the time and date, see the following.

4. Press A 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 signal transmitted from Fort Collins 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 time calibration signals transmitted from Fukushima and Fukuoka/Saga do not
include summer time data.
• The default DST setting is Auto DST (A) whenever you select LAX , DEN , CHI ,
NYC , or TYO as your Home City code.
• If you experience problems receiving the time calibration signal in your area, it is
probably 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 flash, which
indicates the setting screen.
2. Press C and the DST setting screen appears.
3. Use D to cycle through the DST settings in the sequence shown below.
Auto DST ( A ) DST off ( OF ) DST on ( ON )
4. When the setting you want is selected, press A to exit the setting screen.
• The DST indicator appears to indicate that Daylight Saving Time is turned on.

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.
• 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 the 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 within ±15 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. The following are the initial factory defaults for these
settings.

Note
• The following procedure applies when you have TYO (Tokyo) or SEL (Seoul)
selected as your Home City. If you are using the watch in the U.S., see “To configure
the auto receive setting for the U.S.”.
1. In the Timekeeping Mode, press D to display the last
signal screen.
• The watch will automatically return to the
Timekeeping Mode if you do not perform any button
operation for two or three minutes after displaying the
last signal screen.
2. Hold down A until the Japan auto receive indicator and
the receiving indicator flash on the display. This is the
setting screen.
• Note that the setting screen will not appear if the
currently selected Home City is one that does not
support time calibration reception.

3. Use D or B to specify the transmitter selection mode you want to use.
• Each press of D or B cycles through the available auto receive settings
described below.
: Auto receive on. The watch automatically selects the transmitter whose
signal is strongest. Signal reception can take up to 12 minutes when this
option is selected.
: Auto receive on for reception of the Fukushima signal (40kHz).
: Auto receive on for reception of the Fukuoka/Saga signal (60kHz).
: Auto receive off.
4. Press A to exit the setting screen.
• To return to the Timekeeping Mode from the last signal screen, press D.
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 current time for all city codes in the Timekeeping Mode and World Time Mode is
calculated in accordance with the Greenwich Mean Time (GMT) differential for each
city, based on your Home City time setting.
• GMT differential is calculated by this watch based on Universal Time Coordinated
(UTC*) data.
* UTC 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.
The reference point for UTC is Greenwich, England.
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 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.
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.
