• When using the watch outside the areas covered by the time signal transmitters, you
will have to adjust the current time setting manually as required. See “Timekeeping”
for more information about manual time settings.
• The U.S. time calibration signal can be picked up by the watch while in North
America. The term “North America” in this manual refers to the area that consists of
Canada, the continental United States, and Mexico.
• Make sure the watch is facing the right way.

• Normally, your watch should show the correct time as soon as you select your Home
City code. If it does not, it should adjust automatically after the next auto receive
operation (in the middle of the night).You can also perform manual receive or you
can set the time manually.
• The watch will receive the time calibration signal automatically from the applicable
transmitter (in the middle of the night) and update its settings accordingly. For
information about the relationship between city codes and transmitters, see “Home
City Codes and Transmitters”.
• Under factory default settings, auto receive is turned off for all of the following city
codes: HNL (Honolulu), ANC (Anchorage), ATH (Athens), and MOW (Moscow). For
details about turning on auto receive for these city codes, see “To turn auto receive
on and off”.
• The time calibration signal the watch will attempt to pick up depends on its current
Home City code setting as shown below.

Operation Guide 3054
• If you are in an area where proper time calibration signal reception is impossible, the
Daylight Saving Time (DST)
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.
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 Rugby
(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 (
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.
The following are the initial factory defaults for these settings.

• 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.
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.
• 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.

of the watch’s buttons.You can turn the button operation
tone on or off as desired.
• Illumination may be hard to see when viewed under direct sunlight.

Hourly Time Signal, and Countdown Timer Mode alarm
all operate normally.
• Illumination automatically turns off whenever an alarm sounds.
• Frequent use of illumination runs down the battery.

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 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.

• 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.
