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 Mainfl ingen (Germany), Anthorn
(England), and 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 (Daylight Saving Time) automatically in accordance with the signals.
•
Though the time calibration signals transmitted by the Fukushima and Fukuoka/
Saga, Japan transmitters include summer time data, summer time currently is not
implemented in Japan (as of 2013).
•
The default DST setting is Auto DST (AUTO) whenever you select LIS, LON, MAD,
PAR, ROM, BER, STO, ATH, MOW, TYO, ANC, YVR, LAX, YEA, DEN, MEX, CHI,
MIA, YTO, NYC, YHZ, or YYT 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.

Hand Home Position Correction
The hands of the watch can be thrown off by exposure to strong magnetism or impact.
If that happens, check if the home positions of the hands are correct and adjust the
home positions as required.
To adjust the home positions

three seconds, until H-SET appears on the upper

Wearing the watch inside the sleeve of clothing can cause it to enter the sleep

•
The watch will not enter the sleep state between 6:00 AM and 9:59 PM. If the watch
is already in the sleep state when 6:00 AM arrives, however, it will remain in the
sleep state.
To recover from the sleep state
Perform any one of the following operations.
•
Move the watch to a well-lit area.
•
Press any button.
•
Angle the watch towards your face for reading (page E-47).
Radio-controlled Atomic Timekeeping Precautions
•
Strong electrostatic charge can cause the time setting to be thrown off.
•
The time calibration signal bounces 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
or

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 manually.
•
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.
1. In the Timekeeping Mode, hold down A for about fi ve
seconds, until the watch beeps twice and the city code
fl ashes on the upper display. This is the setting mode.
