Bright light
Solar cell
Keep the watch exposed to bright light
The electricity generated by the solar cell of the watch is
stored by a built-in battery . Lea ving or using the watch
where it is not exposed to light causes the battery to run
down. Make sure the watch is exposed to light as much as
possible.
• When you are not wearing the watch on y our wrist,
position the face so it is pointed at a source of bright
light.
• Y ou should try to keep the watch outside of y our sleeve
as much as possible . Even if the f ace of the watch is
block ed only partially from light, charging will be reduced
significantly .
• The watch contin ues to operate, ev en when it is not exposed to light. Leaving the
watch in the dark can cause the battery to run down, which will cause some watch
functions to be disabled. If the batter y goes dead, you will hav e to re-configure watch
settings after recharging. T o ensure normal watch operation, be sure to keep it
exposed to light as m uch as possible.

Radio-controlled Atomic Timekeeping
This watch receives a time calibration signal and updates its time setting accordingly .
• Supported time calibration signals: Germany (Mainflingen), England (Anthorn),
United States (F or t Collins), Japan (Fukushima or Fukuoka/Saga).
• See the information under “Signal Reception T roubleshooting” if you e xperience
problems with time calibr ation signal reception.

signal. Y ou also can perf or m a manual procedure to set the time and date, when

• The first thing y ou should do after purchasing this watch is to specify y our
Home City , which is the city where y ou will normally use the watch. For more
information, see “T o specify your Home City”.
• When using the watch outside the areas cov ered by the time calibration signal
transmitters, y ou will hav e to adjust the current time setting manually as required.
See “Timek eeping” f or more information about manual time settings.
• The U.S . time calibration signal can be pick ed up by the watch while in North
America. The term “Nor th America” in this manual ref ers to the area that consists of
Canada, the continental United States, and Me xico .

• Even if the time calibr ation signal is received correctly , there are some times when
the analog hands may not indicate the correct time . If this happens, use the
procedures under “Adjusting the Home P ositions” to check the home positions of the
hands, and make adjustments as required.
• Y ou can also change the Home City setting b y sw apping the current Home City and
the currently selected World Time City . For details , see “Swapping y our Home City
and World Time City”.
Daylight Saving Time (DST)
Daylight Sa ving Time (summer time) adv ances the time setting by one hour from
Standard Time . Remember that not all countries or ev en local areas use Da ylight
Saving Time.
The time calibration signals transmitted from Mainflingen (Germany), Anthorn
(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 betw een Standard
Time and DST (summer time) automatically in accordance with the signals.
• Though the time calibration signal transmitted by the Fukushima and Fukuoka/Saga,
Japan transmitters include summer time data, summer time currently is not
implemented in Japan (as of 2007).
• The default DST setting is A uto DST (AUTO /AT ) whenev er you select LON , PA R ,
AT H , ANC, LAX , DEN , CHI , NYC , or TY O as your Home City code.
• If you e xperience problems receiving the time calibration signal in y our area, it
probably is best to s witch between Standard Time and Daylight Sa ving Time (summer
time) manually . For more inf ormation, see “T o set the time and date man ually”.
