Radio-controlled Atomic Timekeeping
This watch receives a time calibration signal and updates its time setting accordingly.
• This watch is designed to pick up the time calibration signals transmitted in Germany
(Mainflingen), England (Anthorn), the United States (Fort Collins), China (Shangqiu),
and Japan (Fukushima, Fukuoka/Saga).
Current Time Setting
This watch adjusts its time setting automatically in accordance with a time calibration
signal. You also can perform a manual procedure to set the time and date, when
necessary.
• The first thing you should do after purchasing this watch is to specify your
Home City (the city where you normally will use the watch). For more
information, see “To specify your Home City” (page E-13).
• 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”
(page E-67) 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.

• As of December 2009, China does not use Daylight Saving Time (DST). If China
does go to the Daylight Saving Time system in the future, some functions of this
watch may no longer operate correctly.
• Using this watch in a country covered by a time calibration that is different from the
countries it supports may result in incorrect time indication due to local application of
summer time, etc.
To specify your Home City
1.In the Timekeeping Mode, hold down A until the city
code starts to flash, which indicates the setting screen.

3. Press A twice to exit the setting screen.
• 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 also can perform manual receive (page
E-27) or you can set the time manually (page E-68).
• 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 page
E-18 and “Transmitters” (page E-88).
• See the maps under “Approximate Reception Ranges” (page E-19) for information
about the reception ranges of the watch.
E-15
• You can disable time signal reception, if you want. See “To turn auto receive on and
off” on page E-29 for more information.
• Under factory default settings, auto receive is turned off for all of the following city
codes: MOW (Moscow), HNL (Honolulu), and ANC (Anchorage). For details about
turning on auto receive for these city codes, see “To turn auto receive on and off” on
page E-29.
Time Calibration Signal Reception
There are two different methods you can use to receive the time calibration signal:
auto receive and manual receive.
• Auto Receive
With auto receive, the watch receives the time calibration signal automatically up to
6 times a day (5 times a day for the Chinese calibration signal). When any auto
receive is successful, the remaining auto receive operations are not performed. For
more information, see “About Auto Receive” (page E-22).
• Manual Receive
Manual receive lets you start a time calibration receive operation with the press of a
button. For more information, see “To perform manual receive” (page E-27).

Important!
• When getting ready to receive the time calibration signal, position the watch as
shown in the nearby illustration, with its 12 o’clock side pointing towards a window.
This watch is designed to receive a time calibration signal late at night. Because of
this, you should place the watch near a window as shown in the illustration when you
take it off at night. Make sure there are no metal objects nearby.

• Signal reception normally is better at night than during the day.
• Time calibration signal reception takes from two to seven minutes, but in some
cases it can take as long as 14 minutes. Take care that you do not perform any
button operations or move the watch during this time.

• The time calibration signal the watch will attempt to pick up depends on its current
Home City code setting as shown below.

* The areas covered by the HNL, ANC, and MOW city codes are quite far from the
time calibration signal transmitters, and so certain conditions may cause problems
with signal reception.
• Calibration signal reception is disabled while a countdown timer operation is in
progress.
