Radio Controlled Atomic Timekeeping
This watch receives a time calibration signal and updates its time setting accordingly.
However, when using the watch outside of areas covered by time calibration signals,
you will have to adjust the settings manually as required. See “Configuring Current
Time and Date Settings Manually” (page E-45) for more information.
This section explains how the watch updates its time settings when the city name
selected as the Home City is in Japan, North America, Europe, or China, and is one
that supports time calibration signal reception.
If your Home City Name setting is this:
The watch can receive the signal from the
transmitter located here:
LISBON, LONDON, MADRID, PARIS, ROME,
BERLIN, STOCKHOLM, ATHENS, MOSCOW
Anthorn (England), Mainflingen (Germany)
HONG KONG, BEIJING Shangqiu City (China)
TAIPEI, SEOUL, TOKYO Fukushima (Japan), Fukuoka/Saga (Japan)
E-22
If your Home City Name setting is this:
The watch can receive the signal from the
transmitter located here:
HONOLULU, ANCHORAGE, VANCOUVER,
LOS ANGELES, EDMONTON, DENVER,
MEXICO CITY, CHICAGO, NEW YORK,
HALIFAX, ST. JOHN’S
Fort Collins, Colorado (United States)
Important!
• The areas covered by
MOSCOW
,
HONOLULU
and
ANCHORAGE
are quite far
from the calibration signal transmitters, so certain conditions may cause reception
problems.
• When
HONG KONG
or
BEIJING
is selected as the Home City, only the time and
date are adjusted according to the time calibration signal. You need to switch
manually between standard time and daylight saving time (DST) if required. See “To
configure Home City settings” (page E-40) for information about how to do this.

• Even when the watch is within range of a transmitter, signal reception may be
impossible due to the effects of geographic contours, structures, weather, the time
of year, the time of day, radio interference, etc. The signal becomes weaker at
distances of approximately 500 kilometers, which means that the influence of the
conditions listed above becomes even greater.
• Signal reception may not be possible at the distances noted below during certain
times of the year or day. Radio interference may also cause problems with
reception.
Mainflingen (Germany) or Anthorn (England) transmitters: 500 kilometers (310
miles)
Fort Collins (United States) transmitter: 600 miles (1,000 kilometers)
Fukushima or Fukuoka/Saga (Japan) transmitters: 500 kilometers (310 miles)
Shangqiu (China) transmitter: 500 kilometers (310 miles)
• As of January 2011, 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.
E-25
• When your Home City is
TOKYO
(which can receive both 40 kHz and 60 kHz
signals), the watch first tries to pick up the signal it last successfully received. If that
fails, it tries the other signal.
• 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.
E-26
To get ready for a receive operation
1. Confirm that the watch is in the Timekeeping Mode. If it isn’t, use
D
to enter the
Timekeeping Mode (page E-36).
2. The antenna of this watch is located on its 12 o’clock side. Position the watch with
12 o’clock facing towards a window as shown in the nearby illustration. Make sure
there are no metal objects nearby.
• Signal reception normally is better at
night.
• The receive operation takes from three
to eight minutes, but in some cases
it can take as long as 16 minutes.
Take care that you do not perform any
button operation or move the watch
during this time.

3. What you should do next depends on whether you are using Auto Receive or
Manual Receive.
• Auto Receive: Leave the watch over night in the location you selected in step 2.
See “Auto Receive” below for details.
• Manual Receive: Perform the operation under “To perform manual receive” on
page E-29.
Auto Receive
• With Auto Receive, the watch performs the receive operation each day
automatically up to six times (up to five times for the Chinese calibration signal)
between the hours of midnight and 5 a.m. (according to the Timekeeping Mode
time). When any receive operation is successful, none of the other receive
operations for that day are performed.
• When a calibration time is reached, the watch will perform the receive operation
only if it is in the Timekeeping Mode or World Time Mode. The receive operation is
not performed if a calibration time is reached while you are configuring settings.
• You can use the procedure under “To turn auto receive on and off” (page E-33) to
enable or disable auto receive.
E-29
To perform manual receive
1. Enter the Timekeeping Mode (page E-36).
2. Hold down
E
.
• Keep
E
depressed until the receiving indicator
starts to flash on the display.
• A signal level indicator (L1, L2, or L3; see page
E-31) appears on the display after reception starts.
Do not move the watch or perform any button
operation until GET or ERR appears.
• If the receive operation is successful, the reception
date and time will appear on the display, along
with the GET indicator. The watch will return to the
Timekeeping Mode if you press
E
or if you do not
perform any button operation for about one or two
minutes.
