Radio-controlledTimekeeping
This watch is designed to pick up a time calibration signal
transmitted from Mainflingen, Germany (located 25
kilometers southeast of Frankfurt), and update its time
setting accordingly. The time calibration signal includes
both Standard Time and Daylight Saving Time (summer
time) data.
CurrentTime Setting
This watch automatically adjusts its time setting in
accordance with a time calibration signal.You can also
perform a manual procedure to set the time and date,
when necessary.
• The first thing you should do after purchasing this watch
is to set your Home City, which is the city where you will
normally use the watch. For more information, see “To
set your Home City” below.
• See “Setting the Digital Time and Date Manually” for
information about manual settings.

Frankfurt, Vienna
LON: London
3. Press Atwice to exit the setting screen.
City code
• 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.
• If you are in an area that does not use Daylight Saving
Time (summer time), turn off the DST setting.
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 automatically picks up the time calibration signal four
times a day at 2:00 AM, 3:00 AM, 4:00 AM, and 5:00 AM. For more information, see
“About Auto Receive.”
•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.”
Important!
• Position the watch as shown in the nearby illustration, with its 12 o’clock side facing
towards a window. Make sure there are no metal objects nearby.

• Proper signal reception can be difficult or even impossible under the conditions listed
below.
• Signal reception is normally better at night than during the day.
• Time calibration signal reception takes from two to six minutes. Take care that you
do not perform any button operations or move the watch during this time.

• This watch is able to receive the time calibration signal
transmitted from Mainflingen, Germany (located 25
kilometers southeast of Frankfurt). Signal reception is
possible within the area represented by a circle with a
radius of about 1,000 kilometers.
• At distances further than about 500 kilometers, the
signal may become weak and reception may be
impossible under certain conditions.
• Signal reception may be poor in the shaded area on the
map, even though it is within 1,000 kilometers of the
signal transmitter.
• See the information under “Signal Receive
Troubleshooting” if you experience problems with time
calibration signal reception.

About Auto Receive
When auto receive is turned on, the watch automatically starts to receive the time
calibration signal when the time in the Timekeeping Mode reaches 2:00 AM, 3:00 AM,
4:00 AM, and 5:00 AM each day (calibration times).
Note
• The auto receive operation is performed only if the watch is in the Timekeeping
Mode or World Time Mode when one of the calibration times is reached. It is not
performed if a calibration time is reached while an alarm is sounding, or while you
are making settings (while settings are flashing on the display).
• Auto receipt of the calibration signal is designed to be performed early in the
morning, while you sleep (provided that the Timekeeping Mode time is set correctly).
Before going to bed for the night, remove the watch from your wrist, and put it in a
location where it can easily receive the signal.
• When auto receive is turned on, the watch receives the calibration signal for two to
six minutes everyday when the time in the Timekeeping Mode reaches each of the
four calibration times. Do not perform any button operation within six minutes before
or after any of the four calibration times. Doing so can interfere with correct
calibration.
• Remember that reception of the calibration signal depends on the time kept in the
Timekeeping Mode.The receive operation is performed whenever the display shows
one of the four calibration times, regardless of whether or not the Timekeeping Mode
time is actually the correct time.
• When two, three, or four receptions are successful, the watch uses the data of the
last reception for calibration.When only one reception is successful, the watch uses
the data of the successful reception.
About the Receiving Indicator
The receiving indicator shows the strength of the calibration signal being received. For
best reception, be sure to keep the watch in a location where signal strength is
strongest.

Problem
Cannot perform
manual receive.
Auto receive is
turned on, but
the receiving
indicator (Level
4) does not
appear on the
display.
Probable Cause
• The watch is not in the Timekeeping Mode.
•Your current Home City is not one of the
following city codes:
BER, PAR, LON, or ATH.
•You changed the time setting manually.
•The watch was not in the Timekeeping
or World Time Mode, or you were
performing some button operation
during the auto receive operation.
• Even if receive is successful, the
receiving indicator (Level 4) disappears
every day at 3 am.
What you should do
•Enter the Timekeeping Mode
and try again.
•Select BER, PAR, LON, or
ATH as your Home City.
•Perform manual signal receive
or wait until the next auto
signal receive operation is
performed.
•Check to make sure the watch
is in a location where it can
receive the signal.
Time setting is
incorrect
following signal
reception.
•Time data (hour, minutes, seconds) only
was received during the last receive
operation. The receiving indicator (Level
4) appears only when time data and
date data (year, month, day) are both
received.
•If the time is one hour off, the DST
setting may be incorrect.
•The Home City code setting is not
correct for the area where you are using
the watch.
•Change the DST setting to
Auto DST.
•Select the correct Home City
code.
• Even in an area where signal strength is strong, it takes about 10 seconds for signal
reception to stabilize enough for the receiving indicator to indicate signal strength.
• Use the receiving indicator as a guide for checking signal strength and for finding the
best location for the watch during signal receive operations.
• The receiving indicator (Level 4) remains on the display in all modes following
reception of the time calibration signal and calibration of the watch’s time setting.
The receiving indicator (Level 4) is not displayed if signal reception was
unsuccessful or after manual adjustment of the current time setting.
• The receiving indicator (Level 4) is displayed only when the watch is able to
successfully receive both time and date data. It does not appear when only time data
is received.
• The receiving indicator (Level 4) indicates that at least one of the four calibration
signal receive operations was successful. Note, however, that the receiving indicator
(Level 4) is cleared from the display at 3:00 AM each day.
To perform manual receive
1. Place the watch on a stable surface so its top (12
o’clock side) is facing towards a window.
• Note that signal reception is poor if the watch is on its
back or side.
2. In the Timekeeping Mode, hold down Dfor about two
seconds until the watch beeps.
3. Release Dand the current time flashes to indicate that
signal reception has started.
• Time calibration signal reception takes from two to six

Standard Time. Remember that not all countries or even local areas use Daylight
Saving Time.
The time calibration signal transmitted from Mainflingen includes both Standard Time
and DST data. When the DST setting is turned on, the watch switches between
Standard Time and DST (summer time) automatically in accordance with the
Mainflingen signal.
• The default DST setting is Auto DST (A) whenever you select BER, PAR, LON,
or ATH as your Home City code.

Reference
This section contains more detailed and technical information about watch operation.
It also contains important precautions and notes about the various features and
functions of this watch.
Auto return features
• If you leave the watch in the Alarm, Data Memory, or Hand Setting Mode for two or
three minutes without performing any operation, it automatically changes to the
Timekeeping Mode.
• If you leave the watch with a flashing setting or cursor on the display for two or three
minutes without performing any operation, it automatically saves any settings you
have made up to that point and exits the setting screen.
Scrolling
The A, B, and Dbuttons are used in various modes and setting screens to scroll
through data on the display. In most cases, holding down these buttons during a scroll
operation scrolls through the data at high speed.
Initial Screens
When you enter the World Time, Alarm, or Date Alert Mode, the data you were
viewing when you last exited the mode appears first.
Time Calibration Signal Reception Precautions
• Strong electrostatic charge can result in the wrong time being set.
• Even when the watch is within the reception range of the transmitter, signal
reception is impossible if the signal is blocked by mountains or other geological
formations between the watch and signal source.
• Signal reception is affected by weather, atmospheric conditions, and seasonal
changes.
• 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.
• Even if the time calibration signal is received properly, certain conditions can cause
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.
• The watch is designed to automatically update the date and day of the week for the
period January 1, 2000 to December 31, 2039. Setting of the date by the time
calibration signal cannot be performed starting from January 1, 2040.
• 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.
• When all four auto receptions are successful (2:00 AM, 3:00 AM, 4:00 AM, and 5:00
AM), the watch uses the data of the last reception for calibration. When only one
reception is successful, the watch uses the data of the successful reception.
• Normally, the signal reception date shown by the Last Signal screen is the date data
included in the received time calibration signal.When only time data is received,
however, the Last Signal screen shows date as kept in the Timekeeping Mode at the
time of signal reception.

• If you are in an area where proper time calibration signal reception is impossible, the
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.The following are the initial factory defaults for these
settings.
Timekeeping
• Resetting the seconds to 00 while the current count is in the range of 30 to 59
causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are
reset to 00 without changing the minutes.
• The day of the week is automatically displayed in accordance with the date (year,
month, and day) settings.
• The year can be set in the range of 2000 to 2039.
• The watch’s built-in full automatic calendar makes allowances for different month
lengths and leap years. Once you set the date, there should be no reason to change
it except after you have the watch’s battery replaced.
• The current time for all city codes in the Timekeeping Mode and World Time Mode is
calculated in accordance with the Greenwich Mean Time (GMT) differential for each
city, based on your Home City time setting.
• GMT differential is calculated by this watch based on Universal Time Coordinated
(UTC*) data.
* The letters “UTC”stands 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. The reference point for UTC is
Greenwich, England.

12-hour/24-hourTimekeeping Formats
The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is also
applied in all other modes.
• With the 12-hour format, the P(PM) indicator appears on the display for times in the
range of noon to 11:59 p.m. and no indicator appears for times in the range of
midnight to 11:59 a.m.
• With the 24-hour format, times are displayed in the range of 0:00 to 23:59. The
indicator 24 indicates the 24-hour format.
Backlight Precautions
The backlight uses an EL (electro-luminescent) panel that causes the entire display to
glow for easy reading in the dark.
In any mode, press Bto illuminate the display for about one second.
• The electro-luminescent panel that provides illumination loses power after very long
use.
• The illumination provided by the backlight may be hard to see when viewed under
direct sunlight.
• The watch may emit an audible sound whenever the display is illuminated. This is
due to vibration of the EL panel used for illumination, and does not indicate
malfunction.
• The backlight automatically turns off whenever an alarm sounds.
• Frequent use of the backlight shortens the battery life.
