What is a radio-controlled watch?
Your radio-controlled watch is designed to receive a time
calibration signal that contains standard time data and adjust its
current time setting accordingly.
Signal is received using
built-in antenna.
Watch decodes
received data and
converts it to time
data.
Time is adjusted
according to time
data.

Watch
Time data
After the watch receives the Standard Time signal, it
performs internal calculations to determine the current time.
Because of this, there may be an error of up to one second
in the displayed time.
Calibration Signal
•The Japanese calibration signal (Call Sign: JJY) is maintained by
the independent Japan Ministry of Posts and Telecommunications
Communication Research Laboratory (CRL). It is a long wave
signal transmitted 24 hours a day from the Mt. Otakadoya
transmitter (40kHz) located in Tamura-gun, Fukushima Prefecture,
and from the Mt. Hagane transmitter (60kHz) located on the
border between Saga Prefecture and Fukuoka Prefecture.
•The U.S. calibration signal (Call Sign: WWVB) is transmitted by
the National Institute of Standards and technology from Fort
Collins, Colorado.
Though the calibration signal is normally transmitted 24 hours
a day, transmission may be interrupted occasionally due to
maintenance, lightening, etc.
Reception Range
This watch is designed to receive the standard time calibration signal of Japan (JJY) or of the United States (WWVB). The signal that is
received depends on the current Home City setting.
•For information about selecting a Home City, see “To set the time and date manually”.

•Under optimum conditions, the calibration signal should be
receivable up to 1,000 kilometers from the transmitter.
•Note that the wave is relatively weak at distances greater than
500km, so reception may be poor at long distances.

How a Radio-controlled Watch Works
Receiving the Calibration Signal
There are two methods you can use to receive the time calibration
signal.
•Auto reception (Reception is performed automatically at 2:00,
3:00, 4:00, and 5:00 each morning.)
•Manual receive (You initiate reception using a button operation.)
•The watch is set up for auto reception at the factory, so all you
need to do is to place it in a location that allows good reception
each night.
❚ Setting Up to Make Reception Easier
Remove the watch from your wrist and place it somewhere so its
top (12 o’clock side, where the antenna is located) is facing
approximately in the direction of the signal transmitter. Keep it
away from metal objects.
Resin band
Metal band
•Orienting the watch so it is sideways to the transmitter makes it
more difficult to receive the signal.
•Do not move the watch while it is receiving the calibration signal.
❚ Time Required for Reception
Signal reception takes anywhere from about two to six minutes.
•Note that when “A/T” (auto) is specified as the transmitter mode,
signal reception can take up to 12 minutes.
•See “To specify the transmitter mode” for more information.
❚ To trigger reception manually
Hold down the DD
DD
D button for
about two seconds.
•The watch beeps and reception starts.
The current time digits flash and the
receive icon changes to “ ” while a
signal receive operation is in progress.
❚ To stop signal reception
Press the DD
DD
D button.
•All other buttons besides D are disabled during signal reception.
When reception is successful
The watch terminates reception and adjusts the current time. Next
it beeps and then displays the date and time the adjustment was
performed.
•The “ ” icon on the display also indicates successful signal
reception.
When reception fails
The watch does not adjust its current time setting, and displays
“ERR” instead.
•The display will return to the normal timekeeping screen automatically
if you do not perform any operation for about one or two minutes.
❚ Receive icon
The receive indicator cycles from
“Unstable” through “Stable” as
shown below while reception is in
progress. How far it cycles depends
on the signal strength.
Keep the watch in a location where
reception is stable while reception is
in progress.
Unstable Stable
•Even under optimum reception conditions, it can take about
10 seconds for reception to stabilize.
•Use the receive icon to check reception status and to
determine the best location for signal reception.
•Note that weather, the time of day, surroundings, and other
factors can all affect reception.
Receive icon
Location
Reception is difficult and may even be impossible in the locations
described below. Avoid such locations when performing signal
reception.
•You should think of your watch operating like a radio or TV when it
is receiving the calibration signal.
If you are experiencing problems with reception, move away
from the types of locations described above to a location with
better reception, and try again.
Near high-voltage lines
Among or near buildings
Near mountains
Inside a vehicle
(automobile, train, plane, etc.)
In a location where there is radio
interference
(construction site, airport, etc.)
Next to a household appliance
or office equipment
(TV, speaker, fax, PC, mobile
phone, etc.)
•Geographic contours, nearby buildings, the season, the time of day, can even make reception impossible even when you are within range of
the transmitter.
•Best reception is possible late at night.

•If only hour, minute, and second data (no date data) is received,
the last reception date shows the date that the receive operation
was performed (as kept in the Timekeeping Mode).
Calibration Signal Reception
Precautions
•Auto reception can be performed while the watch is in the
Timekeeping Mode or World Time Mode only.
•Receipt of a calibration signal causes the digital time to be
adjusted first, followed by adjustment of the analog time. In
order to ensure correct correction of the analog time, be sure to
match the analog time with the digital time before performing a
signal receive operation.
•Note that analog timekeeping is not performed during signal reception,
so the time indicated by the analog hands may be wrong.
•Operating any button while auto reception is in progress will
cause the watch to beep and then exit the receive operation.
•Make sure you are within the range of the calibration signal
transmitter before performing the reception operation.
Remember that geographic contours, nearby buildings, the
season, the time of day, can even make reception impossible
even when you are within range of the transmitter.
•Proper reception may be impossible if there is something
blocking the signal. If reception is unsuccessful, try again.
•This watch is designed to adjust its current time setting in
accordance with the calibration signal transmitted in Japan and
the United States only. Note that you will need to make your
own adjustments when using this watch outside of Japan or the
United States, or in any area that is outside the range of one of
the receivable time calibration signal transmitters.
•When the watch is unable to adjust its time signal using the
calibration signal for some reason, timekeeping accuracy is
within ±20 seconds per month.
•Strong electrostatic charge can cause timekeeping error.
•Signal reception is cancelled if an alarm starts to sound while it
is being performed.
•The watch’s calendar shows dates up to the year 2039.
Attempting a receive operation after that causes an error.
4. When the city code you
want is displayed, press

(Three times)
•Make sure that the watch is in the
Timekeeping Mode or World Time Mode
during the auto reception times.
•Note that manual reception also clears
the “ ” icon from the display.
Time setting is incorrect following signal reception.
Cause: •Summer time is turned on or the wrong
Home City is selected.
Corrective Measures: •If the time is advanced by one hour, it
probably means that summer time
(indicated by the DST indicator on the
display) is turned on.
If the time is off by more than one hour, it
probably means that the Home City is
selected. Correctly configure the summer
time and Home City settings as detailed
under “To set the time and date
manually”.
If you cannot receive the calibration signal or if the current time
setting is incorrect after signal reception, check the current setup
of the watch.
•The following are the watch’s factory default settings, which are
configured automatically whenever you have the battery of the
watch replaced.
Troubleshooting
Cannot perform manual reception.
Cause: •Manual receive can be performed in the
Timekeeping Mode only.
•The Home City is set to a city other than
TYO (Tokyo), NYC (New York), CHI
(Chicago), DEN (Denver), or LAX (Los
Angeles).
Corrective Measures: •Perform manual receive in the
Timekeeping Mode.
•Change Home City to TYO (Tokyo), NYC
(New York), CHI (Chicago), DEN
(Denver), or LAX (Los Angeles). For
details, see “To set the time and date
manually”.
The “ ” icon is not on the display even though auto signal
reception is turned on.
Cause: •The “ ” icon appears after the
watch successfully receives the
calibration signal and adjusts the current
time setting.
•A single receive operation was not
successful.
•The “ ” icon is displayed only when both
the hour-minute-second group and year-
month-day group were received. It will not
remain on the display if only the hour-
minute-second group is received.
•The watch is not in the Timekeeping
Mode or World Time Mode when an auto
reception time is reached.
Corrective Measures: •Check to make sure the watch is in a
location where it can receive the signal.
•Place the watch in a location where
reception conditions are good.
