Before using the watch...
Expose the watch to light
Power Saving
Your watch runs on electrical power generated from light and stored
by a chargeable battery. Long-term storage of the watch can cause
the battery to run low, so be sure to expose the watch to light for
some time before using it for the first time. See “Solar Charging” for
more information.
Power Saving causes the watch to enter a sleep state automatically
and stop movement of the analog hands in order to save power
whenever it is left in the dark. The watch will exit the sleep state if
you expose it to light or perform any button operation.
• Note that the watch may also enter the sleep state and stop if it is
blocked from light by your sleeve.
Low Battery Alert
When secondary battery power is low, the second hand of the watch
will start to jump at 2-second intervals to let you know that charging
is required.
• See “Low Battery Alert” for more information.

How a Radio-controlled Watch Works
Receiving the Calibration Signal
There are two methods you can use in order to receive the time
calibration signal.
What is a radio-controlled watch?
Calibration Signal
Auto Receive
A radio-controlled watch is designed to receive a time calibration
signal that contains standard time data and adjust its current time
setting accordingly.
• The Japanese calibration signal (Call Sign: JJY) is maintained by
the National Institute of Information and Communications
Technology (NICT). It is transmitted 24 hours a day from the Mt.
Otakadoya transmitter (40 kHz) located in Tamura-gun,
Fukushima Prefecture, and from the Mt. Hagane transmitter (60
kHz) 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.
• Time calibration signal frequencies and transmitter locations are
subject to change.
Up to six times per day
(Midnight, 1:00, 2:00, 3:00, 4:00, and 5:00 a.m.)
• As soon as one auto receive is complete, all subsequent auto
receives for that day are cancelled.
Transmitter
Signal is received by
built-in antenna.
Long-wave time

Signal data
Watch decodes
received data and
converts it to time
data.

Time data
Watch
Internally
Time is adjusted
according to 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.
The time data of the Japanese calibration signal (Call Sign:
JJY) is maintained by the Japan Standard Time Group of the
National Institute of Information and Communications
Technology (NICT). Note that transmission of the standard
wave may be interrupted occasionally due to maintenance,
lightning, etc. For more information, visit the website of the
Japan Standard Time Group of the National Institute of
Information and Communications Technology (NICT) at the
following URL.
Manual Receive
You initiate signal reception by pressing a button.
• The indicator hand will indicate
the result of the reception, the
watch will beep, and the indicator
hand will move to “READY”.
In the Timekeeping Mode, press the A button to renter the
Receive Result Mode, which displays the last receive result.
• The indicator hand will move to “Y” (if the last reception was
successful) or “N” (if the last reception was unsuccessful).
• Press the A button to return to the Timekeeping Mode.
• The watch also will return to the Timekeeping Mode automatically
if you do not perform any operation for about five seconds.
Remove the watch from your wrist and place it somewhere so its top
(12 o’clock, where the antenna is located) is facing approximately in
the direction of the signal transmitter. Keep it away from metal
objects.
• The indicator hand will move to “WORK”.
• The hour and minute hands will remain at their normal positions.
• Do not perform any watch operations while signal reception is in
progress.

Press any button.
WORK
When reception is complete (Signaled when the watch beeps.)
• When the receive operation is successful, the indicator hand
moves to “Y”, the watch adjusts its time, and then the indicator
hand returns to its second hand operation after about one or two
minutes.
• When the receive operation fails, the indicator hand moves to “N”
and then the watch returns to the unadjusted time after about one
or two minutes.
Reception Ranges
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 “Changing the Home City Setting”. See the “World Time City Code List” for
information about city codes.

The last receive status changes each time a new time
calibration signal receive operation is performed.
• 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 normally takes anywhere from about two to seven
minutes. Under certain signal conditions however, the receive
operation can take as long at 14 minutes.

Certain conditions can make reception impossible even when the watch is within one of the reception ranges shown above.
Signals become weaker outside of the smaller circles indicated by dashed lines, so the reception environment has a greater effect on signal
reception.
• The following also can affect signal reception: geographic contours, structures, weather, climate, time of day (afternoon, evening), noise.

Operation Guide 4343
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 as operating like a radio or TV
when it is receiving the calibration signal.
Among or near buildings
Inside a vehicle
(automobile, train, plane, etc.)
In a location where there is
radio interference
(construction site, airport, etc.)
Near high-voltage lines
Next to a household
appliance or office
equipment (TV, speaker, fax,
computer, cell phone, etc.)
Calibration Signal Reception
Precautions
Troubleshooting
• Auto receive is disabled while the watch is in the Chronograph
Mode.
• Operating any button while auto receive is in progress will cause
the watch to beep and then exit the receive operation.
• Make sure you are within the range of a calibration signal
transmitter before performing the receive operation. Remember
that geographic contours, nearby buildings, the season, or the
time of day can 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 using the calibration
signal for some reason, timekeeping accuracy is within ±20
seconds per month.
• Strong electrostatic charge can cause timekeeping error.
• Receive is cancelled if an alarm operation starts while it is being
performed.
• The watch’s calendar shows dates up to the year 2099.
Attempting a receive operation after that causes an error.
1. The watch cannot receive the time calibration signal.
• Is there something in the immediate area that may be interfering
with reception?
Even if you are within the reception range of a transmitter, objects
between you and the transmitter or electrical noise can interfere
with reception. Avoid such areas during signal reception. See
“Location” for more information.
• Are you within the reception range of a transmitter?
See “Reception Ranges” for information about areas where the
watch can receive the signal.
• Do you have the correct Home City code selected?
Remember that auto receive is not performed unless TYO
(Tokyo), HKG (Hong Kong), NYC (New York), CHI (Chicago),
DEN (Denver), LAX (Los Angeles), ANC (Anchorage), or HNL
(Honolulu) is selected as the Home City. Select the correct Home
City code using the procedure under “Changing the Home City
Setting”.
• Is the signal being transmitted?
Though the time data of the Japanese calibration signal (Call
Sign: JJY) is maintained by the Japan Standard Time Group of
the National Institute of Information and Communications
Technology (NICT), it sometimes may be interrupted for periodic
maintenance work, or because of lightning or other problems.
2. Time calibration signal reception is successful, but the
hourly time signal and current time are slightly off.
• After the watch receives the time calibration signal, it performs an
internal decoding process before updating its time setting.
Because of this, the time setting may be off slightly (within one
second).
3. Time calibration signal reception is successful, but the
current time setting is wrong.
• Is the correct city code selected for your Home City? Select the
correct Home City code using the procedure under “Changing the
Home City Setting”.
Near mountains
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.
