Before using the watch...
Expose the watch to light.
Your watch runs on electrical power generated from light, which is
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
before using it for the first time. See “Solar Charging” for more
information.
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 “Solar Charging” for more information.

Power Saving
Power Saving causes the watch to enter a sleep state automatically
and stop movement of the analog hands in order to save power
whenever the watch is left in the dark.
The watch will exit the sleep state if you expose it to light or perform
any button operation.
•Though the hands are stopped, the watch continues to keep time
internally.
•Note that the watch also may enter the sleep state and stop if the
solar panel is blocked from light by your sleeve.
Sleep Level 1
Sleep Level 1 is triggered whenever the watch is left in the dark for
about one hour any time between the hours of 10 p.m. and 6 a.m.
In Sleep Level 1:
•The second hand is stopped.
•The hour hand, 24-hour hand, minute hand, and day indicator
continue to operate normally.
•Auto Receive is performed normally.
•Alarms and the hourly time signal continue to operate normally.
Sleep Level 2
Sleep Level 2 is triggered whenever the watch is left in the dark
while in Sleep Level 1 for six or seven days.
In Sleep Level 2:
•The hour hand, 24-hour hand, and minute hand are stopped.
•If the watch reaches Sleep Level 2 while in the World Time Mode,
the hands will move to 12 o’clock and stop when the Home City
time (kept internally) reaches midnight.
•Auto Receive is disabled.
•Alarms and the hourly time signal are disabled.

Solar Charging
Your watch runs on electrical power generated from light, which is
stored by a chargeable battery.
To ensure stable operation, make sure that the watch is exposed to
light as much as possible.
•Whenever you are not wearing the watch on your wrist, position it
so the face (solar cell) is pointed in the direction of a source of
bright light.
Light
Solar cell
Leave the watch under fluorescent lighting, near a window, etc.
•When wearing the watch, try to keep your clothing from blocking
its face, where the solar cell is located.
Charging efficiency is reduced significantly even if the face of the
watch is covered only partially by your sleeve.

How a Radio-controlled Watch Works
What is a radio-controlled watch?
A radio-controlled watch is designed to receive a time calibration
signal that contains standard time data and adjust its current time
setting accordingly.
Cesium
atomic clock
Transmitter Long-wave time
Watch
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 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.
•The U.K. calibration signal (Call Sign: MSF) is transmitted by the
National Physical Laboratory (NPL) from Anthorn, which is located
near Anthorn, Cumbria.
•The German calibration signal (Call Sign: DCF77) is transmitted
by Physikalisch - Technische Bundesanstalt (PTB) in Mainflingen,
which is located southeast of Frankfurt.
•Time calibration signal frequencies and transmitter locations are
subject to change.
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 calibration signal 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.
http://jjy.nict.go.jp
•Note that the above URL is subject to change.
Reception Ranges
The table below shows the time calibration signal that the watch
receives when a particular city code is selected as your Home City.
••
••
•For information about Home City settings, see “Configuring
Home City Settings”. See the “City Code List” for information
about city codes.

•Signal reception is possible in the time zones represented by
HKG (Hong Kong), HNL (Honolulu), and ANC (Anchorage) when
reception conditions are good.
•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 in the nearby maps, 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.
Reception Time
A receive operation can take anywhere from about two to seven
minutes.
•Under certain conditions, a receive operation can take as long as
13 minutes.
Positioning the Watch for Best
Reception
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 the
watch away from metal objects.
Resin band
Metal band
•Orienting the watch so it is sideways to the transmitter makes it
more difficult for the watch to receive the signal.
•Do not move the watch while it is receiving the calibration signal.
Important!
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.
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.
Receiving a Calibration Signal
There are two methods you can use in order to receive the time
calibration signal.
•Auto Receive up to six times per day
•Manual Receive where you hold down the Abutton in the
Timekeeping Mode.
Among or near
buildings
Near high-voltage
lines
Inside an automobile,
train, plane, or other
vehicle
Next to a TV,
speaker, fax,
computer, cellphone,
or other household
appliances or office
equipment
At a construction
site, airport, or other
location where there

Near mountains
Auto Receive
Getting Ready for Auto Receive
You will need to perform the operations described below in order to
use Auto Receive.
•Configure the Home City setting of the Timekeeping Mode so it
matches your current location. The Home City must be in a time
zone where calibration signal reception is supported. See:
“Reception Ranges”and “Configuring Home City Settings”.
•Put the watch into the Timekeeping Mode or World Time Mode.
See: “Modes and Indicators”.
•During the Auto Receive times, position the watch correctly for
best reception. See: “Auto Receive Start Times”(below) and
“Positioning the Watch for Best Reception”.
How Auto Receive Works
Calibration signal reception will start automatically whenever the
current time in the Timekeeping Mode reaches one of the Auto
Receive Start Times listed below. Auto receive can be performed up
to six times a day, but any time a signal receive operation is
successful, no more auto receive operations are performed that day.
Note that the Auto Receive Start Times differ according to the
current Home City setting and the summer time setting.
•Summer time, or Daylight Saving Time (DST) as it is called in
some countries, calls for setting clocks ahead one hour from
standard time during the summer season.
•Note that the start and end of summer time, and whether summer
time is used at all depends on each country.

When reception is successful
After a receive operation is complete, the watch returns to the
Timekeeping Mode, which shows the newly adjusted time.
When reception fails
The watch will return to the Timekeeping Mode without adjusting the
time setting.
Manual Receive
You will need to perform the operations described below in order to
use Manual Receive.
•Configure the Home City setting of the Timekeeping Mode so it
matches your current location. The Home City must be in a time
zone where calibration signal reception is supported. See:
“Reception Ranges”and “Configuring Home City Settings”.
•Put the watch into the Timekeeping Mode. See: “Modes and
Indicators”.
•Position the watch correctly (see “Positioning the Watch for Best
Reception”).
■To start a Manual Receive operation
In the Timekeeping Mode, hold
down the AA
AA
Abutton for about
two seconds until the
indicator hand moves to the
last signal reception result
(“Y”or “N”), and then to
“READY”(“R”for some
models).
•The hour hand, 24-hour hand,
and minute hand continue to
operate normally.
•The second hand will stop at “0”.
While reception is in progress...
•The indicator hand moves to
“WORK”(or “W”for some
models).
•The hour hand, 24-hour hand,
and minute hand will continue to
operate normally.
•Do not perform any watch
operations while signal reception
is in progress (indicator hand at
“WORK”or “W”).
•Under some reception conditions,
the indicator hand may cycle
between “READY”(or “R”) and
“WORK”(or “W”) until reception
stabilizes.
When reception is complete...
•If reception was successful, the
hands will move to the correct
time. After that, the indicator hand
moves to “Y”(or “YES”for some
models). Then after about five
seconds the watch will resume
regular timekeeping.
•If the receive operation fails, the
indicator hand will move to “N”(or
“NO”for some models) and the
hands will move to the unadjusted
time. Then after about five
seconds the watch will resume
regular timekeeping.
■To cancel a manual receive operation
Press any button.
■To check the result of the last receive
operation
In the Timekeeping Mode, press the AA
AA
Abutton.
•The indicator hand will move to “Y”(or “YES”) if the last receive
operation was successful or to “N”(or “NO”) if the last receive
operation was unsuccessful.
•Press the Abutton once to return to normal timekeeping.
•If you do not perform any operation for about five seconds, the
watch will revert automatically to normal timekeeping.
30
N (or NO) when not successful
Y (or YES) when successful
The last receive status changes each time a new time
calibration signal reception operation is performed.
Calibration Signal Reception Precautions
•Auto Receive is not performed while the watch is in the Stopwatch
Mode or Alarm 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 signals transmitted in Japan, the
United States, the U.K., and Germany. Note that you will need to
make your own adjustments when using this watch outside of the
range of the time calibration signal transmitters.
•When the watch is unable to adjust its time using the calibration
signal for some reason, timekeeping accuracy is within ±15
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.
Troubleshooting
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,
electrical noise or objects between you and the transmitter can
interfere with reception. Avoid such areas (see “Positioning the
Watch for Best Reception”) during signal reception.
•Are you within the reception range of a transmitter?
See “Reception Ranges”for information about areas where the
watch can receive the signal.
•Are your Home Time settings configured correctly?
See “Configuring Home City Settings”.
•Is the signal being transmitted?
Transmission of time calibration signals may be interrupted
occasionally due to maintenance, lightning, etc.
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.
•Are your Home Time settings configured correctly?
See “Configuring Home City Settings”.
•If you cannot receive the calibration signal or if the time setting is
incorrect after signal reception, check the 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.
