The power supply of this watch uses a solar cell to generate
electrical power, which is stored by a rechargeable battery. Using
or storing the watch where it is not regularly exposed to light, or
allowing it to be blocked from light by your sleeve for long periods
as you are wearing it can cause the power of the rechargeable
battery to run down. To ensure stable operation, be sure to allow
the watch to be exposed to light as much as possible when you
are wearing or storing it.
Important!
Note that all data in memory and all settings are cleared whenever
you allow the level of the rechargeable battery to drop to Level 4.

should wait for a short while after charging to check the battery
level indicator.
•When the battery level approaches Level 3, the digital display will
start to flash and the analog hands will move to the 12 o’clock
position.
•Even after the battery drops to Level 4, you will be able to resume
normal operation by charging the battery.
•When charging from Level 4, the digital display will start operating
when the battery reaches Level 3. At this time, you will be able to
configure digital time and date settings only. The analog hands will
start to operate when the battery reaches Level 2. At that time,
adjust the analog hand setting so it matches the digital time.
•When charging the battery, keep the watch exposed to light until
the battery reaches Level 2 or Level 1.
❚ Start charging at Level 3!
Battery Level 3 indicates that remaining battery power is very low.
Be sure to expose the watch to light for recharging as soon as
possible after the Level 3 indicator starts to flash.
❚ Flashing Recover Indicator
If you use the light or alarms a number of times during a short
period, a recover (R) indicator flashes on the display and the
following operations become disabled as battery power recovers.

Required Daily Charging Time
• The following is the daily amount of
charging required each day to support
the operations under “Daily Use”.
Power Saving causes the watch to automatically enter a sleep state and save power whenever the watch is left in the dark. The Power
Saving feature of the watch is turned on at the factory.
•Note that the watch may also enter the sleep state if the watch is blocked from light by your sleeve.
❚ How the sleep state works
Display sleep state
The display sleep state is triggered whenever the watch is left in the
dark for about one hour between the times of 10:00 p.m. and 6:00 a.m.
•The display sleep state causes the display to go blank, except for
a flashing Power Saving indicator. Alarms and the hourly time
signal continue to operate normally while the watch is in the
display sleep state. Even when the watch is in the display sleep
state, digital-analog time coordination and auto signal receive are
both performed.
• The watch will not enter the sleep state if it is in the Stopwatch Mode.
Function sleep state
The function sleep state is triggered whenever the watch is left in
the dark for six or seven days.
•Alarms and the hourly time signal are disabled while the watch is
in the function sleep state. In the function sleep state, the analog
hands remain stopped at the 12 o’clock position, and auto signal
receive is not performed.
•Digital timekeeping functions continue to operate normally in the
function sleep state.
Power Saving
Indicator
❚ To recover from the sleep state
Move the watch to a brightly lit location or press any button. The
watch will also recover from the sleep state if you angle it towards
your eyes for reading (see “To illuminate the face with the auto
light switch”).
•It can take up to two seconds before display figures re-appear
after you place the watch in a well-lit area.
❚ To turn Power Saving on and off
Use the procedure under “To configure home time settings” to turn
Power Saving on or off.
Leaving the watch in a drawer or anywhere else it is dark can
cause Power Saving to trigger in order to conserve battery
power.
Power Saving
An LED light is used to illuminate the face of the watch for easy
reading in the dark. An auto light switch automatically illuminates
the face when you angle the watch towards your eyes for reading.
❚ To illuminate the face manually
Press the BB
BB
Bbutton in any
mode to illuminate the face of
the watch.
•You can use the procedure under
“Specifying the Illumination
Duration” to configure the
illumination duration as
approximately 1.5 seconds or 3
seconds.
•Pressing the Bbutton illuminates the face regardless of whether
the auto light switch is on or off.
You may hear a faint rattling sound when you move the watch
around. This sound is caused by the movement of a metal
bulb that controls operation of the auto light switch, and does
not indicate malfunction.
❚ To illuminate the face with the auto light
switch
The auto light switch automatically illuminates the face
whenever you angle the watch towards your eyes for reading,
but only when it is dark.
•The auto light switch does not illuminate the face when
surrounding light is bright.
You can use the procedure under “Specifying the Illumination

may not operate properly if the angle is
greater.
Important!
•The light may be difficult to see if you turn it on under bright
sunlight.
•If you press the Bbutton or if an alarm operation starts while the
face is illuminated, illumination will turn off.
Auto Light Precautions
•Frequent use of the auto light can run down the battery.
•The auto light switch may cause the face to illuminate when your
sleeve covers the display of the watch.
•The face may not illuminate immediately when you angle the
watch towards your face. This does not indicate malfunction.
•The face remains illuminated for the currently set duration (1.5 or
3 seconds) only, even if you leave the watch angled towards your
face.
•The auto light switch is automatically disabled whenever battery
power is at Level 3 or lower.
•The face may illuminate unintentionally when you wear the watch
on the inside of your wrist, when you shake your arm, or when
you raise your arm. Be sure to turn off the auto light switch
whenever you do not need illumination.
•Keep the auto light switch turned off whenever you are wearing
the watch on the inside of your wrist.
•Electro-static charge and magnetism can interfere with auto light
operation and even make operation impossible. If this happens
lower your arm to the starting position and then raise it again. If
you still have trouble with illumination, try lowering your arm down
to your side and then raise it to your face for reading.
•The auto light switch is automatically disabled when the watch is
in the Hand Setting Mode.
Rotate your arm so the watch
is angled at about 40 degrees,
so you can read its face.

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 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.
Note that transmission of the standard wave may be
interrupted occasionally due to maintenance, lightening, etc.
How a Radio-controlled Watch Works
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.

that the wave is relatively weak at distances greater than
1,000km, so reception may be poor at long distances.
•Geographic contours, nearby buildings, seasonal conditions, 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.
Near high-voltage lines
Among or near buildings
Receiving the Calibration Signal
There are two methods you can use to receive the time calibration signal.
•Auto receive (Reception is performed automatically at
midnight, 1:00, 2:00, 3:00 and 4:00 each morning.)
•Manual receive (You initiate reception using a button
operation.)
•If reception is not successful for any of the normal auto receive
operations shown above, auto receive is performed one more
time at 5:00 a.m.
•The watch is set up for auto receive at the factory, so all you need to
do is to place it in a location that allows good reception each night.
❚ To position the watch for optimum 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.

Calibration Signal Reception
Precautions
•Auto reception can be performed while the watch is in the
Timekeeping Mode or World Time Mode only.
•When a time calibration signal is received, the watch corrects its
digital time setting first, and then adjusts the analog time setting
accordingly. In order to ensure that the analog time matches the
digital time, make sure you adjust the analog time to match the
digital time before signal reception is performed.
•Pressing 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, seasonal conditions,
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. It operates like a standard (non-radio
controlled) watch outside of the range 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
±15 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 2099.
Attempting a receive operation after that causes an error.

Troubleshooting
The watch cannot receive the time calibration signal.
•Is the signal being transmitted?
Though the Japanese calibration signal (Call Sign: JJY) is
continually transmitted by the National Institute of Information and
Communications Technology (NICT) in theory, it may sometimes
be interrupted for periodic maintenance work, or because of
lightening or other problems.
•Are you within the reception range of a transmitter?
See “Reception Range” for information about areas where the
watch can receive the 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.
•Do you have the correct Home City code selected?
Remember that auto receive is not performed unless TYO
(Japan), NYC (New York), CHI (Chicago), DEN (Denver), or LAX
(Los Angeles) is selected as the Home City. Select the correct
Home City code using the procedure under “To configure home
time settings”.
•Is auto receive turned off (OFF)?
Use the procedure under “Configuring Auto Receive Settings” to
turn on auto receive.
•Is the watch in any mode other than the Timekeeping Mode or
World Time Mode during the auto receive times (midnight, 1:00
a.m., 2:00 a.m., 3:00 a.m., 4:00 a.m., and 5:00 a.m.)?
Auto receive is performed only when the watch is in the
Timekeeping Mode or World Time Mode. It is not performed if the
watch is in any other mode.
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 slightly off (within one
second).
Time calibration signal reception is successful, but the current
time is one hour fast.
•Do you have summer time (DST) turned on (ON)?
Use the procedure under “To configure home time settings” to turn
off summer time.
Time calibration signal reception is successful, but the current
time setting is wrong.
•Is the correct city code selected for your Home City?
If you are in Japan, you should have TYO selected for your Home
City. For other areas, select the correct Home City code using the
procedure under “To configure home time settings”.
World time lets you display the current time in any one of 30 cities
(29 time zones) around the world.
•When you enter the World Time Mode, the screen for the city that
was displayed when you last exited the mode appears first.
•The seconds count in the World Time Mode is linked with the
Timekeeping Mode seconds count.
•The same 12-hour/24-hour format you select for the Timekeeping
Mode time is also applied in the World Time Mode.
Important!
