■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 alarm 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. •Face illumination, •Alarm and hourly time signal •Analog timekeeping •Time calibration signal reception Normal operation will return after the battery recovers. •If the battery drops to Level 3 while the recover indicator is flashing
on the display, the Battery Level Screen will show “”.
■Charging Precautions Avoid charging the watch in the following locations, and anywhere else where the watch may become very hot. •On the dashboard of an automobile parked in the sun •Very close to an incandescent light source or other sources of heat •In a location exposed to direct sunlight for long periods Note that the display panel may become black under very high temperatures. This is temporary, and the display will appear normal again at lower temperatures.
Depending on the light source you are using, the case of the watch may become quite hot during charging. Take care to guard against burn injury after charging.
■To charge the battery Point the solar panel (face) of the watch at a light source. •Remember that even a partial blockage of the solar cell reduces
charging efficiency.
Example: Positioning the watch
Solar Cell
•The illustration shows the resin band model.
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. ■Checking the Battery Level Use the Battery Level Screen to check the current level of the watch’s rechargeable battery. •In the Timekeeping Mode, press the Cbutton once to change to
the Battery Level Screen. To return to the Timekeeping Mode from the Battery Level Screen, press the Cbutton five times.

Digital displays, face illumination, tones (alarm, hourly time signal), time calibration signal reception, and analog timekeeping disabled.
All functions, including timekeeping, disabled.
•Exposing the watch to direct sunlight or other strong light may
cause the battery level indicator to momentarily indicate a level that is higher than the actual battery level. Because of this, you should wait for a short while after charging to check the battery level indicator.
•When the battery level approaches Level 3, the 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 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.

Power Saving
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. •The watch will not enter the sleep state if it is in the Stopwatch Mode. ■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. The alarm 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 sleep state, digital-analog time coordination and time calibration signal auto receive are both performed.
Function sleep state The function sleep state is triggered whenever the watch is left in the dark for six or seven days. •The alarm 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 time
calibration signal auto 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 “Positioning Your Arm Correctly”).
•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.
■Positioning Your Arm Correctly •You should be wearing the watch on the outside of your wrist
when using the auto light switch.
•Make sure that the left (9 o’clock) and
right (3 o’clock) sides of the watch are within ±15 degrees of being parallel
with the ground. The auto light switch 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.
•Face illumination does not work while you are performing a time
calibration signal manual receive operation.
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 face 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 face 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 isangled at about 40degrees, so you can read its face.
With the watch on your wrist, position it level with the ground.

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 data
Cesium
atomic
clock
Transmitter
Internally
Decode
Watch
Time data
Signal is received using built-in antenna.
Watch decodes received data and converts it to time data. Time is adjusted according to time data.
Long- wave time calibration
signal
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
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
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.
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.
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, computer, cell phone, 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 “Configuring Home Time Settings”. For information about city codes, see the “World Time
City Code List”.

Configuring Auto Receive Settings Use the procedure below to turn auto receive of the time calibration signal on or off. When TYO (Tokyo) is selected as your Home City, you can also specify the transmitter selection mode, which controls which Japanese transmitter signal should be used for time calibration. •For information about selecting your Home City, see “Configuring
Home Time Settings”.
•The initial factory default settings for auto receive are Home City =
TYO (Tokyo); Auto Receive = On; Transmitter = AUTO
•The following procedure can be performed only when TYO, LAX,
DEN, CHI, or NYC is selected as the Home City.
■To configure auto receive settings 1. In the Timekeeping Mode,

•All other buttons besides Dare 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 that the adjustment was performed. Reception Error (ERR Indicator) The watch does not adjust its current time setting, and displays “ERR”when signal reception is unsuccessful for some reason. •The watch will return to the Timekeeping Mode automatically if
you do not perform any operation for about one or two minutes.
■Receive Indicator 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 indicator 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 Indicator
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 the 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”.
Using Summer Time (DST) Summer time, or Daylight Saving Time (DST) as it is known in some countries, calls for setting clocks ahead one hour during the summer season. Note that the use of summer time depends on the country and even the local area. ■To turn summer time on or off 1.
In the World Time Mode, use the DD
DD
Dbutton to
display the screen for the city code whose summer time setting you want to change.
2.
Hold down the AA
