Bright Light
Solar cell
The electricity generated by the solar cell of the watch is
stored by a rechargeable battery. Leaving or using the
watch where it is not exposed to light causes the battery
to run down. Make sure the watch is exposed to light as
much as possible.
• When you are not wearing the watch on your wrist,
position the face so it is pointed at a source of bright
light.
• You should try to keep the watch outside of your sleeve
as much as possible. Charging is reduced significantly if
the face is covered only partially.
• The watch continues to operate, even when it is not exposed to light. Leaving the
watch in the dark can cause the battery to run down, which will result in some watch
functions to be disabled. If the battery goes dead, you will have to re-configure watch
settings after recharging. To ensure normal watch operation, be sure to keep it
exposed to light as much as possible.

Radio-controlled Atomic Timekeeping
This watch receives a time calibration signal and updates its time setting accordingly.
• This watch is designed to pick up the time calibration signals transmitted in Germany
(Mainflingen), England (Anthorn), the United States (Fort Collins), China (Shangqiu),
and Japan (Fukushima, Fukuoka/Saga).
Current Time Setting
This watch adjusts its time setting automatically in accordance with a time calibration
signal. You also can perform a manual procedure to set the time and date, when
necessary.
• The first thing you should do after purchasing this watch is to specify your
Home City (the city where you normally will use the watch). For more
information, see “To specify your Home City”.
• When using the watch outside the areas covered by the time signal transmitters, you
will have to adjust the current time setting manually as required. See “Timekeeping”
for more information about manual time settings.
• The U.S. time calibration signal can be picked up by the watch while in North
America. The term “North America” in this manual refers to the area that consists of
Canada, the continental United States, and Mexico.
• As of December 2009, China does not use Daylight Saving Time (DST). If China
does go to the Daylight Saving Time system in the future, some functions of this
watch may no longer operate correctly.
• Using this watch in a country covered by a time calibration that is different from the
countries it supports may result in incorrect time indication due to local application of
summer time, etc.

• Normally, your watch should show the correct time as soon as you select your Home
City code. If it does not, it should adjust automatically after the next auto receive
operation (in the middle of the night). You also can perform manual receive or you
can set the time manually.
• The watch will receive the time calibration signal automatically from the applicable
transmitter (in the middle of the night) and update its settings accordingly. For
information about the relationship between city codes and transmitters, see
“Important!” under “Time Calibration Signal Reception” and “Transmitters”.
• See the maps under “Approximate Reception Ranges” for information about the
reception ranges of the watch.
• You can disable time signal reception, if you want. See “To turn auto receive on and
off” for more information.
• Under factory default settings, auto receive is turned off for all of the following city
codes: MOW (Moscow), HNL (Honolulu), and ANC (Anchorage). For details about
turning on auto receive for these city codes, see “To turn auto receive on and off”.
Time Calibration Signal Reception
There are two different methods you can use to receive the time calibration signal:
auto receive and manual receive.
• Auto Receive
With auto receive, the watch receives the time calibration signal automatically up to
six times a day (five times a day for the Chinese calibration signal). When any auto
receive is successful, the remaining auto receive operations are not performed. For
more information, see “About Auto Receive”.
• Manual Receive
Manual receive lets you start a time calibration receive operation with the press of a
button. For more information, see “To perform manual receive”.
Important!
• When getting ready to receive the time calibration signal, position the watch as
shown in the nearby illustration, with its 12 o’clock side pointing towards a window.
This watch is designed to receive a time calibration signal late at night. Because of
this, you should place the watch near a window as shown in the illustration when you
take it off at night. Make sure there are no metal objects nearby.

About Auto Receive
The watch receives the time calibration signal automatically up to six times a day
(five times a day for the Chinese calibration signal). When any auto receive is
successful, the remaining auto receive operations are not performed. The reception
schedule (calibration times) depends on your currently selected Home City, and
whether standard time or Daylight Saving Time is selected for your Home City.

• Signal reception normally is better at night than during the day.
• Time calibration signal reception takes from two to seven minutes, but in some
cases it can take as long as 14 minutes. Take care that you do not perform any
button operations or move the watch during this time.

Note
• When a calibration time is reached, the watch will receive the calibration signal only
if it is in either the Timekeeping Mode or World Time Mode. Reception is not
performed if a calibration time is reached while you are configuring settings.
• Auto receive of the calibration signal is designed to be performed early in the
morning, while you sleep (provided that the Timekeeping Mode time is set correctly).
Before going to bed for the night, remove the watch from your wrist, and put it in a
location where it can receive the signal easily.
• The watch receives the calibration signal for two to seven minutes everyday when
the time in the Timekeeping Mode reaches a calibration time. Do not perform any
button operation within seven minutes before or after the calibration times. Doing so
can interfere with correct calibration.
• Remember that reception of the calibration signal depends on the current time in the
Timekeeping Mode. The receive operation will be performed whenever the display
shows any one of the calibration times, regardless of whether or not the displayed
time actually is the correct time.
About the Signal Strength Indicator
The signal strength indicator shows the strength of the calibration signal being
received. For best reception, be sure to keep the watch in a location where signal
strength is strongest. The signal strength indicator is displayed while an auto or
manual receive operation is in progress.

• Even in an area where signal strength is strong, it takes about 10 seconds for signal
reception to stabilize enough for the signal strength indicator to indicate signal
strength.
• Use the signal strength indicator as a guide for checking signal strength and for
finding the best location for the watch during signal receive operations.
• Following reception of the time calibration signal and calibration of the watch’s time
setting, the RCVD indicator will remain on the display in all modes. The RCVD
indicator will not be displayed if signal reception was unsuccessful or after you adjust
the current time setting manually.
• The RCVD indicator is displayed only when the watch is able to receive both time
and date data successfully. It does not appear when only time data is received.
• The RCVD indicator indicates that at least one of the auto calibration signal receive
operations was successful. Note, however, that the RCVD indicator disappears from
the display each day when the first auto receive operation of the day is performed.

This watch is equipped with a solar cell and a rechargeable battery that is charged by
the electrical power produced by the solar cell. The illustration shown below shows
how you should position the watch for charging.
Important!
• Storing the watch for long periods in an area where there is no light or wearing it in
such a way that it is blocked from exposure to light can cause rechargeable battery
power to run down. Be sure that the watch is exposed to bright light whenever
possible.
• This watch uses a rechargeable battery to store power produced by the solar cell, so
regular battery replacement is not required. However, after very long use, the
rechargeable battery may lose its ability to achieve a full charge. If you experience
problems getting the rechargeable battery to charge fully, contact your dealer or
CASIO distributor about having it replaced.
• Never try to remove or replace the watch’s rechargeable battery yourself. Use of the
wrong type of battery can damage the watch.
• All data stored in memory is deleted, and the current time and all other settings
return to their initial factory defaults whenever battery power drops to Level 5 and
when you have the battery replaced.
• Turn on the watch’s Power Saving function and keep it in an area normally exposed
to bright light when storing it for long periods. This helps to keep the rechargeable
battery from going dead.

• The flashing LOW indicator at Level 3 tells you that battery power is very low, and
that exposure to bright light for charging is required as soon as possible.
• At Level 5, all functions are disabled and settings return to their initial factory
defaults. Once the battery reaches Level 2 after falling to Level 5, reconfigure the
current time, date, and other settings.
• The watch’s Home City code setting will change automatically to TYO (Tokyo)
whenever the battery drops to Level 5. With this Home City code setting, the watch is
configured to receive the time calibration signals of Japan. If you are using the watch
in North America, Europe, or China, you will need to change the Home City code
setting to match your location whenever the battery drops to Level 5.
• Display indicators reappear as soon as the battery is charged from Level 5 to Level 2.
• Leaving the watch exposed to direct sunlight or some other very strong light source
can cause the battery power indicator to show a reading temporarily that is higher
than the actual battery level. The correct battery level should be indicated after a few
minutes.
• If you use the light or alarms a number of times during a
short period, all segments of the battery power indicator
flash and the following operations become temporarily
disabled as battery power recovers.
- Display illumination
- Alarm and hourly time signal
- Time calibration signal reception
After some time, the battery power indicator should stop
flashing to indicate that battery power is back to normal.
At this time the watch should return to normal operation.
• If the battery power indicator frequently flashes, it
means that battery power is low. Leave the watch in
bright light to allow it to charge.

Auto light switch on
indicator
This watch has an EL (electro-luminescent) panel that
causes the entire display to glow for easy reading in the
dark. The watch’s auto light switch turns on illumination
automatically when you angle the watch towards your
face.
• The auto light switch must be turned on (indicated by
the auto light switch on indicator) for it to operate.
• See “Illumination Precautions” for other important
information about using illumination.
Solar cell
Example: Orient the watch so its face is
pointing at a light source.
• The illustration shows how to position a
watch with a resin band.
• Note that charging efficiency drops when
any part of the solar cell is blocked by
clothing, etc.
• You should try to keep the watch outside of
your sleeve as much as possible. Charging
is reduced significantly if the face is
covered only partially.

Daylight Saving Time (summer time) advances the time setting by one hour from
Standard Time. Remember that not all countries or even local areas use Daylight
Saving Time.
The time calibration signals transmitted from Mainflingen (Germany), Anthorn
(England), or Fort Collins (the United States) include both Standard Time and DST
data. When the Auto DST setting is turned on, the watch switches between Standard
Time and DST (summer time) automatically in accordance with the signals.
• Though the time calibration signals transmitted by the Fukushima and Fukuoka/
Saga, Japan transmitters include summer time data, summer time currently is not
implemented in Japan (as of 2009).
• The default DST setting is Auto DST (AvtA) whenever you select LIS, LON, MAD,
PAR, ROM, BER, STO, ATH, MOW, TYO, ANC, YVR, LAX, YEA, DEN, MEX, CHI,
MIA, YTO, NYC, YHZ, or YYT as your Home City code.
• If you experience problems receiving the time calibration signal in your area, it
probably is best to switch between Standard Time and Daylight Saving Time
(summer time) manually.

Specifications
Radio-controlled Atomic Timekeeping Precautions
• Strong electrostatic charge can result in the wrong time being set.
• The time calibration signal bounces off the ionosphere. Because of this, such factors
as changes in the reflectivity of the ionosphere, as well as movement of the
ionosphere to higher altitudes due to seasonal atmospheric changes or the time of
day may change the reception range of the signal and make reception temporarily
impossible.
• Even if the time calibration signal is received properly, certain conditions can cause
the time setting to be off by up to one second.
• The current time setting in accordance with the time calibration signal takes priority
over any time settings you make manually.
• The watch is designed to update the date and day of the week automatically for the
period January 1, 2000 to December 31, 2099. Setting of the date by the time
calibration signal cannot be performed starting from January 1, 2100.
• This watch can receive signals that differentiate between leap years and non-leap
years.
• Though this watch is designed to receive both time data (hour, minutes, seconds)
and date data (year, month, day), certain signal conditions can limit reception to time
data only.
• If you are in an area where proper time calibration signal reception is impossible, the
watch keeps the time with the precision noted in “Specifications”.
• If you have problems with proper time calibration signal reception or if the time
setting is wrong after signal reception, check your current city code, DST (summer
time), and auto receive settings.
• The Home City setting reverts to the initial default of TYO (Tokyo) whenever the
battery power level drops to Level 5 or when you have the rechargeable battery
replaced. If this happens, change the Home City to the setting you want.
Transmitters
The time calibration signal received by this watch depends on the currently selected
Home City code.
• When a U.S. time zone is selected, the watch receives the time calibration signal
transmitted from the United States (Fort Collins).
• When a Japanese time zone is selected, the watch receives the time calibration
signal transmitted from Japan (Fukushima and Fukuoka/Saga).
• When a European time zone is selected, the watch receives the time calibration
signals transmitted from Germany (Mainflingen) and England (Anthorn).
• When a China time zone is selected, the watch receives the time calibration signals
transmitted from China (Shangqiu City).
• When your Home City is LIS, LON, MAD, PAR, ROM, BER, STO, ATH, or MOW
(which can receive both the Anthorn and Mainflingen signals), the watch first tries
to pick up the signal it last successfully received. If that fails, it tries the other signal.
For the first receive after you select your Home City, the watch tries the nearest
signal first (Anthorn for LIS, LON, Mainflingen for MAD, PAR, ROM, BER, STO, ATH,
and MOW).
Auto Return
• If you do not perform any operation for about two or three minutes while a setting
screen (with a flashing setting) is on the display, the watch will exit the setting screen
automatically.
• The watch returns to the Timekeeping Mode automatically if you do not perform any
button operation for two or three minutes in the Alarm Mode.
Scrolling
B and D buttons are used in various modes and setting screens to scroll through
data on the display. In most cases, holding down these buttons during a scroll
operation scrolls at high speed.
Initial Screens
When you enter the World Time Mode or Alarm Mode, the data you were viewing
when you last exited the mode appears first.
Timekeeping
• Resetting the seconds to 00 while the current count is in the range of 30 to 59
causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are
reset to 00 without changing the minutes.
• The year can be set in the range of 2000 to 2099.
• The watch’s built-in full automatic calendar makes allowances for different month
lengths and leap years. Once you set the date, there should be no reason to change
it except when battery power drops to Level 5.
• The current time for all city codes in the Timekeeping Mode and World Time Mode is
calculated in accordance with the Coordinated Universal Time (UTC) for each city,
based on your Home City time setting.

• Based on data as of December 2009.
• The rules governing global times (UTC offset and GMT differential) and summer
time are determined by each individual country.
Illumination Precautions
• The electro-luminescent panel that provides illumination loses power after very long
use.
• Illumination may be difficult to see when viewed under direct sunlight.
• The watch may emit an audible sound whenever the display is illuminated. This is
due to vibration of the EL panel used for illumination, and does not indicate
malfunction.
• Illumination turns off automatically whenever an alarm sounds.
• Frequent use of illumination runs down the battery.
Auto light switch precautions
• Avoid wearing the watch on the inside of your wrist. Doing so causes the auto light
switch to operate when it is not needed, which shortens battery life. If you want to
wear the watch on the inside of your wrist, turn off the auto light switch feature.
More than 15 degrees
too high
• Illumination may not turn on if the face of the watch is
more than 15 degrees above or below parallel. Make
sure that the back of your hand is parallel to the ground.
• Illumination turns off after a preset amount of time (1.5
seconds), even if you keep the watch pointed towards
your face.
• Static electricity or magnetic force can interfere with proper operation of the auto
light switch. If illumination does not turn on, try moving the watch back to the starting
position (parallel with the ground) and then tilt it back toward you again. If this does
not work, drop your arm all the way down so it hangs at your side, and then bring it
back up again.
• Under certain conditions, illumination may not turn on until about one second after
you turn the face of the watch towards you. This does not necessarily indicate
malfunction of the auto light switch.
• You may notice a very faint clicking sound coming from the watch when it is shaken
back and forth. This sound is caused by mechanical operation of the auto light
switch, and does not indicate a problem with the watch.
