Getting Acquainted
Congratulations upon your selection of this CASIO watch. To get the most out of your
purchase, be sure to read this manual carefully.
Keep the watch exposed to bright light
The electricity generated by the solar panel of the watch
is stored by a built-in 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 only partially covered.

•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” (page E-12).
•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” (page E-41) for more information about manual time settings.
E-11
•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.
•The analog time of this watch is synchronized with the digital time. Because of this,
the analog time setting is automatically adjusted whenever you change the digital
setting. See “Analog Timekeeping” (page E-48) for more information.
•As of June 2013, 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.
E-12

•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 page
E-17 and “Transmitters” (page E-65).
•See the maps under “Approximate Reception Ranges” (page E-18) 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” on page E-26 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”
on page E-26.
E-14
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
6 times a day (5 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” (page E-21).
• 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” (page E-25).
E-15
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.

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.
E-24
About the Receiving Indicator
The receiving 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 receiving indicator is displayed while an auto or manual receive
operation is in progress.

Daylight Saving Time (DST)
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 2013).
•The default DST setting is Auto DST (AUTO) whenever you select LIS,LON,MAD,
PAR,ROM,BER,STO,ATH,MOW,TYO,ANC,YVR,LAX,YEA,DEN,MEX,CHI,
NYC,YHZ, or YYT as your Home City code.
•If you experience problems receiving the time calibration signal in your area, it is
probably best to switch between Standard Time and Daylight Saving Time (summer
time) manually.
E-47
To change the Daylight Saving Time (summer time) setting
1. In the Timekeeping Mode, hold down Afor about two seconds until the watch
beeps and ADJ appears on the display.
•This will cause the currently selected city code to flash.

Analog Timekeeping
The analog time of this watch is synchronized with the digital time. The analog time
setting is adjusted automatically whenever you change the digital time.
Note
•The hands for the analog timepiece move to adjust to a new setting whenever any
of the following occurs.
When you change the digital time setting manually
When the digital time setting is changed by time calibration signal reception
When you change the Home City code and/or DST setting
•If the analog time does not match the digital time for any reason, use the procedure
described under “To adjust home positions” (page E-49) to match the analog
setting to the digital setting.
•Whenever you need to adjust both the digital and the analog time settings manually,
make sure you adjust the digital setting first.
•Depending on how much the hands have to move in order to adjust to the digital
time, it may take some time before they stop moving.
E-49
Adjusting Home Positions
Strong magnetism or impact can cause the hands of the watch to be off, even if the
watch is able to perform the signal receive operation. If this happens, perform the
applicable home position adjustment procedures in this section.
•Hand home position adjustment is not required if the analog time and digital time
are the same in the Timekeeping Mode.
To adjust home positions
1. In the Timekeeping Mode, hold down Afor about five
seconds. You can release the button after “H-SET”
appears on the display.
•Though “ADJ” will appear on the display after about
two seconds, do not release the button yet. Keep it

•If the hour and minute hands are out of position, use the D(+) and B(–)
buttons to adjust them.
•Holding down either the D(+) or B(–) button will cause the minute hand
to move at high speed, even if you release the button. High-speed hand
movement will continue until you press either button. High-speed hand
movement started with the Dbutton will also stop automatically after 12
revolutions, while one started with the Bbutton will stop automatically after
one revolution.
2. After everything is the way you want, press Ato return to the Timekeeping Mode.
•After performing home position adjustment, enter the Timekeeping Mode and
check to make sure that the analog hands and the digital display indicate the
same time. If they do not, perform home position adjustment again.

Power Supply
This watch is equipped with a solar panel and a rechargeable battery that is charged
by the electrical power produced by the solar panel. The illustration shown below
shows how you should position the watch for charging.
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 panel 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.
Solar panel
E-52
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
panel, 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.
•The current time and all other settings return to their initial factory defaults whenever
battery power drops to Level 5 (pages E-54 and E-55) and when you have the
battery replaced.
•Turn on the watch’s Power Saving function (page E-60) 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.
E-53
To check the current battery level
In the Timekeeping Mode, press &to display the battery level indicator (page E-8).

E-55
•The flashing indicator at Level 3 and the flashing charge indicator (C) at Level
4 tell 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 or 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.
E-56
•Performing illumination, or beeper operations during a
short period may cause (recover) to appear on the
display.
After some time, battery power will recover and
(recover) will disappear, indicating that the above
functions are enabled again.
•If (recover) appears frequently, it probably means
that remaining battery power is low. Leave the watch in
bright light to allow it to charge.

operation scrolls through the data at high speed.
Initial Screens
When you enter the World Time Mode, the data you were viewing when you last
exited the mode appears first.
E-64
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.
E-65
•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, and DST
(summer time) settings (page E-47), and auto receive settings (page E-26).
•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 (page
E-12).
Transmitters
The time calibration signal received by this watch depends on the currently selected
Home City code (page E-12).
•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).
E-66
•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,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).
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 day of the week is automatically displayed in accordance with the date (year,
month, and day) settings.
•The year can be set in the range of 2000 to 2099.
E-67
•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 after you have the watch’s battery replaced or 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.
12-hour/24-hour Timekeeping Formats
The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is also
applied in all other modes.
•With the 12-hour format, the PM indicator (P) appears on the display for times in the
range of noon to 11:59 p.m. and no indicator appears for times in the range of
midnight to 11:59 a.m.
•With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without
any indicator.
E-68
Illumination Precautions
•Illumination may be hard to see when viewed under direct sunlight.
•Illumination automatically turns off whenever an alarm sounds.
•Frequent use of illumination runs down the battery.
