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.
• • • • • This watch does not have a city code that corresponds to the UTC offset of
–3.5 hours. Because of this, the radio-controlled atomic timekeeping function
will not display the correct time for Newfoundland, Canada.
Keep the watch exposed to bright light

• 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.

Press A.
• Each press of C cycles through modes in the sequence shown below.
• Stopping at a mode for about one second will cause the display to change to the
data for that mode.
• Operating a button while the hands are moving at high speed may cause the hands
to stop temporarily.
• Except while the watch is performing auto hand home position correction, holding
down C for about two seconds will return directly to the Timekeeping Mode.
Radio-controlled Atomic Timekeeping
This watch receives a time calibration signal and updates its time setting accordingly.
• Supported time calibration signals: Germany (Mainflingen), England (Anthorn), United
States (Fort Collins), China (Shangqiu), and Japan (Fukushima or Fukuoka/Saga)
• See the information under "Signal Reception Troubleshooting" if you experience
problems with time calibration signal reception.
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, which is 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 "Configuring
Time and Date Settings Manually" for more information about manual time settings.

• Normally, your watch should show the correct time as soon as you specify your Home
City code. If it does not, it should adjust automatically after the next auto receive
operation. You also can perform manual receive or you can set the time manually.
• Even if the time calibration signal is received correctly, there are some times when
the analog hands may not indicate the correct time. If this happens, use the
procedures under "Auto Hand Home Position Correction" to check the home
positions of the hands, and make adjustments as required.
Operation Guide 5031
The electricity generated by the solar cell 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. Even if the face of the watch is
blocked only partially from light, charging will be reduced
significantly.

Manual Receive Setting Mode
Check
1. In the Timekeeping Mode, keep A depressed (for
about five seconds) as the second hand moves to the
last signal reception result ("Y" or "N"), then to "READY"
(or "R" for some models), and then to the city code of
the currently selected Home City.
• This indicates the city code setting mode.
2. Use D to move the second hand clockwise to the city
code you want to use as your Home City.
• For information about the Home City, see "Home City
Codes and Transmitters". The watch will receive the
time calibration signal of the transmitter of the
selected city code.
3. After the Home City setting is the way you want, press
A to return to the Timekeeping Mode.
• The actual level at which some functions are disabled depends on the watch model.
• Be sure to read "Power Supply" for important information you need to know
when exposing the watch to bright light.
If the analog hands aren't moving...
If the analog hands aren't moving, it means that the power saving mode has stopped
them to save battery power.
• See "Power Saving" for more information.
• The hands also stop when the watch's battery runs down.

Home City Codes and Transmitters
• The time calibration signal the watch will attempt to pick up depends on its
current Home City code setting as shown below. If you use the watch in Japan or
Europe (each of which has two different transmitter locations), it will try to receive
the time calibration signal from one of the transmitters in your current location. If
it cannot receive the signal, it will then try to receive the time calibration signal
from the other transmitter.

PAR: Paris

• City codes in parentheses indicate areas where reception may be possible only
when conditions are good.
• For full information on city codes, see the "City Code Table".
• In addition to the above, you also can select city codes that are outside the ranges of
the time calibration signal transmitters supported by this watch.
• Note that this watch does not have a city code that corresponds to Newfoundland.
• 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.
• Button operations are indicated using the letters shown
in the illustration.
• Each section of this manual provides you with the
information you need in order to perform operations in
each mode. Further details and technical information
