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 time zone that corresponds to the UTC offset of
–
3.5 hours. Because of this, the radio-controlled timekeeping and World Time
functions will not display the correct time for Newfoundland, Canada.
Caution!
Your watch is shipped with its Auto Display feature (which continually changes the
contents of the digital display) turned on. Calibration signal reception is disabled while
Auto Display is turned on.
Press any button to turn off Auto Display and return to the Timekeeping Mode.
About This Manual
• 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

Radio-controlled Atomic Timekeeping
• 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 can also 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 “Home
City Codes and Transmitters”.
This watch receives a time calibration signal and updates
its time setting accordingly.
• Supported time calibration signals: United States (Fort
Collins), England (Anthorn).
• See the information under “Signal Reception
Troubleshooting” if you experience problems with time
calibration signal reception.

Under factory default settings, auto receive is turned off for all of the following city
codes: HNL (Honolulu), ANC (Anchorage), ATH (Athens), and MOW (Moscow). For
details about turning on auto receive for these city codes, see “To turn auto receive
on and off”.
• You can disable time signal reception, if you want. See “To turn auto receive on and
off” for more information.
This watch adjusts its time setting automatically in
accordance with a time calibration signal. You can also
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”.
• See the maps under “Approximate Reception Ranges” for information about the
reception ranges of the watch.
(Hour : Minutes Seconds)
• If you are in an area that does not use Daylight Saving Time (summertime), turn off
the DST setting.
• 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.
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. When any auto receive is successful, the remaining auto receive
operations are not performed. For more information, see “About Auto Receive”.

Setting the Time and Date
Make sure you select your Home City code before you change the current time

• The display of the watch is blank while an auto receive operation is in progress.
• Strong electrostatic charge can result in the wrong time being set.
• The time calibration signal is bounced 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.

• The current time setting in accordance with the time calibration signal takes priority
over any time settings you make.
• 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 a 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.
• Normally, the signal reception date shown by the Last Signal screen is the date data
included in the received time calibration signal. When only time data is received,
however, the Last Signal screen shows the date as kept in the Timekeeping Mode at
the time of signal reception.
• If you are in an area where proper time calibration signal reception is impossible, the
watch keeps 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 following are the initial factory defaults for
these settings.

probably is best to switch between Standard Time and Daylight Saving Time (summer
time) manually.
• 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

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.
Illumination
This watch has an EL (electro-luminescent) panel that causes the entire display to
glow for easy reading in the dark. In any mode (except when a setting screen is on the
display), press
to illuminate the display for about three seconds
.
B
Illumination Precautions
• The electro-luminescent panel that provides illumination loses power after very long
use.
• Illumination may be hard 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.
