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.

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”.
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 facing 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.

Approximate Reception Ranges
1,500 kilometers
Anthorn
500 kilometers
Signal reception may not be possible at the distances noted below during certain
•
times of the year or day. Radio interference may also cause problems with reception
Anthorn (England) transmitter: 500 kilometers (310 miles)
Fort Collins (United States) transmitter: 600 miles (1,000 kilometers)
In April 2007, the U.K. signal transmitter was moved from Rugby to Anthorn, which
•
resulted in a slight shift in the approximate reception range of the signal. The shift is
so slight that there is virtually no change in the ability to receive the signal
Even when the watch is within the reception range of a transmitter, signal reception
•
may be impossible at times due to the effects of geographic contours, structures,
weather, the season of the year, the time of day, radio interference, etc. Note that
the signal becomes weaker at distances of approximately 500 kilometers from the
transmitter, which means that the infl uence of the conditions listed above becomes
even greater
About 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. 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.

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 confi guring 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 each of the calibration times. Avoid
performing any button operation within seven minutes before or after any one of 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.
Calibration signal reception is disabled while a countdown timer operation is in
•
progress.
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.
Receivingindicator
Even in an area where signal strength is strong, it takes about 10 seconds for signal
•
reception to stabilize enough for the receiving indicator to indicate signal strength.
Use the receiving indicator as a guide for checking signal strength and for fi nding 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 Level 3 receiving indicator will remain on the display in all modes. The
Level 3 receiving indicator will not be displayed if signal reception was unsuccessful
or after you adjust the current time setting manually
The Level 3 receiving 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 Level 3 receiving indicator indicates that at least one of the auto calibration
•
signal receive operations was successful. Note, however, that the Level 3 receiving
indicator is cleared from the display when the fi rst auto receive operation of the day
is performed.

Reference
This section contains more detailed and technical information about watch operation.
It also contains important precautions and notes about the various features and
functions of this watch.
Auto Display
Auto Display continually changes the contents of the digital display.
To turn off Auto Display
Press any button to turn off Auto Display. This returns to the Timekeeping Mode.
To turn on Auto Display
In the Timekeeping Mode, while holding down B , hold down D for about two
seconds until the watch beeps.
Note
Calibration signal reception is disabled while Auto Display is being performed.
•
Auto Display cannot be performed while a setting screen is on the display.
•
Button Operation Tone
MUTE indicator
Since the C button is also the mode change button, holding it down to turn the
•
button operation tone on or off also causes the watch’s current mode to change.
The MUTE indicator is displayed in all modes when the button operation tone is
•
turned off.
Auto Return Features
If you leave the watch with the Last Signal screen in the Timekeeping Mode for one
•
or two minutes without performing any operation, it returns to the Current Time and
Date screen in the Timekeeping Mode automatically.
If you leave the watch in the Alarm Mode for two or three minutes without performing
•
any operation, it returns to the Timekeeping Mode automatically.
If you leave the watch with a fl ashing setting on the display for two or three minutes
•
without performing any operation, the watch exits the setting screen automatically.
Scrolling
The B and D buttons are used in various modes and setting screens to scroll
through data. In most cases, holding down these buttons during a scroll operation
scrolls through the data at high speed.
Initial Screens
When you enter the World Time or Alarm Mode, the data you were viewing when
•
you last exited the mode appears fi rst.
Radio-controlled Atomic Timekeeping Precautions
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 refl ectivity 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.
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 “Specifi cations”.
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.
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 displayed automatically in accordance with the date (year,
•
month, and day) settings.
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 after you have the watch’s battery replaced.
The times for the Timekeeping Mode and all the city codes of the World Time Mode
•
are calculated in accordance with each city’s UTC offset.
The UTC offset is a value that indicates the time difference between a reference
•
point in Greenwich, England and the time zone where a city is located.
The letters “UTC” is the abbreviation for “Coordinated Universal Time”, which is the
•
world-wide scientifi c standard of timekeeping. It is based upon carefully maintained
atomic (cesium) clocks that keep time accurately to within microseconds. Leap
seconds are added or subtracted as necessary to keep UTC in sync with the Earth’s
rotation.
The button operation tone sounds any time you press one
of the watch’s buttons. You can turn the button operation
tone on or off as desired.
Even if you turn off the button operation tone, the alarm,
•
Hourly Time Signal, and Countdown Timer Mode alarm
all operate normally.
To turn the button operation tone on and off
In any mode (except when a setting screen is on the
display), hold down C to toggle the button operation tone
on ( MUTE not displayed) and off ( MUTE displayed).

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 B to illuminate the display for about three seconds
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.

Based on data as of June 2007.
•
The rules governing global times (GMT differential and UTC offset) and summer time are determined by
•
each individual country.
* In December 2007, Venezuela changed its offset from –4.0 to –4.5. Note, however, that this watch
displays an offset of –4.0 (the old offset) for the CCS (Caracas, Venezuela) city code.
