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 Greenwich
Mean Time differential of –3.5 hours. Because of this, the radio-controlled
atomic timekeeping function will not display the correct time for
Newfoundland, Canada.
Warning!
• The measurement functions built into this watch are not intended for use in taking
measurements that require professional or industrial precision. Values produced
by this watch should be considered as reasonably accurate representations only.
• The Tide Graph displayed by this watch is not intended for navigational purposes.
Always use proper instruments and resources to obtain data for navigation
purposes.
• This watch is not an instrument for calculating low tide and high tide times. The
Tide Graph of this watch is intended to provide a reasonable approximation of
tidal movements only.
• CASIO COMPUTER CO., LTD. assumes no responsibility for any loss, or any
claims by third parties that may arise through the use of this watch.
Bright light
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.

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), 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 will normally 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.
To specify your Home City
1. In the Timekeeping Mode, hold down A for about five

seconds until the watch beeps twice. This indicates the
second hand
watch is in the setting mode.
• Entering the setting mode will cause the stopwatch
second hand to move to the city code of the currently
selected Home City.
2. Use D to change the Home City setting.
• Each press of D causes the stopwatch second hand
to advance clockwise to the next city code.
30
• All hands (except for the second hand) and the date
display will change automatically to the applicable
settings for the currently selected city code. All button
operations are disabled while the hands and date
display are changing.
• Time calibration signal reception is supported when
any one of the city codes shown in the table below is
selected as your Home City.

• 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.
3. After the Home City setting is the way you want, press A to return to the
Timekeeping Mode.
• 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.

Operation Guide 4749
• 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 “Adjusting the Home Positions” to check the home positions of the
hands, and make adjustments as required.
• You can also change the Home City setting by swapping the current Home City and
the currently selected World Time City. For details, see “Swapping your Home City
and World Time City”.

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 signal transmitted by the Fukushima and Fukuoka/Saga,
Japan transmitters include summer time data, summer time currently is not
implemented in Japan (as of 2006).
• The default DST setting is Auto DST (AUTO/AT) whenever you select LON, PAR,
ATH, ANC, LAX, DEN, CHI, NYC, or TYO 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. For more information, see “To set the time and date
manually”.
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”.
• 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.
Make sure there are no metal objects nearby.

• 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.
Mainflingen (Germany) or Anthorn (England) transmitters: 500 kilometers (310
miles)
Fort Collins (United States) transmitter: 600 miles (1,000 kilometers)
Fukushima or Fukuoka/Saga (Japan) transmitters: 500 kilometers (310 miles)
• Even when the watch is within the reception range of the transmitter, signal
reception will be impossible if the signal is blocked by mountains or other geological
formations between the watch and signal source.
• Signal reception is affected by weather, atmospheric conditions, and seasonal
changes.
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.

• 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.
• 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.

Note
• Auto receive is supported in all modes except while a stopwatch elapsed time
operation is in progress.
• Auto receipt 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 14 minutes everyday when the
time in the Timekeeping Mode reaches each of the calibration times. Do not perform
any button operation within 14 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.
• Signal receive is cancelled if an alarm operation starts while it is being performed.
To perform manual receive
1. Place the watch on a stable surface so its 12 o’clock
side is facing towards a window.
2. In the Timekeeping Mode, hold down A for about two
seconds until the watch beeps.
3. The stopwatch second hand will move to READY (R) to
30
indicate that the watch is setting up for time calibration
reception.
• The stopwatch second hand will move to WORK (W)
and stay there while actual reception is in progress.

Y(YES)
• The second hand will stop at “0”.*
* Some models show “60” instead of “0”.
• Time calibration signal reception takes from two to
seven minutes, but in some cases it can take up to 14
30
minutes. Take care that you do not perform any button
operations or move the watch during this time.
N(NO)
• After signal reception is successful, the watch adjusts its hour, minute, 24-hour
hand, and second hand settings, and then returns to the Timekeeping Mode. Next,
the stopwatch second hand moves to Y (YES) momentarily to indicate that signal
reception was successful. After about five seconds, the stopwatch second hand
moves to 12 o’clock.
Note
• To interrupt a receive operation and return to the Timekeeping Mode, press any
button.
• If signal reception fails for some reason, the watch returns to normal timekeeping
without making any adjustments. Next, the stopwatch second hand moves to N (NO)
momentarily to indicate that signal reception failed. After about five seconds, the
stopwatch second hand moves to 12 o’clock.
• If the stopwatch second hand is pointing to Y (YES) or N (NO), you can return to the
Timekeeping Mode by pressing any button.

Power Supply
This watch is equipped with a solar cell and a special rechargeable battery (secondary
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.

Level 2
Jumps 2 seconds
• The second hand jumping every two seconds (Level 2) indicates that battery power
is quite low. Expose the watch to light as soon as possible to charge the battery.
• When battery power is at Level 2, time calibration signal reception is disabled.
• Alarm operation can cause hand movement to stop due to the sudden temporary
drop in battery power. This does not indicate malfunction, and normal operation will
resume when the watch is exposed to light. Though hand movement stops,
timekeeping continues internally, and the hands will be adjusted to the correct
setting when normal operation returns.
• At Level 3, all functions are disabled and settings return to their initial factory
defaults. The watch will continue to keep time internally for about one month after the
battery drops to Level 3. If you recharge the battery sufficiently during this period,
the analog hands will move automatically to the correct setting and normal
timekeeping will resume.
• Internal timekeeping will stop and the Home City setting will change to Tokyo (TYO)
automatically if you leave the watch in the dark for about one month after the battery
level drops to Level 3. 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, you will need to change the Home City code setting to match
your location whenever the battery drops to Level 3.

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. Make sure that the watch is exposed to bright light whenever
possible.
• This watch uses a special 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 special rechargeable battery to charge fully, contact your dealer
or CASIO distributor about having it replaced.
• Never try to remove or replace the watch’s special 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 3 and when you have the battery replaced.
• Keep the watch in an area normally exposed to bright light when storing it for long
periods. This helps to keep the rechargeable battery from going dead.

Approximate Exposure Time
▲
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. Even if the face of the watch
is blocked from light only partially,
charging will be reduced significantly.

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 Return Features
• 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 do not perform any operation for about two or three minutes while a setting
mode is selected, the watch will exit the setting mode automatically.
Scrolling
• The D and B button are used to change the hand setting in various setting modes.
In most cases, holding down these buttons will start high-speed movement of the
applicable hand(s) and day.
• High-speed movement of the hands and day will continue until you press any button,
or until the moving hand(s) and day finish one complete cycle.
– One complete cycle for the hands is one revolution (360 degrees) or 24 hours.
– One complete cycle for the day is 31 days.
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, 2001 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 time within ±20 seconds a month at normal temperature.
Certain charging conditions can cause the watch to become very hot. Avoid leaving
the watch in the areas described below whenever charging its rechargeable battery.
Tidal Movements
Tides are the periodic rise and fall of the water of oceans, seas, bays, and other
bodies of water caused mainly by the gravitational interactions between the Earth,
Moon and Sun. Tides rise and fall about every six hours. The Tide Graph of this watch
indicates tidal movement based on the Moon’s transit over a meridian and the lunitidal
interval. The Tide Graph calculates and graphically represents current tide conditions
in your Home City or a port city in the vicinity of the Home City based on longitudes,
lunar day length, and lunitidal interval preset in watch memory, and on high tide times
specified by you.
Warning!
Leaving the watch in bright light to charge its rechargeable battery can cause it
to become quite hot. Take care when handling the watch to avoid burn injury.
The watch can become particularly hot when exposed to the following
conditions for long periods.
• On the dashboard of a car parked in direct sunlight
• Too close to an incandescent lamp
• Under direct sunlight
Lunitidal Interval
Theoretically, high tide is at the Moon’s transit over the meridian and low tide is about
six hours later. Actual high tide occurs somewhat later, due to factors such as
viscosity, friction, and underwater topography. Both the time differential between the
Moon’s transit over the meridian until high tide and the time differential between the
Moon’s transit over the meridian until low tide are known as the “lunitidal interval”. For
information about the lunitidal intervals for each city code, see “Lunitidal Intervals for
Each City”.

• Since these are the specs, we can include all the technical details.
• Watch is not exposed to light
• Internal timekeeping
• Analog hands operational 18 hours per day, sleep state 6 hours per day
• 10 seconds of alarm operation per day
• 1 time calibration reception per day
• Stable operation is promoted by frequent charging.
• The year can be set in the range of 2001 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 or when battery power drops to
Level 3.
• The date will change automatically when the current time reaches midnight. The
date change at the end of the month may take more time than normal.
• The current time for all city codes in the Timekeeping Mode is calculated in
accordance with the Greenwich Mean Time (GMT) differential of each city, based on
your Home City time setting.
• GMT differential is calculated by this watch based on Universal Time Coordinated
(UTC*) data.
* UTC is the world-wide scientific 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 reference point for UTC is Greenwich,
England.
