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.
Applications
The built-in sensors of this watch measure direction, barometric pressure,
temperature and underwater depth. Measured values are then shown on the
display. Such features make this watch useful when hiking, mountain
climbing, skin diving, or snorkeling, or when engaging in other such outdoor
activities.
Keep the watch exposed to 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. Charging is
reduced significantly if the face is only partially
covered.

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 signal transmitted in
Germany (Mainflingen), England (Rugby), and the United States (Fort
Collins) and the time calibration signals transmitted in Japan.
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” below.
• 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.
• 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.

• 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 also can
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 “Transmitters”.
• See the maps under “Reception Ranges” 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” for more information.
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.

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 each of the calibration
times. Do not perform 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.
To check the latest signal reception results

Barometric Pressure Graph
Barometric pressure indicates changes in the atmosphere. By monitoring
these changes you can predict the weather with reasonable accuracy.
In every mode except for the Depth Gauge Mode, your watch takes barometric
pressure readings every two hours (at the top of each even-numbered hour).
Measurement results are used to produce barometric pressure graph and
barometric pressure differential pointer readings.
The barometric pressure graph shows readings of previous measurements for
up to 30 hours. The horizontal axis of the graph represents time, with each
dot standing for two hours. The rightmost dot (flashing) represents the most
recent reading. The vertical axis of the graph represents barometric pressure,
with each dot standing for the relative difference between its reading and that
of the dots next to it. Each dot represents 1hPa.
The following shows how to interpret the data that appears on the barometric
pressure graph.
A rising graph generally means improving weather.
A falling graph generally means deteriorating weather.
• The margin of error for the angle value is ±11 degrees. If the indicated
direction is northwest (NW) and 315 degrees, for example, the actual
direction can be anywhere from 304 to 326 degrees.
• Any ongoing direction measurement operation is paused temporarily while
the watch is performing an alert operation (daily alarm, Hourly Time Signal,
countdown timer alarm) or while the watch illuminates the display (by
pressing L). The measurement operation resumes for its remaining
duration after the operation that caused it to pause is finished.
• The following table shows the meanings of each of the direction
abbreviations that appear on the display.
Direction Meaning
• The displayed temperature value changes to ---. - °C (or °F) if a
measured temperature falls outside the range of –10.0°C to 60.0°C (14.0°F
to 140.0°F). The temperature value will be displayed again as soon as the
measured temperature is within the allowable range.
• In some areas, barometric pressure is expressed in millibars (mb) instead
of hecto-pascals (hPa). It really makes no difference, because 1hPa = 1mb.
• You can select either hectopascals (hPa) or inchesHg (inHg) as the display
unit for the measured barometric pressure, and Celsius (°C) or Fahrenheit
(°F) as the display unit for the measured temperature value. See “To specify
barometric pressure and temperature units”.

Barometer/Thermometer
This watch uses a pressure sensor to measure air pressure (barometric
pressure) and a temperature sensor to measure temperature.
• You can calibrate the temperature sensor and the pressure sensor if you
suspect that readings are incorrect.
Note that if there are sudden changes in weather or
temperature, the graph line of past measurements may run
off the top or bottom of the display. The entire graph will
become visible once barometric conditions stabilize.

Barometric Pressure Differential Pointer
This pointer indicates the relative difference between the most recent
barometric pressure reading indicated on the barometric pressure graph, and

• The barometric pressure differential pointer is not displayed when the
displayed current barometric value is outside of the allowable measurement
range (600 to 1,100 hPa).
• Barometric pressure is calculated and displayed using hPa as the standard.
The barometric pressure differential also can be read in inHg units as
shown in the illustration.

About Barometric and Temperature Measurements
• Barometric pressure and temperature measurement operations are
performed as soon as you enter the Barometer/Thermometer Mode. After
that, barometric pressure and temperature measurements are taken every
five seconds.
• You also can perform a barometric pressure and temperature measurement
at any time by pressing B in the Barometer/Thermometer Mode.
Depth Gauge
The pressure sensor of the watch also can be used to perform underwater
depth measurement while skin diving or snorkeling. Depth readings are taken
every three seconds, and displayed as a value up to 30 meters (98 feet). You
can store the data of your last dive in log memory, including total time
submerged, maximum depth, and water temperature at the maximum depth
attained during your dive. You can view the log data of your last dive before
beginning a new dive, and even take direction readings while in the Depth
Gauge Mode.
Important!
• This watch is intended for use up to skin diving and snorkeling. Never use
this watch while scuba diving.
• This watch is designed to start depth measurement and record data in
memory after a depth of 1 meter (4 feet) is reached. Because of this, the
explanations in this manual uses the term “submerged” to refer to any
depth deeper than 1 meter, and the “on the surface” to refer to any depth
shallower than 1 meter.
• Leaving the watch in the Depth Gauge Mode while not in the water consumes
battery power. Exit the Depth Gauge Mode whenever you are not using it.
What is “a dive”?
A dive starts when you pass a depth of one meter (about four feet) while the
watch is in the Depth Gauge Mode. The dive ends when you are on the
surface and exit the Depth Gauge Mode. A dive does not end if you surface
but do not exit the Depth Gauge Mode.
Enter the Depth Gauge Mode.

• Remember that the term “dive” as used in this manual refers to skin diving
or snorkeling only.
• The watch will start depth measurement automatically when the sensor
detects that your depth exceeds one meter (about four feet).
• Depth measurement stops automatically whenever your depth becomes
less than one meter (four feet).
• Depth measurement restarts whenever you re-submerge past one meter
(four feet). All data that is measured between the start of the dive and the
end of the dive is treated as part of the same dive, no matter how many
times you surface during the dive.

• You can select either meters (m) or feet (ft) as the display unit for depth. For
details, see "To specify the depth unit".
• See “Depth Data Recall Mode” for information about viewing dive data.
Important!
Note the following important precautions whenever using the Depth Gauge
Mode.
Before Skin Diving/Snorkeling
• Before beginning a dive, check to make sure that none of the
following marks are shown on the display.
❑ CHG (indicating a weak battery)
❑ RECOV (indicating a weak battery)
❑ ERR (indicating sensor malfunction)
(or 0) is displayed at your current depth.
• Make sure that
• Make sure that the watch is set to the correct time of day.
• Check the glass, case and band for cracks or chips.
• Make sure that the band is fastened securely around your wrist.
While Skin Diving/Snorkeling
• Check to make sure that timer operation and depth measurement are
being performed properly.
• Take care when skin diving/snorkeling near rocks or coral to avoid
scratching the watch.
After Skin Diving/Snorkeling
• To avoid corrosion, rinse your watch thoroughly with fresh water to
remove salt water, dirt, etc. When possible, soak the watch in fresh
water overnight to make sure that all salt is removed.
• When using a metal band, clean inside the gaps in the band
occasionally using a soft toothbrush and soapy water. Failure to do so
can result in corrosion of the timepiece, soiling of clothing or irritation
to sensitive skin.
Depth Graph
Changes in depth are displayed in a graph in the Depth Gauge Mode. The
contents of the graph are updated every three seconds whenever you enter
the Depth Gauge Mode.
• The horizontal axis of the graph represents 3-second time increments, and
the bar on the far right is the latest measurement result.
• The vertical axis represents depth values, in 5-meter steps.
0 to 5 meters
5.0 to 10 meters
10.0 to 15 meters
15.0 to 20 meters
20.0 to 25 meters
25.0 to 30 meters
More than 30 meters
• The graph always indicates depths in meters (m), even if you have feet (ft)
selected as the depth unit.
• If you press a button while a measurement operation is in progress, the
measurement operation is stopped, and the graph is not updated.
• Manually resetting the reference depth to 0 meters will change the pressure
reference value. Because of this, all of the graph’s data will be cleared.
• If an error occurs while a measurement operation is in progress, the graph
bar for that measurement is left blank.
• Pressing E while at a depth of less than one meter will toggle between the
depth graph and the temperature screen.

Operation Guide 3047
Depth Gauge Mode Precautions
To view log data
• After you enter the Depth Gauge Mode, the watch takes a reference
pressure reading automatically and sets the result a 0 meters (feet). This
means that before starting a dive, you should enter the Depth Gauge Mode
while at the water’s surface, never while the watch is submerged.
• A major change in air temperature or other phenomena while you are using
the Depth Gauge Mode can cause the display to show a value other than 0
meters (feet) when you are at the surface of the water. If this happens, reset
the reference depth to 0 meters (feet). See “To reset the reference depth to
0 meters (feet) manually” for more information.
• Depth values are displayed in units of 0.1 meter (or 1 foot).
(or 0) appears on the display whenever your depth is less than one
•
meter (four feet).
• dEEP is displayed in place of the depth value whenever your depth is
greater than 30 meters (98 feet). If you continue to dive deeper after dEEP
appears, xx.x will appear in place of the depth value. If xx.x remains on
the display after you surface, hold down D for three seconds to exit the
Depth Gauge Mode. If xx.x keeps appearing in place of the depth value, it
could mean that the sensor is malfunctioning. Take the watch to the place
where you purchased it or to some other CASIO retailer to have it checked.
• If the elapsed measurement time exceeds three hours, the watch will switch
to the Timekeeping Mode automatically and store the data for the current
dive into log memory.
• The progress beeper and auto-repeat timer alarm do not sound while the
watch is in the Depth Gauge Mode.
• The watch can take about five minutes to display the correct water
temperature when there is a great difference between air temperature and
water temperature, when there is a sudden change in water temperature,
etc.
1. Enter the Depth Data Recall Mode.
• This will display the maximum depth record screen.
• Pressing E will toggle between the date screen and the temperature
screen.
2. Press A to display data from the newest to the oldest, or C to display
from oldest to newest.
Depth Data Recall Mode
You can use the Depth Data Recall Mode to view log data that was recorded
in the Depth Gauge Mode. There is enough memory to store up to 40 log
entries, plus one maximum depth record. Each log entry includes the
following data.
Total Time Submerged: This value shows the cumulative amount of time
(hours, minutes, seconds) that you spend submerged at a depth of
one meter (four feet) or greater.
Maximum depth: This value shows the maximum depth you attained during
the dive.
Dive Date (Month – Day)
Water temperature at maximum depth: This value shows the water
temperature at the maximum depth attained during the dive.
The following information is stored in the maximum depth record when a new
maximum is attained.
Total Time Submerged
Maximum depth value: Maximum depth value in memory
Dive Date (Month – Day)
Water temperature at maximum depth
• If the depth that is attained is the same as the current maximum depth
value, the older data takes priority and the maximum depth record is not

Countdown Timer
Timekeeping Mode Time
Minutes
Seconds
You can set a countdown timer start time in the
range of one minute to 60 minutes. An alarm
sounds when the countdown reaches zero. An
auto-repeat feature causes the countdown to
restart automatically when the end of a
countdown is reached, and a progress beeper
signals the progress of the countdown. All of this
makes the countdown timer a valuable tool for
timing the start of a yacht race.
• All of the operations in this section are
performed in the Countdown Timer Mode,
which you enter by pressing D.
Configuring the Countdown Timer
The following are the settings you should configure before actually using the
countdown timer.
• Countdown start time and reset time
• Auto-repeat on/off
• Progress beeper on/off
Countdown start time
You can set a countdown start time from one minute to 60 minutes.
Auto-repeat
Whenever zero is reached, the watch beeps (auto-repeat timer alarm) and
auto-repeat restarts the countdown automatically from the countdown start
time you set. Turning off auto-repeat causes the countdown to stop and the
countdown start time to appear on the display when the end of the countdown
is reached. Auto-repeat will repeat up to 10 times.
Progress Beeper
The progress beeper actually includes two beepers: a reset time beeper and
a reset period progress beeper.
• The reset time beeper and reset period progress beeper sound only while
the progress beeper is turned on.
Reset Time Beeper
The reset time beeper is similar to the countdown end beeper. When the
progress beeper is turned on, the watch beeps each second of the final 10
seconds before the countdown reaches the reset time.

Power Supply
This watch is equipped with a solar cell and a 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.
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.
Charging is reduced significantly if the
face is only partially covered.
Solar cell
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 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.
• All data stored in memory is deleted, and the current time and all other
settings return to their initial factory defaults whenever battery power drops
to Level 5 and when you have the battery replaced.
• Turn on the watch’s Power Saving function 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.

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
▲
Charging Precautions
▲
• Even if battery power is at Level 1 or Level 2, the Digital Compass Mode,
Barometer/Thermometer Mode, or Depth Gauge Mode sensor may be
disabled if there is not enough voltage available to power it sufficiently. This
is indicated by RECOV on the display.
If battery power goes low while a measurement operation is in progress,
the value produced by the last successful measurement operation remains
on the display. Attempting a measurement operation while battery power is
too low will cause the display to go blank.
Sensor operation should resume when battery voltage returns to normal levels.
• If RECOV starts to flash on the display when you enter the Depth Gauge Mode
(before starting measurement), the log data date will not be recorded if you
start measurement after RECOV disappears from the display. In this case, exit
and re-enter the Depth Gauge Mode, and then start the measurement again.
• If RECOV starts to flash while a Depth Gauge Mode depth measurement
operation is in progress, the measurement operation will continue. Though
the elapsed measurement time will be recorded in log memory, maximum
depth and water temperature values are not. In this case, xx.x is displayed
in place of the maximum depth and water temperature. After you surface
from your dive, hold down D for about three seconds to exit the Depth
Gauge Mode to clear RECOV.
• If RECOV appears frequently, it probably means that remaining battery
power is low. Leave the watch in bright light to allow it to charge.
Recovery Times
The table below shows the amount exposure that is required to take the
battery from one level to the next.
Approximate Exposure Time
Exposure Level
(Brightness)

Level 3
Level 2 Level 1
▲
• The flashing LOW indicator at Level 3 and the CHG indicator flashing 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 (M) after falling to Level
4, reconfigure the current time, date, and other settings.
• Display indicators reappear as soon as the battery is charged from Level 5
to Level 2.
• Leaving the watch in 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 power indicator
should appear after a few minutes.
• If you use illumination or the alarm a number of
times during a short period, RECOV appears
on the display and the illumination, alarm,
hourly time signal, and sensor operations
become disabled until battery power recovers.
After some time, battery power will recover and
RECOV will disappear, indicating that the
above functions are enabled again.

• With the 12-hour format, the P (PM) indicator 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.
• The 12-hour/24-hour timekeeping format you select in the Timekeeping
Mode is applied in all modes.
• The year can be set in the range of 2000 to 2099. The day of the week is
calculated automatically in accordance with the date you set.
• The watch’s built-in full automatic calendar makes allowances for different
month lengths and leap years automatically. Once you set the date, there
should be no reason to change it except when battery power drops to Level
5.
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
• The watch will return to the Timekeeping Mode automatically if you leave it
in the Depth Data Recall, Alarm, Receive, Digital Compass, or Barometer/
Thermometer Mode for about two or three minutes without performing any
button operation.
• The watch returns to the Timekeeping Mode automatically if a depth
measurement operation (indicated by ongoing elapsed time measurement
in the upper part of the display) in the Depth Gauge Mode continues for
more than three hours. If there is no depth measurement operation being
or 0 in the center part of the display and no
performed (indicated by
ongoing elapsed time measurement in the upper part of the display), the
watch returns to the Timekeeping Mode automatically if you do not perform
any button operation for about one hour in the Depth Gauge Mode.
• If you leave a screen with flashing digits on the display for two or three
minutes without performing any operation, the watch exits the setting
screen automatically.
Button Operation Tone
Mute indicator
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 D to toggle the button
operation tone on ( not displayed) and off (
displayed).
• Since the D button is also the mode change button, holding it down to turn
the button operation on or off also causes the watch’s current mode to
change.
• You cannot turn button operation tones on or off while a depth
measurement operation is in progress (at depths greater than one meter).
• The
indicator is displayed in all modes when the button operation tone is
turned off.
Scrolling
The C and A buttons are used on the setting screen to scroll through data
on the display. In most cases, holding down these buttons during a scroll
operation scrolls through the data at high speed.
Sensor Malfunction Indicator
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), Rugby
(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.
• The time calibration signals transmitted from Fukushima and Fukuoka/Saga
(Japan) do not include summer time data.
• The default DST setting is Auto DST (AT) whenever you select LON,
PAR, BER, ATH, NYC, CHI, DEN, LAX, ANC, HNL, 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.
To change the Daylight Saving Time (summer time) setting
1. In the Timekeeping Mode, hold down E until the city code starts to flash,
which indicates the setting screen.
2. Press D and the DST setting screen appears.
3. Use C to cycle through the DST settings in the sequence shown below.
Auto DST (AT)
DST off (OFF)
DST on (ON)
4. When the setting you want is selected, press E to exit the setting screen.
• The DST indicator appears to indicate that Daylight Saving Time is turned
on.
• If you change your Home City to one that is within the same transmitter
area, the current DST setting will be retained. If you change to a city that is
outside your current transmitter area, DST will be turned off automatically.
Transmitter area city codes
• HKG, SEL, and TYO
• LAX, DEN, CHI, NYC, ANC, and HNL
• LON, PAR, BER, and ATH
• All other city codes
Subjecting the watch to strong impact can cause its sensor to malfunction or
improper contact of internal circuitry. When this happens, the message ERR
will appear on the display and sensor operations will be disabled.

Measurement
• If ERR appears during digital compass or barometric pressure
measurement, it will disappear from the display as soon as measurement is
successful again.
• During depth measurement, elapsed dive time measurement continues
even if ERR is on the display. After you surface from your dive, hold down
D for about three seconds to exit the Depth Gauge Mode. The ERR
message should no longer be on the display when you re-enter the Depth
Gauge Mode.
• If ERR appears during Depth Gauge digital compass measurement, wait
five or six seconds (or press A) to return to the depth measurement
screen. This should clear the ERR message from the display.
• If the ERR message keeps appearing during measurement, it could mean
there is a problem with the applicable sensor.
Whenever you have a sensor malfunction, be sure to take the watch to
your original dealer or nearest authorized CASIO distributor as soon as
possible.

• The watch will not enter the sleep state while the digital time is between
6:00 AM and 9:59 PM. If the watch is already in the sleep state when the
digital time reaches 6:00 AM, however, it will remain in the sleep state.
• The watch will not enter the sleep state while it is in the Digital Compass,
Barometer/Thermometer, Depth Gauge, Receive, Countdown Timer, or
Stopwatch Mode. When the watch is left in any mode besides the
Countdown Timer and Stopwatch Mode, the watch will return to the
Timekeeping Mode automatically after a specific amount of time. Then if left
in the dark for the elapsed time indicated in the table above, the watch will
enter the sleep state.
To recover from the sleep state
Perform any one of the following operations.
• Move the watch to a well-lit area. It can take up to two seconds for the
display to turn on.
• Press any button.
• Angle the watch towards your face for reading.

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 ±15 seconds a month at normal
temperature.
• 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), and auto receive settings.
• The Home City setting reverts to the initial default of BER (Berlin)
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.
Transmitters
The time calibration signal received by this watch depends on the currently
selected Home City code.
• 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 the 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
(Rugby). The following tables show the reception priority for the European
signals.
The watch does this:
1. Checks the Mainflingen signal first.
2. If the Mainflingen signal cannot be
received, checks the Rugby signal.
1. Checks the signal of the transmitter of the first
receive operation (Rugby or Mainflingen).
2. If the checked signal cannot be received,
checks the other signal.
When LON is selected as the Home City code:
In this case:
The first signal search

City code has been changed
The second and
subsequent signal searches
The watch does this:
1. Checks the Rugby signal first.
2. If the Rugby signal cannot be received,
checks the Mainflingen signal.
1. Checks the signal of the transmitter of the first
receive operation (Rugby or Mainflingen).
2. If the checked signal cannot be received,
checks the other signal.
Timekeeping
• 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 or
when battery power drops to Level 5.
• The current time for all city codes in the Timekeeping Mode is calculated in
accordance with the Greenwich Mean Time (GMT) differential of each zone,
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.
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.
• Illumination turns off automatically whenever an alarm sounds.
• 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.
• Frequent use of illumination runs down the battery.
• Illumination is disabled while the watch is taking a depth reading (every
three seconds).
Auto light switch precautions
• The auto light switch is turned off automatically whenever battery power is
at Level 4.
• Wearing the watch on the inside of your wrist, movement of your arm, or
vibration of your arm can cause frequent activation of the auto light switch
and illumination of the display. To avoid running down the battery, turn off
the auto light switch whenever engaging in activities that might cause
frequent illumination of the display.
• Note that wearing the watch under your sleeve while the auto light switch is
turned on can cause frequent illumination of the display and can run down
the battery.
• Illumination may not turn on if the face of the
More than 15 degrees
watch is more than 15 degrees above or below
too high
parallel. Make sure that the back of your hand
is parallel to the ground.
• Illumination turns off in about one second, even
if you keep the watch pointed towards your
face.
• Static electricity or magnetic force can interfere with proper operation of the
auto light switch. If illumination does not turn on, try moving the watch back
to the starting position (parallel with the ground) and then tilt it back toward
you again. If this does not work, drop your arm all the way down so it hangs
at your side, and then bring it back up again.
• Under certain conditions, illumination may not turn on until about one
second after you turn the face of the watch towards you. This does not
necessarily indicate malfunction of the auto light switch.
• You may notice a very faint clicking sound coming from the watch when it is
shaken back and forth. This sound is caused by mechanical operation of
the auto light switch, and does not indicate a problem with the watch.

Operation Guide 3047
Storage
• The precision of the bearing sensor may deteriorate if the watch becomes
magnetized. Because of this, you should be sure to store the watch away
from magnets or any other sources of strong magnetism, including:
permanent magnets (magnetic necklaces, etc.) and household appliances
(TVs, personal computers, washing machines, freezers, etc.)
• Whenever you suspect that the watch may have become magnetized,
perform one of the calibration procedures under “Calibrating the Bearing
Sensor”.
Calibrating the Bearing Sensor
To perform northerly calibration
1. While in the Digital Compass Mode, hold
down E until x1x appears on the display,
which indicates the setting screen.
2. Press D to start the northerly calibration
procedure.
• At this time, -N- (north) appears on the
display.
ll
lll l lll
Location
• Taking a direction reading when you are near a source of strong magnetism
can cause large errors in readings. Because of this, you should avoid taking
direction readings while in the vicinity of the following types of objects:
permanent magnets (magnetic necklaces, etc.), concentrations of metal
(metal doors, lockers, etc.), high tension wires, aerial wires, household
appliances (TVs, personal computers, washing machines, freezers, etc.)
• Accurate direction readings are impossible while in a train, boat, air plane,
etc.
• Accurate readings are also impossible indoors, especially inside ferroconcrete structures. This is because the metal framework of such structures
picks up magnetism from appliances, etc.
5. Press A again to calibrate the second direction.
• xxx is shown on the display while calibration is being performed. When
calibration is complete, OK appears and then the Digital Compass Mode
screen (showing the angle value) appears.
• If xxx appears and then changes to ERR (error) on the calibration
screen, it means that there is something wrong with the sensor. The ERR
message will disappear after about one second. Try performing the
calibration operation again. If ERR keeps appearing, contact your original
dealer or nearest authorized CASIO distributor to have the watch checked.
lll l lll
This watch features a built-in magnetic bearing sensor that detects terrestrial
magnetism. This means that north indicated by this watch is magnetic north,
which is somewhat different from true polar north. The magnetic north pole is
located in northern Canada, while the magnetic south pole is in southern
Australia. Note that the difference between magnetic north and true north as
measured with all magnetic compasses tends to be greater as one gets
closer to either of the magnetic poles. You should also remember that some
maps indicate true north (instead of magnetic north), and so you should make
allowances when using such maps with this watch.
ll
Digital Compass Precautions
3. Place the watch on a level surface, and position it so that its 12 o’clock
position points north (as measured with another compass).
4. Press A to start the calibration operation.
• --- is shown on the display while calibration is being performed. When
calibration is complete, OK appears and then the Digital Compass Mode
screen (with 0° indicated as the angle value) appears.
• If --- appears and then changes to ERR (error) on the calibration
screen, it means that there is something wrong with the sensor. About one
second after the ERR message appears, -N- will reappear. Try
performing the calibration operation again. If ERR keeps appearing,
contact your original dealer or nearest authorized CASIO distributor to have
the watch checked.
Barometer and Thermometer Precautions
Whenever you suspect that direction readings produced by the watch are
wrong, you should calibrate it. You can use either one of two calibration
procedures: bidirectional calibration or northerly calibration.
Use bidirectional calibration when you want to take readings within an area
exposed to magnetic force. This type of calibration should be used if the
watch becomes magnetized for any reason.
With northerly calibration, you “teach” the watch which way is north (which
you have to determine with another compass or some other means). You
could use this calibration procedure, for example, to set the watch to indicate
true north instead of magnetic north.
• The pressure sensor built into this watch measures changes in air
pressure, which you can then apply to your own weather predictions. It is
not intended for use as a precision instrument in official weather prediction
or reporting applications.
• Sudden temperature changes can affect pressure sensor readings.
• Temperature measurements are affected by your body temperature (while
you are wearing the watch), direct sunlight, and moisture. To achieve a
more accurate temperature measurement, remove the watch from your
wrist, place it in a well ventilated location out of direct sunlight, and wipe all
moisture from the case. It takes approximately 20 to 30 minutes for the
case of the watch to reach the actual surrounding temperature.
Important!
• If you want to perform both bidirectional and northerly calibration, be sure
to perform bidirectional calibration first, and then perform northerly
calibration. This is necessary because bidirectional calibration cancels any
previously set northerly calibration setting.
• The more correctly you perform bidirectional calibration, the better the
accuracy of the bearing sensor readouts. You should perform bidirectional
calibration whenever you change environments where you use the bearing
sensor, and whenever you feel that the bearing sensor is producing
incorrect readings.

press A to calibrate the first direction.
• xxx is shown on the display while calibration is being performed. OK
appears, x2x appears in the center part of the display, and the
magnetic north pointer flashes at the 6 o’clock position when calibration
of the first direction is complete. This means that the watch is ready for
calibration of the second direction.
4. Rotate the watch 180 degrees.

To perform bidirectional calibration
Important!
Incorrectly calibrating the temperature sensor can result in incorrect readings.
Carefully read the following before doing anything.
• Compare the readings produced by the watch with those of another reliable
and accurate thermometer.
• If adjustment is required, remove the watch from your wrist and wait for 20
or 30 minutes to give the temperature of the watch time to stabilize.
ll
Precautions about bidirectional calibration
• You can use any two opposing directions for bidirectional calibration. You
must, however, make sure that they are 180 degrees opposite each other.
Remember that if you perform the procedure incorrectly, you will get wrong
bearing sensor readings.
• Make sure that you do not move the watch while calibration of either
direction is in progress.
• You should perform bidirectional calibration in an environment that is the
same as that where you plan to be taking direction readings. If you plan to
take direction readings in an open field, for example, calibrate in an open
field.
The temperature sensor of this watch is calibrated at the factory before
shipment, and further adjustment normally is not required. If you notice
serious errors in the temperature readings produced by the watch, you can
calibrate the sensor to correct the errors.
1. Enter the Barometer/Thermometer Mode.
2. Hold down E until SET appears in the upper
display area.
3. Release E. After about three or four seconds,
either OFF or a temperature calibration value
(if one is set) will appear in the lower part of
the display. This is the setting screen.
4. Wait four or five seconds until either OFF or a barometric pressure
calibration value (if there is one set) appears in the center part of the display.
5. After waiting four or five seconds, press C (+) or A (–) to change the
displayed temperature by 0.1°C (or 0.2°F).
• Pressing C and A at the same time returns to the factory calibration
(OFF).
6. Press E to exit the setting screen.
Calibrating the Barometric Pressure Sensor
The pressure sensor of this watch is calibrated at the factory before shipment
and further adjustment normally is not required. If you notice serious errors in
the barometric pressure readings produced by the watch, you can calibrate
the sensor to correct the errors.
Important!
Incorrectly calibrating the barometric pressure sensor can result in incorrect
readings. Before performing the calibration procedure, compare the readings
produced by the watch with those of another reliable and accurate barometer.
