Congratulations upon your selection of this CASIO watch.
Applications
The built-in sensors of this watch measure direction, barometric pressure, temperature and altitude.
Measured values are then shown on the display. Such features make this watch useful when hiking,
mountain climbing, or when engaging in other such outdoor activities.
• The measurement functions built into this watch are not intended for taking measurements that
require professional or industrial precision. Values produced by this watch should be considered
as reasonable representations only.
•
When engaging in mountain climbing or other activities in which losing your way can create a
dangerous or life-threatening situation, always use a second compass to confi rm direction readings.
• Note that CASIO COMPUTER CO., LTD. assumes no responsibility for any damage or loss
suffered by you or any third party arising through the use of this product or its malfunction.

background. All examples in this manual are shown using dark fi gures
on a light background.
• Button operations are indicated using the letters shown in the
illustration.
• Note that the product illustrations in this manual are intended for
reference only, and so the actual product may appear somewhat
different than depicted by an illustration.
Important!
• The watch’s Altimeter Mode calculates and displays relative altitude based on barometric pressure
readings produced by its pressure sensor. This means that readings taken at different times at the
same location may produce different altitude values due to changes in barometric pressure. Also note
that the value displayed by the watch may be different from the actual elevation and/or sea level
elevation indicated for the area where you are located.
• When using the watch’s altimeter while mountain climbing, be sure to perform regular calibration in
accordance with the local altitude (elevation) indications. For more information, see “To specify a
reference altitude value” (page E-57).
• Whenever you use the digital compass of this watch for serious trekking, mountain climbing, or other
activities, be sure always to take along another compass to confi rm readings. If the readings produced
by the digital compass of this watch are different from those of the other compass, perform bidirectional
calibration of the digital compass to ensure more accurate readings.
• Direction readings and digital compass calibration will not be possible if the watch is in the vicinity of a
permanent magnet (magnetic accessory, etc.), metal objects, high-voltage wires, aerial wires, or
electrical household appliances (TV, computer, cellphone, etc.)
Using the Crown
This watch has a lock-type crown.
Important!
• You should keep the crown locked during normal daily use. Leaving the crown unlocked creates the

• Allowing the watch to become very hot can cause its liquid crystal display to go blank (totally black or
totally white, depending on the watch model). The appearance of the LCD should become normal
again when the watch returns to a lower temperature.
• Turn on the watch’s Power Saving function (page E-18) and keep it in an area normally exposed to
bright light when storing it for long periods. This helps to ensure that power does not run down.
• 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 power to run down. Expose the watch to bright light
whenever possible.

Charging the Watch
The face of the watch is a solar panel that generates power from light. The generated power charges a
built-in rechargeable battery, which powers watch operations. The watch charges whenever it is exposed
to light.
Charging Guide
Whenever you are not wearing the
watch, leave it in a location where it
is exposed to light.
• Best charging performance is
achieved by exposing the watch to
the strongest light available.
Warning!
Leaving the watch in bright light for charging 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

Radio Controlled Atomic Timekeeping
This watch receives a time calibration signal and updates its time setting accordingly. However, when
using the watch outside of areas covered by time calibration signals, you will have to adjust the settings
manually as required. See “Confi guring Current Time and Date Settings Manually” (page E-36) for more
information.
This section explains how the watch updates its time settings when the city code selected as the Home
City is in Japan, North America, Europe, or China, and is one that supports time calibration signal
reception.
If your Home City Code setting is this:
LONDON (LON), PARIS (PAR), ATHENS (ATH)Anthorn (England), Mainfl ingen (Germany)
HONG KONG (HKG)Shangqiu City (China)
TOKYO (TYO)Fukushima, Fukuoka/Saga (Japan)
NEW YORK (NYC), CHICAGO (CHI), DENVER (DEN), LOS
ANGELES (LAX), ANCHORAGE (ANC), HONOLULU (HNL)
Important!
• The areas covered by
conditions may cause reception problems.
• Even when the watch is within range of a transmitter, signal reception may be impossible due to the
effects of geographic contours, structures, weather, the time of year, the time of day, radio interference,
etc. The signal becomes weaker at distances of approximately 500 kilometers, which means that the
infl uence of the conditions listed above becomes even greater.
• 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.
Mainfl ingen (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)
Shangqiu (China) transmitter: 500 kilometers (310 miles)
• As of December 2013, China does not use Daylight Saving Time (DST). If China does go to the Daylight
Saving Time system in the future, some functions of this watch may no longer operate correctly.

Auto Receive
• With auto receive, the watch performs the receive operation each day automatically up to six times (up
to fi ve times for the Chinese calibration signal) between the hours of midnight and 5 a.m. (according to
the Timekeeping Mode time). When any receive operation is successful, none of the other receive
operations for that day are performed.
• When a calibration time is reached, the watch will perform the receive operation only if it is in the
Timekeeping Mode. The receive operation is not performed if a calibration time is reached while you
are confi guring settings.

Taking Direction Readings
You can use the Digital Compass Mode to determine the direction of north, and to check your bearing to a
destination.
• For information about what you can do to improve digital compass reading accuracy, see “Calibrating
the Bearing Sensor” (page E-46) and “Digital Compass Precautions” (page E-50).
E-42
To take a direction reading
1. Make sure the watch is in the Timekeeping, Digital Compass, or Altimeter Mode.
2. Place the watch on a fl at surface. If you are wearing the watch, make sure that your wrist is horizontal
(in relation to the horizon).
3. Point the 12 o’clock position of the watch in the direction whose reading you want to take.

• Any ongoing direction reading operation is paused temporarily while the watch is performing an alert
operation (daily alarm, Hourly Time Signal, countdown timer alarm) or while illumination is turned on (by
pressingL). The direction reading operation resumes for its remaining duration after the operation
that caused it to pause is fi nished.
• See “Digital Compass Precautions” (page E-50) for important information about taking direction readings.
Calibrating the Bearing Sensor
You should calibrate the bearing sensor whenever you feel that the direction readings being produced by
the watch are off. You can use any one of two different bearing sensor calibration methods: bidirectional
calibration or magnetic declination correction.
Bidirectional Calibration
•
Bidirectional calibration calibrates the bearing sensor in relation to magnetic north. 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.
Important!
• To ensure correct direction readings by this watch, be sure to perform bidirectional calibration before
using it. The watch may produce incorrect direction readings if you do not perform bidirectional
calibration.
Magnetic Declination Correction
•
With magnetic declination correction, you input a magnetic declination angle (difference between
magnetic north and true north), which allows the watch to indicate true north. You can perform this
procedure when the magnetic declination angle is indicated on the map you are using. Note that you can
input the declination angle in whole degree units only, so you may need to round off the value specifi ed
on the map. If your map indicates the declination angle as 7.4°, you should input 7°. In the case of 7.6°
input 8°, for 7.5° you can input 7° or 8°.

Note
• The watch will ret urn to the Tim ekeeping Mo de about 6 0 seconds af ter the direction reading
operation is complete.
• To restart a readin g operation f rom the begin ning, press C.
• Pressing B will return to th e Timekee ping Mode even i s a reading opera tion is in prog ress.
Important!
• If the second hand does not point exactly at 12 o’clock after you perform step 4 above, perform the
operation under “Hand Home Position Adjustment” (page E-39) to adjust it.
• If the digital display contents start to fl ash after you perform a reading operation, it means that
abnormal magnetism has been detected. Move away from any potential source of strong magnetism
and try taking a reading again. If the problem occurs when you try again, continue to keep away from
the source of strong magnetism, perform bidirectional calibration, and then try taking a reading again.
For more information, refer to “To perform bidirectional calibration” (page E-48) and “Location” (page
E-51).
Digital Compass Readings
• After the fi rst reading is obtained, the watch will continue to take digital compass readings automatically
each second for up to 60 seconds. After that, the reading operation will stop automatically.
• The auto light switch is disabled during the 60 seconds that digital compass readings are being taken.
• The margin of error for the angle value and the direction indicator is ±11 degrees while the watch is
horizontal (in relation to the horizon). If the indicated direction is northwest (NW) and 315 degrees, for
example, the actual direction can be anywhere from 304 to 326 degrees.
• Note that taking a direction reading while the watch is not horizontal (in relation to the horizon) can
result in large direction reading error.
•
You can calibrate the bearing sensor if you suspect the direction reading is incorrect.
E-45
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.
• 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 fi eld, for example,
calibrate in an open fi eld.

Setting a map and fi nding your current location
Having an idea of your current location is important when mountain climbing or hiking. To do this, you
need to “set the map”, which means to align the map so the directions indicated on it are aligned with the
actual directions of your location. Basically what you are doing is aligning north on the map with north as
indicated by the watch.
• Note that map reading skills and experience are required to determine your current location and
destination on a map.

that magnetic north moves over time.
• Magnetic north is the north that is indicated by the needle of a compass.
• True north, which is the location of the North Pole of the Earth’s axis, is the
north that is normally indicated on maps.
• The difference between magnetic north and true north is called the
“declination”. The closer you get to the North Pole, the greater the
declination angle.

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 readings are also impossible indoors, especially inside ferroconcrete structures. This is
because the metal framework of such structures picks up magnetism from appliances, etc.
• Accurate direction readings are impossible while in a train, boat, air plane, etc.
Storage
• The precision of the bearing sensor may deteriorate if the watch becomes magnetized. Because of
this, you should store the watch away from magnets or any other sources of strong magnetism,
including: permanent magnets (magnetic necklaces, etc.), concentrations of metal (metal doors,
lockers, etc.), and household appliances (TVs, personal computers, washing machines, freezers, etc.).
• Whenever you suspect that the watch may have become magnetized, perform the procedure under “To

Using the Altimeter Mode
The watch takes altitude readings and displays results based on air pressure measurements taken by a
built-in pressure sensor. It also saves various types of altitude records and data.
• The displayed altitude reading is a relative altitude that is calculated based on measurement of
changes in barometric pressure by the watch’s pressure sensor. This means that barometric pressure
changes can cause readings taken at different times at the same location to be different. Also note that
the value displayed by the watch may be different from the actual elevation and/or sea level elevation
indicated for the area where you are located. When using the watch’s altimeter while mountain
climbing, it is recommended that you perform regular calibration in accordance with the local altitude
(elevation) indications.
Important!
• See “To specify a reference altitude value” (page E-57) and “Altimeter Precautions” (page E-68) for
information about how to minimize differences between readings produced by the watch and values
provided by local altitude (elevation) indications.

Using Reference Altitude Values
To minimize the chance of reading error, you should update the reference altitude value before setting off
on a trek or any other activity where you plan to take altitude readings. During a trek, keep checking the
readings produced by the watch against altitude information provided by markers and other information,
and update the reference altitude value as required.
• Reading error can be caused by changes in barometric pressure, atmospheric conditions, and
elevation.
• Before performing the procedure below, look up the altitude of your current location on a map, the
Internet, etc.

If you specify a reference altitude, the second hand of the watch will
indicate the difference between the current altitude and the reference
altitude. The displayed altitude differential value is updated each time the
watch obtains a new altitude reading value.
• Depending on the currently selected display range, the allowable
range for the altitude differential value is 100 meters to –100 meters
(100 meters = 328 feet), or 1,000 meters to –1,000 meters (1,000

Auto Save Values
Auto save values are one type of data stored in the memory of your watch.
• These values are checked and updated automatically by the watch as altitude auto measurements are
taken.
• Auto save is performed only while the watch is in the Altimeter Mode.
• Cumulative ascent and cumulative descent values are updated whenever there is a difference of at
least ±15 meters (±49 feet) from one reading to the next.
• Auto save values also include the date and time each value was recorded.
How High and Low Altitude Values are Updated
With each auto save reading, the watch compares the current reading against the

How does the altimeter work?
Generally, air pressure decreases as altitude increases. This watch bases its altitude reading on
International Standard Atmosphere (ISA) values stipulated by the International Civil Aviation Organization
(ICAO). These values defi ne relationships between altitude and air pressure.
• Note that the following conditions will prevent you from obtaining accurate readings:
When air pressure changes because of changes in the weather
Extreme temperature changes
When the watch itself is subjected to strong impact
There are two standard methods of expressing altitude: absolute altitude, which expresses an absolute
height above sea level, and relative altitude, which expresses the difference between the altitudes of two
different places. This watch expresses altitudes as relative altitude.
(300 m) + e (620 m) = 920 m

Altimeter Precautions
• This watch estimates altitude based on air pressure. This means that altitude readings for the same
location may vary if air pressure changes.
• Do not use this watch for altitude reading or perform button operations while sky diving, hang gliding,
or paragliding, while riding a gyrocopter, glider, or any other aircraft, or while engaging in any other
activity where there is the chance of sudden altitude changes.
• Do not use this watch for measuring altitude in applications that demand professional or industrial level
precision.
• Remember that the air inside of a commercial aircraft is pressurized. Because of this, the readings
produced by this watch will not match the altitude readings announced or indicated by the fl ight crew.

will appear on the display, indicating that barometric pressure
reading is in progress. The results will appear on the display after
about one second.
• After a barometric pressure reading operation is started, the watch will
take readings every fi ve seconds for the fi rst three minutes, and then
every two minutes after that.
• To restart a reading operation from the beginning, press A.
• The watch will return to the Timekeeping Mode automatically if you do
not perform any operation for about one hour after entering the
Barometer Mode.
Note
• When you press B above, the second hand may indicate seconds (of
the current time) or the barometric pressure differential (page E-73).
The initial second hand function will be the same as what was selected
the last time you took a barometric pressure reading. To toggle
between the two second hand functions (indicating seconds or
indicating the barometric pressure differential) press D.
Regular calibration of the watch in accordance with values provided by local altitude (elevation) indications
is recommended before taking readings in order to maximize reading accuracy (page E-56).

Precautions Concerning Simultaneous Altitude and Temperature Readings
For the more accurate altitude readings, leaving the watch on your wrist is recommended in order to
maintain the watch at a constant temperature.
• When taking temperature readings, keep the watch at as stable a temperature as possible. Changes in
temperature can affect temperature readings. See product specifi cations (page E-111) for sensor
accuracy information.
• Barometric pressure is displayed in units of 1 hPa (or 0.05 inHg).
•
The displayed barometric pressure value changes to
barometric pressure falls outside the range of 260 hPa to 1,100 hPa (7.65
inHg to 32.45 inHg). The barometric pressure value will reappear as
soon as the measured barometric pressure is within the allowable range.
Display Units
You can select either hectopascals (hPa) or inchesHg (inHg) as the
display unit for the measured barometric pressure. See “To specify
altitude, barometric pressure, and temperature units” (page E-52).
Barometric pressure indicates changes in the atmosphere. By monitoring
these changes you can predict the weather with reasonable accuracy.
This watch takes barometric pressure reading automatically every two
hours. Readings are used to produce barometric pressure graph and
barometric pressure differential pointer readings.

• The horizontal axis of the graph represents time, with each dot standing for
two hours. The rightmost dot 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 1 hPa.
The following shows how to interpret the data that appears on the barometric pressure graph.
Rising barometric pressure indicates that upcoming weather will improve.
Falling barometric pressure indicates that upcoming weather will deteriorate.
Note
• If there are sudden changes in weather or temperature, the graph line of past reading
may run off the top or bottom of the display.
• The following conditions cause the barometric pressure reading to be skipped, with
the corresponding point on the barometric pressure graph being left blank.
– Barometric reading that is out of range (260 hPa to 1,100 hPa or 7.65 inHg to 32.45

Barometric Pressure Change Indications
Your watch analyzes past barometric pressure readings and uses a barometric pressure change indicator
to inform you about changes in pressure. If the watch detects a signifi cant change in barometric pressure,
it will beep and display a fl ashing arrow that indicates the direction of the pressure change. This means
you could start taking barometric pressure readings after reaching a lodge or camp area, and then check
the watch the next morning for changes in pressure, and plan you day’s activities accordingly. Note that
you can enable or disable display of the barometric pressure change indicator as desired.
The barometric pressure change indicator is displayed in the Barometer Mode and while the barometric
pressure graph is displayed in the Timekeeping Mode (page E-33).

Important!
• To ensure proper results, take barometric readings under conditions where the altitude remains
constant.
Example
– In a lodge or campground
– On the ocean
• A change in altitude causes a change in barometric pressure. Because of this, correct readings are
impossible. Do not take readings while ascending or descending a mountain, etc.

Pressure Sensor Calibration
The pressure sensor built into the watch are calibrated at the factory and normally require no further
adjustment. If you notice serious errors in the 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.
E-77
Barometer Precautions
• 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 offi cial weather
prediction or reporting applications.
• Sudden temperature changes can affect pressure sensor readings. Because of this, there may be
some error in the readings produced by the watch.

About the Auto Light Switch
Turning on the auto light switch causes illumination to turn on,
whenever you position your wrist as described below in any mode.
Moving the watch to a position that is parallel to the ground and
then tilting it towards you more than 40 degrees causes
illumination to turn on.
Warning!
Always make sure you are in a safe place whenever you are reading the display of the watch
•
using the auto light switch. Be especially careful when running or engaged in any other activity
that can result in accident or injury. Also take care that sudden illumination by the auto light
switch does not startle or distract others around you.
When you are wearing the watch, make sure that its auto light switch is turned off before riding
•
on a bicycle or operating a motorcycle or any other motor vehicle. Sudden and unintended
operation of the auto light switch can create a distraction, which can result in a traffi c accident
and serious personal injury.

Illumination Precautions
• The LED 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.
• Frequent use of illumination runs down the battery.
Auto light switch precautions
• 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.
C
To turn Power Saving on or off
• Illumination may not turn on if the face of the watch is more than 15 degrees above
or below parallel. Make sure that the back of your hand is parallel to the ground.
• Illumination turns off after the preset illumination duration (page E-98), 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 towards your face
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.
• 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.

If you are using the watch in an area where time calibration signal reception is possible, see “To confi gure
Home City and summer time settings” (page E-34).
If you are using in the watch in an area where time calibration signal reception is not possible, you may
need to change your Home City’s standard time/daylight saving time (DST) setting manually. Use the
procedure under “To change the current time and date settings manually” (page E-36) to change the
standard time/daylight saving time (DST) setting.
Altitude Readings
Altitude readings produce different results at the same location.
■
Readings produced by the watch are different from the elevation and/or sea level altitude
■
indications in my area. (Negative sea level altitude values are produced in a location where the
indicated elevation is a positive value.)
I can’t get correct altitude readings.
■
Relative altitude is calculated based on changes in barometric pressure measurement by its pressure
sensor. This means that barometric pressure changes can cause readings taken at different times at the
same location to be different. Also note that the value displayed by the watch may be different from the
actual elevation and/or sea level elevation indicated for the area where you are located.
When using the watch’s altimeter while mountain climbing, you need to be sure to perform regular
calibration in accordance with the local altitude (elevation) indications.
For more information, see “To specify a reference altitude value” (page E-57).
Following a relative altitude reading, the watch’s second hand points to 9 o’clock.
