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.

About This Manual
• Depending on the model of your watch, digital display text appears
either as dark fi gures on a light background, or light fi gures on a dark
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!
• Your watch’s Altimeter Mode calculates relative altitude based on changes in barometric pressure
measurement by its pressure sensor. For more information, see pages E-51 and E-65.
• Immediately before embarking or otherwise taking altitude readings, be sure to specify a reference
altitude. If you don’t the readings produced by the watch probably will not be very accurate. For more
information, see “To specify a reference altitude value” (page E-58).
• 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. For more information, see “To perform bidirectional calibration” (page E-30).

Important!
• Allowing the watch to become very hot can cause its liquid crystal display to black out. 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-13) 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

• Display indicators reappear as soon as the battery is charged from Level 5 to Level 2 (M).
• Leaving the watch exposed to 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 level should be indicated after a few minutes.
• 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.
Power Recovery Mode
• Performing multiple sensor, illumination, or beeper operations during a short period may cause all of
the battery power indicators (H,M, and L) to start fl ashing on the display. This indicates that the watch
is in the power recovery mode. Illumination, alarm, countdown timer alarm, hourly time signal, and
sensor operations will be disabled until battery power recovers.
• Battery power will recover in about 15 minutes. At this time, the battery power indicators (H,M,L) will
stop fl ashing. This indicates that the functions listed above are enabled again.
• If all of the battery power indicators (H,M,L) are fl ashing and the
fl ashing, it means the battery level is very low. Expose the watch to bright light as soon as possible.
• Even if battery power is at Level 1 (H) or Level 2 (M), the Digital Compass Mode, Barometer/
Thermometer Mode, or Altimeter Mode sensor may be disabled if there is not enough voltage available
to power it suffi ciently. This is indicated when all of the battery power indicators (H,M,L) are fl ashing.
• Frequent fl ashing of all of the battery power indicators (H,M,L) probably means that remaining battery
power is low. Leave the watch in bright light to allow it to charge.

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.
• 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-38) 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°.
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.

Bearing Memory lets you temporarily store and display a direction
reading so you can use it as a reference as you take subsequent digital
compass readings. The Bearing Memory screen displays the direction
angle for the stored reading, along with a pointer that indicates the stored
reading.
When you take digital compass readings while the Bearing Memory
screen is displayed, the direction angle of the current digital compass
reading (as read from the 12 o’clock position of the watch) and the stored
Bearing Memory direction reading will both be shown.
To store a direction angle reading in Bearing Memory
1. Press C to start a digital compass reading operation (page E-26).
• This will ta ke an initial read ing and then t ake readings ever y
second for 6 0 seconds.
• If a bearing me mory dire ction angl e value is already d isplayed, it
means that t here is a reading al ready stored in B earing Me mory. If
this happens, press E to clear the B earing Mem ory readin g and
exit the bearing memory screen before performing the above step.
3. Rotate the map without moving the watch so the northerly direction
indicated on the map matches north as indicated by the watch.
• If the watch is con fi gured to indicate m agnetic nor th, align th e
map’s magnetic n orth wit h the watch indicat ion. If the watch h as
been confi gured with a dec lination to co rrect to true n orth, alig n
the map’s true n orth with t he watch indicat ion. For det ails, see
“Calibratin g the Bearin g Sensor ” (page E-28).
• This will position the map in accordance with your current location.
4. Determine your location as you check the geographic contours around
you.
2. During the 60 seconds that digital compass readings are being taken, press E to store the current
reading in Bearing Memory.
• The Beari ng Memor y directio n angle fl ashes f or about on e second as it i s stored in Bea ring
Memor y. After that, th e Bearing M emory sc reen (which sh ows the beari ng memor y direction a ngle
and pointer) wil l appear, and a new 6 0-se cond direct ion reading op eration will s tart.
• You can press C at any time whil e the Bearin g Memor y screen is disp layed, to star t a new
60- second di rection readi ng operatio n. Doing so w ill display the di rection ang le for the direc tion
that the 12 o’clock po sition of the wa tch is pointed. T he directio n angle of the cur rent reading wil l
disappear f rom the displ ay after the 6 0-se cond direct ion reading op eration is co mplete.
• During the fi rst 60 seco nds after yo u display the Be aring Mem ory scree n or during a 6 0-se cond
direction re ading operati on you trigge red by pressing C while the Be aring Mem ory scree n is on
the display, the direc tion stored in m emory i s indicated by a Be aring Mem ory pointe r.

Using the Digital Compass While Mountain Climbing or Hiking
This section provides three practical applications for using the watch’s built-in digital compass.
• 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.
• Finding the bearing to an objective
• Determining the direction angle to an objective on a map and heading in that direction

1. With the watch on your wrist, position it so the face is horizontal.
2. Set the map so its northerly indication is aligned with north as indicated
by the watch, and determine your current location.
• See “To set a map an d fi nd your current l ocation” o n page E-3 4 for
informati on about how to p erform t he above step.
3. Next, set the map so the direction you want to travel on the map is
pointed straight in front of you.
4. While in the Timekeeping Mode or in any of the sensor modes, press
C
to take a compass reading.
• The reading wi ll appear on t he display afte r about one s econd.
5. Still holding the map in front of you, turn your body until north as
indicated by the watch and the northerly direction on the map are
aligned.
• This will po sition the m ap in accorda nce with your c urrent loca tion,
so the beari ng to your object ive is straight ah ead of you.

1. Set the map so its northerly indication is aligned with north as indicated
by the watch, and determine your current location.
• See “To set a map an d fi nd your current l ocation” o n page E-3 4 for
informati on about how to p erform t he above step.
2. As shown in the illustration to the left, change your position so you (and
the 12 o’clock position of the watch) are pointed in the direction of
objective, while keeping the northerly direction indicated on the map
aligned with north as indicated by the watch.
• If you fi nd it dif fi cult to per form the ab ove step while kee ping
everyth ing aligned, fi rs t move into the cor rect positi on (12 o’clock
position o f the watch pointed a t the objecti ve) without worr ying
about the o rientatio n of the map. Nex t, perfo rm step 1 again to s et
the map.
The northerly direction can be expressed either as magnetic north or true
north, which are different from each other. Also, it is important to keep in mind
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.

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.) 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
perform bidirectional calibration” (page E-30).

3. While in the Timekeeping Mode or in any of the sensor modes, press
C
to take a compass reading.
4. While direction angle readings are in progress, press E to record the
currently displayed direction in Bearing Memory.
• The directi on angle value a nd pointer sto red in Bearin g Memor y
will remain o n the display for a bout 60 se conds.
• To re-display th e Bearing M emory di rection angl e value and
Bearing Memory pointer, press C.
• See “Usi ng Bearing M emory ” (page E-3 2) for more infor mation.
5. Now you can advance while monitoring the Bearing Memory pointer to
ensure that it remains in the 12 o’clock position.
• Pressing E while the Be aring Mem ory direct ion angle valu e and
Bearing M emory po inter are on the d isplay will clea r the Beari ng
Memor y data you saved in s tep 3 and save the cu rrent directio n
reading in Bearing Memory.
Note
• When mountain climbing or hiking, conditions or geographic
contours m ay make it impos sible for you to ad vance in a straig ht
line. If this ha ppens, retur n to step 1 and save a new d irection to
the objective.
E-37
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.
