Notes
Important!
• The backlight of the watch employs an electroluminescent (EL) light,
which loses illuminating power after very long use.
Avoid wearing the watch on the inside of your wrist. Doing so causes the
Auto Backlight to operate when it is not needed, which shortens battery life.
• Frequent use of the backlight shortens the battery life.
• The illumination provided by the backlight may be hard to see when
viewed under direct sunlight.
• The watch will emit an audible sound whenever the display is illuminated.
This is caused by a transistor that vibrates when the EL panel lights up. It
does not indicate malfunction of the watch.
Moving the watch to a position that is parallel to the ground and then tilting
it towards you more than 40 degrees causes the backlight to illuminate.
• The backlight automatically turns off whenever an alarm sounds.

followed by the value changing to “– – –”.
Digital Compass Precautions
This watch features a built-in magnetic bearing sensor that detects
terrestrial magnetism. This means that the northern direction 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.
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 readings from the Digital Compass.
• Do not move the watch during the one or two seconds (from the point you
press B up to the point that “OK” appears in the upper display) that the
calibration of each direction is in progress. If you do, the message “ERR”
appears in the upper display. When this happens, restart the bidirectional
calibration procedure from the beginning.
• The appearance of “ERR” during bidirectional calibration can also be
caused by local interference. If you suspect that this is the case, move to
another location and try the procedure again.
• You should perform bidirectional calibration in an environment that is the
same as that where you plan to be using the Digital Compass. If you plan
to use it in an open field, for example, calibrate in an open field.
Location
• Using the Digital Compass when you are near a
source of strong magnetism can cause large errors in
readings. Because of this, you should avoid using the
Digital Compass 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.)
To perform northerly calibration

(Normal Display), hold down A until the
upper display changes to show “–1–”.
2. Press C to start the northerly calibration
procedure.
A
• Accurate direction measurements are impossible while in a train, boat, air
plane, etc.
• Accurate measurements are also impossible indoors, especially inside
ferroconcrete structures. This is because the metal framework of such
structures picks up magnetism from appliances, etc.
• At this time, the indicator “N” appears in
the upper display.

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 B to start the calibration
operation.
Storage
D
C
• The precision of the compass 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 Digital
Compass”.
E
• When the calibration procedure is complete, the message “OK” appears
in the upper display. After a short while, the watch automatically returns
to the Digital Compass Mode.
Calibrating the Digital Compass
Whenever you suspect that the readings produced by the Digital Compass
are wrong, you should calibrate it. You can use either one of two calibration
procedures: bidirectional calibration or northerly calibration.
You should use bidirectional calibration when you want to calibrate the Digital
Compass to operate within an area exposed to magnetic force. This type of
calibration should be used if the watch become 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.
ALTIMETER FUNCTIONS
A built-in altimeter uses a pressure sensor to detect the current air
pressure which is then used to estimate the current altitude in accordance
with ISA (International Standard Atmosphere) values for altitude and air
pressure. If you preset a reference altitude, the watch will also calculate the
current relative altitude based on your preset value. Altimeter functions
also include data storage memory and an altitude alarm.
Important!
• This watch estimates altitude based on air pressure. This means that
altitude readings for the same location may vary if air pressure changes.
• Sudden changes in the weather make it impossible to produce accurate
altitude readings.
• This watch employs a semiconductor pressure sensor, which is affected
by temperature changes. When taking altitude measurements, be sure to
do so while ensuring that the watch is not exposed to temperature
changes.
• Do not use this watch while participating in sports where there are
sudden altitude changes. Also, do not use this watch for applications that
demand professional or industrial level precision. This watch should not
be used while engaging in the following activities: sky diving, hang
gliding, paragliding, gyrocopter riding, glider riding, etc.
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.
• If you do not perform any button operation for two or three minutes while
either calibration procedure is in progress (while the magnetic north
indicator is flashing at the 12 or 6 o’clock position), the watch
automatically returns to the Digital Compass Mode.
• The more correctly you perform bidirectional calibration, the better the
accuracy of your Digital Compass readouts. You should perform
bidirectional calibration whenever you change environments where you
use the Digital Compass, and whenever you feel that the Digital Compass
is producing incorrect readings.

2. To stop measurements at any point, hold down D again until the watch
emits a short beep.
• A final measurement is taken when you switch memory measurement off,
and that data is also stored into memory. Such data is indicated by “FIN”
during the recall operation.
About altitude measurements
There are two types of altitude measurements: those for displayed data
(Altimeter Mode measurements) and those for memory data (see “Memory
measurements”).
Setting a Reference Altitude
After you set a reference altitude, the watch automatically calculates the
difference between the current altitude and your preset value. The altitude
measurements produced by this watch are subject to error caused by
changes in atmospheric pressure. Because of this, we recommend that you
set the reference altitude during your climb whenever one is available.
Altimeter mode measurement
This type of measurement is performed only when the watch is in the
Altimeter Mode. As soon as you enter the Altimeter Mode, measurements
are taken every five seconds for the first three minutes. After that,
measurements are taken every two minutes. The display unit for Altimeter
Mode measurements is 5 m, and the measurement range is 0 to 4000 m.
• The measured altitude may be a negative value in cases where there is a
reference altitude value set or because of certain atmospheric conditions.

About the graphic display
You cannot delete data while a memory measurement is in progress
(“AUTO” flashing on the display).
In the Altimeter Mode, the graphic display normally indicates the counting of
the current time’s seconds. When a memory measurement operation is being
performed while the altitude alarm is on, however, the watch automatically
divides the graphic display into 10 equal parts. Each part represents 1/10 of
the difference between the first altitude measured by the memory
measurement operation and the value you set as the altitude alarm. The
graphic representation gives you some idea of how much farther you must
go to reach the altitude indicated by the altitude alarm setting.

Calibrating the barometric pressure measurement
Incorrectly calibrating the temperature measurement of this watch can result
in incorrect readings. Carefully read the following before doing anything.
• Compare the readings produced by the watch with those of another
reliable, 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.
The sensor of this watch is calibrated at the factory before shipment and
further adjustment is normally not required. If noticeable error is found in
the barometric pressure readings produced by the watch, you can adjust it
to correct the error.

WARNING INDICATORS
THERMOMETER FUNCTIONS
Warning indicators appear whenever any of the conditions described below
occur. Appearance of a warning indicator causes any measurement
operation that is currently underway to stop. Warning indicators appear in
the upper display, and this causes “– – –” to replace any directional,
altitude, barometer, or temperature values on the display.
A built-in temperature sensor measures temperature and shows the
measured value on the display. The thermometer can be calibrated.
Important!
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 off
all moisture from the case. It takes approximately 20 to 30 minutes for the
case of the watch to reach the actual surrounding temperature.
Abnormal Magnetic Field Indicator
This indicator appears whenever the Digital
Compass has a problem obtaining a correct
reading. This condition could indicate that
the watch is within a very high magnetic
field, and so you should try moving to
another location. Also, see “Digital
Compass Precautions” for further information on conditions that cause errors.
About temperature measurements
Temperature measurements are taken automatically every five minutes,
regardless of what mode the watch is in. Measured temperature values can
be viewed in the Timekeeping or Altimeter Modes. Temperature
measurements are taken every five seconds for the first three minutes after
you display the Timekeeping Mode’s barometric pressure/temperature
display, or after you enter the Altimeter Mode. After that, temperature
measurements are taken every five minutes.
Low Battery Indicator
This message indicates that battery power
is too low to preform the measurement. It
appears whenever battery power drops
below a certain level, or when you try to
use this watch under very cold conditions

Note that calibrating the Digital Compass may cause the “ERR” message to
appear. In this case, the message does not indicate sensor malfunction,
and should be corrected if you re-calibrate the Digital Compass.

[ Barometric Pressure/Temperature Display ]
• The display shows “– –. – °C” if a measured value falls outside the range
of –10.0°C to 60.0°C. The normal display will return as soon as the
temperature returns within the allowable range.
Important!
• If the sensor is malfunctioning when it comes time for an barometric
pressure measurement to be taken, the barometric pressure value
appears as “– – – –” on the display and the corresponding point on the
barometric pressure graph is left blank.
• There may be cases where the “ERR” or “BAT” message is cleared once
you change modes. In this case, you can continue using the watch
normally unless the error warning message reappears.
• For details on viewing the temperature in the Altimeter Mode, see
“Understanding the altimeter display”.
Calibrating the temperature measurement
The temperature sensor of this watch is calibrated at the factory before
shipment and further adjustment is normally not required. If noticeable error
is found in the temperature readings produced by the watch, you can adjust
it to correct the error.
Whenever there is a sensor malfunction, be sure to take the watch to an
authorized CASIO distributor or Service Center as soon as possible.

ALARM FUNCTIONS
QUESTIONS & ANSWERS
Mode indicator
Five independent daily alarms can be set.
Question: What causes incorrect direction readings?
Answer:
• Incorrect bidirectional calibration. Perform bidirectional calibration.
Remember that bidirectional calibration is required whenever batteries
are replaced.
• Nearby source of strong magnetism, such as a household appliance, a
large steel bridge, a steel beam, overhead wires, etc., or an attempt to
perform Digital Compass operation on a train, boat, etc. Move away
from large metal objects and try again. Note that digital compass
operation cannot be performed inside a train, boat, etc.
Each alarm lets you set the hour and
minutes. When the Daily Alarm is on, the
alarm sounds for 20 seconds at the preset
time each day. Press any button to stop the
alarm after it starts to sound.
When the Hourly Time Signal is on, the
watch beeps every hour on the hour.
• The segments in the graphic display
create a rotational movement effect while
an alarm is sounding.

• Direction being measured is somewhere between two measurable
directions (N and NNW, for example). The Digital Compass is designed
to indicate any one of 16 different directions. If you move the 12 o’clock
position slightly to the left or right (to move it off of the point between
the two measurable directions), the Digital Compass should consistently
produce the same reading.
• Magnetism generated by nearby high-tension wires are interfering with
reception of terrestrial magnetism. Move away from the high-tension
wires and try again.

Hourly Time Signal
3. After you select an alarm, hold down A until the hour digits flash on the
display. The hour digits flash because they are selected.
• At this time, the alarm is automatically switched on.
Question: What does it mean when “– – –” appears in place
of a direction?
Answer: This is the abnormal magnetic field indicator. It means that
strong magnetism is being generated nearby. Move away from the
source of strong magnetism and try again.
4. Press C to change the selection in the following sequence.
Hour
Minutes
Question: Why am I having problems performing Digital
Compass operations indoors?
5. Press D to increase the selected digits and B to decrease them.
Holding down either button changes the selection at high speed.
• The format (12-hour or 24-hour) of the alarm time matches the format you
selected for normal timekeeping.
• When setting the alarm time using the 12-hour format, take care to set
the time correctly as morning (no indicator) or afternoon (P).
Answer: TV, personal computer, speakers, or some other object is
interfering with terrestrial magnetism. Move away from the object
causing the interference or perform the Digital Compass operation
outdoors. Indoor Digital Compass operations are particularly difficult
inside ferroconcrete structures. Remember that you cannot perform
Digital Compass operations inside of trains, airplanes, etc.
6. After you set the alarm, press A to return to the Alarm Mode.
Question: How does the altimeter work?
To switch an alarm or the Hourly Time Signal on and off
Answer: Generally, atmospheric pressure and temperature decrease
as altitude increases. This watch is equipped with a pressure sensor
and bases its altitude measurements on International Standard
Atmosphere (ISA) values stipulated by the International Civil Aviation
Organization (ICAO), which define relationships between altitude,
atmospheric pressure, and temperature.
1. In the Alarm Mode, press D to select an alarm or the Hourly Time Signal.
2. When the alarm or Hourly Time Signal you want to is selected, press B
to switch it on and off.

The Stopwatch Functions let you measure
elapsed time, split times, and two finishes.
The range of the stopwatch is 23 hours, 59
minutes, 59.99 seconds.
There are two standard methods of expressing altitude: Absolute altitude
and Relative altitude. Absolute altitude expresses an absolute height above
sea level. Relative altitude expresses the difference between the height of
two different places.

Question: What do the numbers on the watch mean?
Answer: The face of this watch is marked with
values that increase in a counterclockwise
direction. These values represent degrees.
N
0
When you take a direction reading, you can
use these values to find out how many
degrees the 12 o’clock position of this watch
(which is the direction indicated in the digital
display) differs from magnetic north.
P
A
S
BEARING
For example, when the Magnetic North
Indicator is pointing at “90” on the watch’s
face, it means that the 12 o’clock position is
90 degrees from magnetic north (which
means that 12 o’clock is pointing due east).

Question: How does the barometer work?
Answer: Barometric pressure indicates changes in the atmosphere, and
by monitoring these changes you can predict the weather with reasonable
accuracy. Rising atmospheric pressure indicates good weather, while
falling pressure indicates deterioration weather conditions.
The atmospheric pressure that you see in the newspaper and on the TV
weather report are measurements corrected to values measured at 0 m
sea level.
Question: What should I do if I lose track of which mode I am
in or lose my way when making settings?
Answer: Hold down the C button for two or three seconds to return to
the Timekeeping Mode. Next, try performing the operation you want
again.
