switch automatically lights the watch face
whenever you turn your wrist towards your
face.
• The auto light switch on indicator is shown on the display in all modes while
the auto light switch is on.
• In order to protect against running down the battery, the auto light switch is
automatically turned off approximately six hours after you turn it on. Repeat
the above procedure to turn the auto light switch back on if you want.
• Pressing B in any mode (except for the Recall Mode) illuminates the
display for about two seconds, regardless of the auto light switch on/off
setting.

Notes
• The backlight of the watch employs an electroluminescent (EL) light, which
loses illuminating power after very long use.
• 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. It
does not indicate malfunction of the watch.
• The backlight automatically turns off whenever an alarm sounds.
Important!
Avoid wearing the watch on the inside of your wrist. Doing so causes the auto
light switch to operate when it is not needed, which shortens battery life.
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 turns off in about two seconds, 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 the backlight does not illuminate, 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 the backlight may not light until about one second
or less after turn the face of the watch towards you. This does not necessarily
indicate malfunction of the backlight.
Warning!
• Never try to read your watch when mountain climbing or hiking in
areas that are dark or in areas with poor footing. Doing so is dangerous
and can result in serious personal injury.
• Never try to read your watch when running where there is the danger
of accidents, especially in locations where there might be vehicular or
pedestrian traffic. Doing so is dangerous and can result in serious
personal injury.
• Never try to read your watch when riding on a bicycle or when
operating a motorcycle or any other motor vehicle. Doing so is
dangerous and can result in a traffic accident and serious personal
injury.
• 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 traffic
accident and serious personal injury.

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.
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.)
• 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.
3. Rotate the watch 180 degrees.
4. Press E again to calibrate the second direction.
• 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.
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 E 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.
To perform northerly calibration
B
A
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.
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.

Storage
• 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”.

1. While in the Digital Compass Mode (Normal
screen), hold down A until the upper
display changes to show “–1–”.
2. Press C to start the northerly calibration
procedure.
• 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 E to start the calibration operation.
• 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.
CHANGING THE MEASUREMENT UNITS
You can change the measured values displayed by the watch between the
following units.
Altitude: meters (m) ↔ feet (ft)
Temperatures: Celsius (°C) ↔ Fahrenheit (°F)
Barometric Pressure:
hecto-pascals/millibars (hPa/mb) ↔ inchesHg (inHg)
Some countries call to this unit as hecto-pascal (hPa), while other
countries call it millibars (mb). It really makes no difference, because
1 hPa = 1 mb. In this manual, we will refer to hPa/mb or hPa (mb).
Important!
• Certain measurement functions are automatically terminated when you
change the measurement units. Be sure that you perform this operation
before starting actual measurements.
• Changing the altitude unit of measurement automatically switches off the
altitude alarm, and sets the alarm’s value to zero.
• Changing the barometric pressure unit of measurement automatically restarts
the barometric pressure graph from a new value.
• Changing any of the units of measurement immediately starts to display
newly measured data in the unit you specify. It also affects the unit of
measurement for any data already stored in memory.

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.
Memory measurements are taken independently of Altimeter Mode
measurements and stored directly into memory (along with temperature
measurements) for later recall. With memory measurement, the watch
continuously performs measurements whenever the minutes in the
Timekeeping Mode reach 00, 15, 30, or 45, until you switch memory
measurements off. The watch continues to take measurements regardless of
whether or not you change modes, so you can keep a running log of altitude
and temperature changes automatically.
Important!
About the memory...
• 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.
The memory item stored by the watch consists of the current altitude, plus the
date, time, and temperature. Data is stored in the same sequence that it is
input.
Memory can hold a total of 50 sets of data, which is enough to store 12 hours
and 15 minutes of memory data. See “To recall altitude measurement data
from memory” for details on how to recall memory data.
Applications
When no reference altitude is preset:
• The watch produces approximate altitude readings.
When a reference altitude is preset:
• Before beginning the climb, set the reference altitude to 0 m at the foot of
the mountain. This makes it possible to determine the difference in altitude
between the reference point and your destination.
• To determine the height of a tall
building, set the reference
altitude to 0 m on the ground
floor. Note, however, that if the
building is pressurized or air
conditioned, you may not be able
to get a good reading.
• To determine the difference in altitude between your house and the another
location, set the reference altitude to 0 m at your house, and then check the
reading when you arrive at the other location.
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”).
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 (20 feet), and the measurement range is 0 to 6,000 m
(0 to 19,680 feet).
• The measured altitude may be a negative value in cases where there is a
reference altitude value set or because of certain atmospheric conditions.
Important!
Further memory measurements become impossible
whenever memory is full. If you try to perform Memory
measurement while memory is full, the watch beeps for
three seconds and the message FULL appears on the
display. Always check the amount of memory remaining
before starting memory measurements, and delete data if
necessary.

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 air pressure. Because of this, we recommend that you set the reference
altitude during your climb whenever one is available.

About the graphic 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

The barometer that is 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.
Example barometer applications
• Before going mountain climbing, you can take readings to find out the
probable upcoming weather.
• You can predict the weather for golf or other outdoor activities.
About barometric measurements
The barometer automatically takes measurements every two hours (starting from
midnight), regardless of what mode you are in. The last measurement result, along

THERMOMETER FUNCTIONS
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.
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.
• Temperature measurement data can be recalled along with altitude
measurement data.
Understanding the temperature screen
1. Use C to enter the Timekeeping Mode.
2. Press D to display the Barometric Pressure/Temperature screen.
• See “Barometric Pressure/Temperature Screen Auto Cancel” .
A falling graph generally means deteriorating
weather.
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.
The following conditions cause the barometric pressure measurement to be
skipped, with the corresponding point on the barometric pressure graph
being left blank.
• Barometric reading that is out of range (460 hPa/mb to 1100 hPa/mb or
13.55 inHg to 32.45 inHg)

QUESTIONS & ANSWERS
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.
Question: What causes the Digital Compass to produce
different readings at the same location?
Answer:
• 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.
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.
Question: Why am I having problems performing Digital
Compass operations indoors?
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.
Question: How does the altimeter work?
Answer: Generally, air 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, air pressure, and temperature.

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.

• Be sure to recalibrate at Point B if changing weather conditions produce
altitude reading errors.
• The following conditions will prevent you from obtaining accurate readings:
Air pressure changes because of changes in the weather
Extreme temperature changes
Subjecting the watch to strong impact
Precautions Concerning Simultaneous Measurement of Altitude and
Temperature
Though you can perform altitude and temperature measurements at the
same time, you should remember that each of these measurements require
different conditions for best results. With temperature measurement, it is best
to remove the watch from your wrist in order to eliminate the effects of body
heat. In the case of altitude measurement, on the other hand, it is better to
leave the watch on your wrist, because doing so keeps the watch at a
constant temperature, which contributes to more accurate altitude
measurements.
The following describes what you should do to give priority to either altitude
or temperature.
• To give altitude measurement priority, leave the watch on your wrist or in
any other location where the temperature of the watch is kept constant.
• To give temperature measurement priority, remove the watch from your
wrist and allow it to hand freely from your bag or in another location where
it is not exposed to direct sunlight.
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 barometric 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.

When you are out hiking or mountain climbing, calibrate the altimeter using
an altitude value from another source (a signpost or map, for example). Do
this just before you start your altitude measurements.
• The measurement functions built into this watch are not intended for
use in taking measurements that require professional or industrial
precision. Values produced by this watch should be considered as
reasonably accurate representations only.
• When engaging in mountain climbing or other activities in which losing
your way can create a dangerous or life-threatening situation, always
be sure to use a second compass to confirm direction readings.
• CASIO COMPUTER CO., LTD. assumes no responsibility for any loss,
or any claims by third parties that may arise through the use of this watch.
