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 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.
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 covered only
partially.

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 current barometric pressure value displayed in the Barometer/
Thermometer Mode.
• Pressure differential is indicated in the range of ±5 hPa, in 1-hPa units.
• The barometric pressure differential pointer is not displayed when the
displayed current barometric value is outside of the allowable measurement
range (260 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.

reappear as soon as the measured barometric pressure is within the
allowable range.
• Temperature is displayed in units of 0.1°C (or 0.2°F).
• The displayed temperature value changes to xx.x °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 reappear as soon as the measured
temperature is within the allowable range.
• In some areas, barometric pressure is expressed in millibars (mb) instead
of hectopascals (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 select
the temperature, barometric pressure, and altitude units”.
• See “Barometer and Thermometer Precautions” for important precautions.
Barometric Pressure Graph
Barometric pressure indicates changes in the atmosphere. By monitoring
these changes you can predict the weather with reasonable accuracy.
This watch takes barometric pressure measurements automatically every two
hours (at the top of each even-numbered hour), regardless of its current
mode. 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 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.

About Barometric and Temperature Measurements
• Barometric pressure and temperature measurement operations are
performed as soon as you enter the Barometer/Thermometer Mode. After
that, they are taken at five-second intervals.
• You also can perform a barometric pressure and temperature measurement
at any time by pressing B in the Barometer/Thermometer Mode.
Altimeter
The watch’s altimeter uses a pressure sensor to detect current air pressure,
which is then used to estimate the current altitude based on ISA (International
Standard Atmosphere) preset values. You also can specify a reference
altitude, which the watch will use to calculate your current altitude based on
the value you specify. You can configure an altimeter alarm that sounds
whenever the measured altitude reaches a value you preset. Altimeter
functions also include storage of measurement data in memory.
Important!
• This watch estimates altitude based on air pressure. This means that
altitude readings for the same location may vary if air pressure changes.
• The semiconductor pressure sensor used by the watch for altitude
measurements also is affected by temperature. When taking altitude
measurements, make sure the watch is not subjected to temperature
changes.
• To avoid the effect of sudden temperature changes during measurement,
keep the watch on your wrist in direct contact with your skin.
• Do not rely upon this watch for altitude measurements 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 the flight crew.
A falling graph generally means deteriorating weather.

How the Altimeter Measures Altitude
To select the altitude measurement type
The altimeter can measure altitude based on its own preset values, or a
reference altitude specified by you.
Altitude measurement type
You can use the procedure described in this section to display your current
altitude. If you leave the watch in the Altimeter Mode, it will update the
displayed altitude value regularly and indicate reading-to-reading changes in
the altitude graph.
You can select either of the two altitude measurement types described below.
SHORT: Readings at five-second intervals for one hour
LONG: Readings at five-second intervals for the first three minutes followed
by two-minute intervals for approximately nine or 10 hours
• For information about configuring settings for the altitude reading interval
and duration, see “To select the altitude measurement type”.
l l l
4. Press D to toggle the altitude measurement type setting between SHORT
and LONG.
• SHORT: Readings at five-second intervals for one hour
• LONG : Readings at five-second intervals for the first three minutes
followed by two-minute intervals for approximately nine or 10 hours
thereafter
5. Press A to exit the setting screen.
Altitude Records
Storing altitude data in memory creates an altitude record. If a reading is
greater than all of the other altitude readings currently stored in memory, it is
stored in the maximum altitude record. The following describes the contents
of each type of record.
Recording date (year, month, day), time (hour, minutes) and altitude: Up to 40
records
Maximum altitude (including recording date and time): 1 record
• The maximum altitude record shows information about the altitude record
that has the greatest altitude value. The maximum altitude record is
updated any time a reading produces an altitude that is greater than that of
the current maximum altitude record.
To store an altitude record in memory
In the Altimeter Mode, hold down D for about
one second until the watch beeps twice. This
indicates that a record of the altitude reading has
been stored in memory.
• You can recall data in memory using the Data
Recall Mode.
• Note that there is enough memory to store a
total of 40 records. If there are 40 records
already in memory, storing another one deletes
the oldest record automatically to make room
for the new one.
Important!
• The procedure in this section simply displays values indicating your current
altitude, without storing them in watch memory. For information about
recording altitude readings in watch memory, see “Altitude Records”.
To display your current altitude
1. Use C to enter the Data Recall Mode.
2. Use D and B to cycle through the altitude record screens in the

Notes
• Normally, displayed altitude values are based on the watch’s preset
conversion values. You also can specify a reference altitude, if you want.
See “Specifying a Reference Altitude”.
• Altitude is displayed in units of 5 meters (20 feet).
• The measurement range for altitude is –700 to 10,000 meters (–2,300 to
32,800 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.
• The displayed altitude value changes to xxxxx meters (or feet) if a
measured altitude falls outside the measurement range. The altitude value
will be displayed again as soon as the measured altitude is within the
allowable range.
• You can change the measurement unit for displayed altitude values to either
meters (m) or feet (ft). See “To select the temperature, barometric pressure,
and altitude units”.

Displaying Your Current Altitude
l l l l
When you measure altitude using a reference altitude specified by you
After you specify a reference altitude, the watch uses that value to convert the
current measured barometric pressure value to altitude.
• To determine the height of a tall building, for
example, specify zero for the reference
altitude value while you are on the ground
floor. Then when you go to a higher floor, the
altitude displayed by the watch will indicate
the height from the ground floor. Note that
you may not be able to get a good reading if
the building is pressurized or air-conditioned.
• When mountain climbing, you can set the
B
reference value in accordance with a marker
along the way or altitude information from a
A
map. After that, the altitude readings

Questions & Answers
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

• 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.

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 requires
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 hang freely from your bag or in another location where
it is not exposed to direct sunlight. Note that removing the watch from your
wrist can affect pressure sensor readings momentarily.

Question: How does the altimeter work?
Answer: Generally, air pressure and temperature decrease as altitude
increases. This watch bases its altitude measurements on
International Standard Atmosphere (ISA) values stipulated by the
International Civil Aviation Organization (ICAO). These values define
relationships between altitude, air pressure, and temperature.
Except for timekeeping and
the CHG indicator, all
functions and display
indicators are disabled.
All functions disabled.
• The flashing
indicator at Level 3 and the flashing CHG indicator 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 is charged to Level 2 after falling to
Level 5, reconfigure the current time, date, and other settings.
• Display indicators reappear as soon as the battery is charged from Level 4
to Level 2.
• 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.
Recover indicator
• Performing multiple sensor, illumination, or
beeper operations during a short period may
cause RECOV to appear on the display.
Illumination, alarm, countdown timer alarm,
Hourly Time Signal, and sensor operations will
be disabled until battery power recovers.
After some time, battery power will recover and
RECOV will disappear, indicating that the
above functions are enabled again.
• Even if battery power is at Level 1 or Level 2, the Barometer/Thermometer
Mode or Altimeter 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 RECOV appears frequently, it probably means that remaining battery
power is low. Leave the watch in bright light to allow it to charge.
Charging Precautions
Certain charging conditions can cause the watch to become very hot. Avoid
leaving the watch in the areas described below whenever charging its
rechargeable battery.
Also note that 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.
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

• 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.
lll
• 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.
1. Enter the Timekeeping Mode.
2. Hold down A until the seconds start to flash,
which indicates the setting screen.
3. Use C to select the setting screen for the unit
you want to change.
• See step 2 under “To set the time and date”

5. After the settings are the way you want, press A to exit the setting screen.
• 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.
• Under certain conditions, illumination does not turn on until about one
second after you turn the face of the watch towards you. This does not
necessarily indicate malfunction.
• 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.
Barometer and Thermometer Precautions
• The pressure sensor built into this watch measures changes in air
pressure, which you can then apply to your own weather predictions.
However, 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.
Pressure Sensor and Temperature Sensor Calibration
The pressure sensor and temperature sensor built into the watch are
calibrated at the factory and normally require no further adjustment. If you
notice serious errors in the temperature readings produced by the watch, you
can calibrate the sensor to correct the errors.
Important!
• Calibrating the barometric pressure sensor incorrectly 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.
• Calibrating the temperature sensor incorrectly 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.
