●
Do not use your watch for scuba diving or
other types of diving that requires air tanks.
●
Watches that do not have WATER RESIST
or WATER RESISTANT marked on the
back cover are not protected against the
effects of sweat. Avoid using such a watch
under conditions where it will be exposed to
large amounts of sweat or moisture, or to
direct splashing with water.
●
Even if a watch is water resistant, note the
usage precautions described below. Such
types of use reduce water resistance
performance and can cause fogging of the
glass.
ー
Do not operate the crown or buttons while
your watch is submersed in water or wet.
ー
Avoid wearing your watch while in the
bath.
ー
Do not wear your watch while in a heated
swimming pool, sauna, or any other high
temperature/high humidity environment.
ー
Do not wear your watch while washing
your hands or face, while doing
housework, or while performing any other
task that involves soaps or detergents.
●
After submersion in seawater, use plain
water to rinse all salt and dirt from your
watch.
●
To maintain water resistance, have the
gaskets of your watch replaced periodically
(about once every two or three years).
●
A trained technician will inspect your watch
for proper water resistance whenever you
have its battery replaced. Battery
replacement requires the use of special
tools. Always request battery replacement
from your original retailer or from an
authorized CASIO service center.
●
Some water-resistant watches come with
fashionable leather bands. Avoid
swimming, washing, or any other activity
that causes direct exposure of a leather
band to water.
●
The inside surface of the watch glass may
fog when the watch is exposed to a sudden
drop in temperature. No problem is
indicated if the fogging clears up relatively
quickly. Sudden and extreme temperature
changes (such as coming into an air
conditioned room in the summer and
standing close to an air conditioner outlet,
or leaving a heated room in the winter and
allowing your watch to come into contact
with snow) can cause it to take longer for
glass fogging to clear up. If glass fogging
does not clear up or if you notice moisture
inside of the glass, immediately stop using
your watch and take it to your original
retailer or to an authorized CASIO service
center.
●
Your water-resistant watch has been tested
in accordance with International
Organization for Standardization
regulations.
●
Band
●
Tightening the band too tightly can cause
you to sweat and make it difficult for air to
pass under the band, which can lead to skin
irritation. Do not fasten the band too tightly.
There should be enough room between the
band and your wrist so you can insert your
finger.
●
Deterioration, rust, and other conditions can
cause the band to break or come off of your
watch, which in turn can cause band pins to
fly out of position or to fall out. This creates
the risk of your watch falling from your wrist
and becoming lost, and also creates the risk
of personal injury. Always take good care of
your band and keep it clean.
●
Immediately stop using a band if you even
notice any of the following: loss of band
flexibility, band cracks, band discoloration,
band looseness, band connecting pin flying
or falling out, or any other abnormality. Take
your watch to your original retailer or to a
CASIO service center for inspection and
repair (for which you will be charged) or to
have the band replaced (for which you will
be charged).
Watch Operation Guide 3513

●
Temperature
●
Never leave your watch on the dashboard
of a car, near a heater, or in any other
location that is subject to very high
temperatures. Do not leave your watch
where it will be exposed to very low
temperatures. Temperature extremes can
cause your watch to lose or gain time, to
stop, or otherwise malfunction.
●
Leaving your watch in an area hotter than
+60 °C (140 °F) for long periods can lead to
problems with its LCD. The LCD may
become difficult to read at temperatures
lower than 0 °C (32 °F) and greater than
+40 °C (104 °F).
●
Impact
●
Your watch is designed to withstand impact
incurred during normal daily use and during
light activity such as playing catch, tennis,
etc. Dropping your watch or otherwise
subjecting it to strong impact, however, can
lead to malfunction. Note that watches with
shock-resistant designs (G-SHOCK,
BABY-G, G-MS) can be worn while
operating a chain saw or engaging in other
activities that generate strong vibration, or
while engaging in strenuous sports
activities (motocross, etc.)
●
Magnetism
●
Though operation of your watch normally is
not affected by magnetism, its accuracy
may be affected if the watch itself becomes
magnetized. Also, very strong magnetism
(from medical equipment, etc.) should be
avoided because it can cause malfunction
of your watch and damage to electronic
components.
●
Electrostatic Charge
●
Exposure to very strong electrostatic
charge can cause your watch to display the
wrong time. Very strong electrostatic
charge even can damage electronic
components.
●
Electrostatic charge can cause the display
to go blank momentarily or cause a rainbow
effect on the display.
●
Chemicals
●
Do not allow your watch to come into
contact with thinner, gasoline, solvents,
oils, or fats, or with any cleaners, adhesives,
paints, medicines, or cosmetics that contain
such ingredients. Doing so can cause
discoloration of or damage to the resin
case, resin band, leather, and other parts.
●
Storage
●
If you do not plan to use your watch for a
long time, thoroughly wipe it free of all dirt,
sweat, and moisture, and store it in a cool,
dry place.
●
Resin Components
●
Allowing your watch to remain in contact
with other items or storing it together with
other items for long periods while it is wet
can cause color on resin components to
transfer to the other items, or the color of the
other items to transfer to the resin
components of your watch. Be sure to dry
off your watch thoroughly before storing it
and make sure it is not in contact with other
items.
●
Leaving your watch where it is exposed to
direct sunlight (ultraviolet rays) for long
periods or failure to clean dirt from your
watch for long periods can cause it to
become discolored.
●
Friction caused by certain conditions
(strong external force, sustained rubbing,
impact, etc.) can cause discoloration of
painted components.
●
If there are printed figures on the band,
strong rubbing of the printed area can cause
discoloration.
●
Leaving your watch wet for long periods can
cause fluorescent color to fade. Wipe the
watch dry as soon as possible after it
becomes wet.
●
Semi-transparent resin parts can become
discolored due to sweat and dirt, and if
exposed to high temperatures and humidity
for long periods.
●
Daily use and long-term storage of your
watch can lead to deterioration, breaking, or
bending of resin components. The extent of
such damage depends on usage conditions
and storage conditions.
●
Leather Band
●
Allowing your watch to remain in contact
with other items or storing it together with
other items for long periods while it is wet
can cause the color of the leather band to
transfer to the other items or the color of the
other items to transfer to the leather band.
Be sure to dry off your watch thoroughly with
a soft cloth before storing it and make sure
it is not in contact with other items.
●
Leaving a leather band where it is exposed
to direct sunlight (ultraviolet rays) for long
periods or failure to clean dirt from a leather
band for long periods can cause it to
become discolored.
CAUTION:
Exposing a leather band to rubbing or dirt
can cause color transfer and discoloration.
●
Metal Components
●
Failure to clean dirt from metal components
can lead to formation of rust, even if
components are stainless steel or plated. If
metal components exposed to sweat or
water, wipe thoroughly with a soft,
absorbent cloth and then place the watch in
a well-ventilated location to dry.
●
Use a soft toothbrush or similar tool to scrub
the metal with a weak solution of water and
a mild neutral detergent, or with soapy
water. Next, rinse with water to remove all
remaining detergent and then wipe dry with
a soft absorbent cloth. When washing metal
components, wrap the watch case with
kitchen plastic wrap so it does not come into
contact with the detergent or soap.
Watch Operation Guide 3513

●
Bacteria and Odor Resistant Band
●
The bacteria and odor resistant band
protects against odor generated by the
formation of bacteria from sweat, which
ensures comfort and hygiene. In order to
ensure maximum bacteria and odor
resistance, keep the band clean. Use an
absorbent soft cloth to thoroughly wipe the
band clean of dirt, sweat, and moisture. A
bacteria and odor resistant band
suppresses the formation of organisms and
bacteria. It does not protect against rash
due to allergic reaction, etc.
●
Liquid Crystal Display
●
Display figures may be difficult to read when
viewed from an angle.
●
Watch with Data Memory
●
Allowing the battery to go dead, replacing
the battery, or having your watch repaired
can cause all data in watch memory to be
lost. Note that CASIO Computer Co., Ltd.
assumes no responsibility for any damages
or losses caused by data lost due to
malfunction or repair of your watch,
replacement of the battery, etc. Be sure to
keep separate written copies of all
important data.
●
Watch Sensors
●
A watch sensor is a precision instrument.
Never try to take it apart. Never try to insert
any objects into the openings of a sensor,
and take care to ensure that dirt, dust, or
other foreign matter does not get into it.
After using your watch where it has been
immersed in saltwater, rinse it thoroughly
with fresh water.
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 your
watch or its malfunction.
User Maintenance
●
Caring for Your Watch
Remember that you wear your watch next to
your skin, just like a piece of clothing. To
ensure your watch performs at the level for
which it is designed, keep it clean by
frequently wiping with a soft cloth to keep your
watch and band free of dirt, sweat, water and
other foreign matter.
●
Whenever your watch is exposed to sea
water or mud, rinse it off with clean fresh
water.
●
For a metal band or a resin band with metal
parts, use a soft toothbrush or similar tool to
scrub the band with a weak solution of water
and a mild neutral detergent, or with soapy
water. Next, rinse with water to remove all
remaining detergent and then wipe dry with
a soft absorbent cloth. When washing the
band, wrap the watch case with kitchen
plastic wrap so it does not come into contact
with the detergent or soap.
●
For a resin band, wash with water and then
wipe dry with a soft cloth. Note that
sometimes a smudge like pattern may
appear on the surface of a resin band. This
will not have any effect on your skin or
clothing. Wipe with a cloth to remove the
smudge pattern.
●
Clean water and sweat from a leather band
by wiping with a soft cloth.
●
Not operating a watch crown, buttons, or
rotary bezel could lead to later problems
with their operation. Periodically rotate the
crown and rotary bezel, and press buttons
to maintain proper operation.
●
Dangers of Poor Watch Care
Rust
●
Though the metal steel used for your watch
is highly rust-resistant, rust can form if your
watch is not cleaned after it becomes dirty.
ー
Dirt on your watch can make it impossible
for oxygen to come into contact with the
metal, which can lead to breakdown of
the oxidization layer on the metal surface
and the formation of rust.
●
Rust can cause sharp areas on metal
components and can cause band pins to fly
out of position or to fall out. If you ever notice
any abnormality immediately stop using
your watch and take it to your original
retailer or to an authorized CASIO service
center.
●
Even if the surface of the metal appears
clean, sweat and rust in crevasses can soil
the sleeves of clothing, cause skin irritation,
and even interfere with watch performance.
Premature Wear
●
Leaving sweat or water on a resin band or
bezel, or storing your watch an area subject
to high moisture can lead to premature
wear, cuts, and breaks.
Skin Irritation
●
Individuals with sensitive skin or in poor
physical condition may experience skin
irritation when wearing a watch. Such
individuals should keep their leather band
or resin band particularly clean. Should you
ever experience a rash or other skin
irritation, immediately remove your watch
and contact a skin care professional.
Battery
●
The special rechargeable battery used by
your watch is not intended to be removed or
replaced by you. Use of a rechargeable
battery other than the special one specified
for your watch can damage your watch.
●
The rechargeable (secondary) battery is
charged when the solar panel is exposed to
light, so it does not require regular
replacement as the primary battery
requires. Note, however, that long use or
operating conditions can cause the
capacity or charging efficiency of the
rechargeable battery to deteriorate. If you
feel that the amount of operation provided
by charging is too short, contact your
original retailer or CASIO service center.

Digital Compass Reading
Precautions
Location During Use
Taking readings near sources of strong
magnetism can cause reading error. Keep the
watch away from the following types of items.
Permanent magnets (magnetic accessories,
etc.), metal objects, high-voltage wires, aerial
wires, electrical household appliances (TVs,
computers, cellphones, etc.)
●
Note that correct direction readings are not
possible indoors, especially inside of
reinforced concrete structures.
●
Accurate direction readings are not
possible on electric trains, on boats, on
aircraft, etc.
Storage Location
Exposure of the watch to magnetism can
affect the accuracy of digital compass
readings. Keep the watch away from the types
of items below.
Permanent magnets (magnetic accessories,
etc.), metal objects, electrical household
appliances (TVs, computers, cellphones, etc.)
Altitude
Measurement
The watch takes altitude readings and
displays results based on air pressure
measurements taken by a built-in pressure
sensor.
Important!
●
The altitude readings displayed by the
watch are relative values that are
calculated based on barometric
pressure measured by the watch’s
pressure sensor. This means that
barometric pressure changes due to
weather can cause altitude readings
taken 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 regularly calibrate its readings
in accordance with local altitude
(elevation) indications.

Calibrating Altitude
Readings (Offset)
To minimize the difference between locally
indicated and measured values, you should
update the reference altitude value (offset)
before setting off and during treks or any other
activities where you take altitude readings.
Also, you can ensure accurate measurements
by checking a map local altitude indications or
some other source for your current location’s
altitude, and regularly calibrating watch
readings with the latest information while
mountain climbing.
Note
●
You can find out the altitude at your
current location from signs, maps, on
the Internet, etc.
●
Differences between actual altitude
and watch readings can be caused by
the factors below.
ー
Changes in barometric pressure
ー
Changes in temperature caused by
variations in barometric pressure
and by elevation
●
Though altitude readings can be taken
without calibration, doing so may
produce readings that are very

Altitude Reading
Precautions
Effects of Temperature
When taking altitude readings, take the steps
below to keep the watch at as stable a
temperature as possible. Changes in
temperature can affect altitude readings.
●
Take readings with the watch on your wrist.
●
Take readings in an area where
temperature is stable.
Altitude Readings
●
Do not use this watch while skydiving, hang
gliding, paragliding, gyrocopter flying, glider
flying, or engaged in other activities where
altitude changes suddenly.
●
Altitude readings produced by this watch
are not intended for special-purpose or
industrial level use.
●
In an aircraft, the watch measures the in-
cabin pressurized air pressure, so readings
will not match altitudes announced by the
crew.
Altitude Readings (Relative Altitude)
This watch uses International Standard
Atmosphere (ISA) relative altitude data
defined by the International Civil Aviation
Organization (ICAO). Barometric pressure
generally becomes lower as altitude
increases.
Correct measurement may not be possible
under the conditions below.
●
During unstable atmospheric conditions
●
During sudden temperature changes
●
After the watch has been subjected to
strong impact
Barometric Pressure
and Temperature

Checking Changes in
Barometric Pressure Over
Time
Your watch shows a graph of barometric
pressure readings taken at two-hour intervals.
You can view barometric pressure readings
for the past 42 hours. The square (

Predicting Upcoming Weather
A trend
like this:
Means this:
Rising barometric pressure,
which indicates that upcoming
weather probably will be fair.
Falling barometric pressure,
which indicates that upcoming
weather probably will be bad.
Note
●
Large changes in barometric pressure
and/or temperature can cause past
data readings to be plotted outside of
the visible area of the graph. Though
plots are not visible, the data is still
maintained in watch memory.
Checking the Change
Between Two Barometric
Pressure Readings
(Barometric Pressure
Differential)
In the Barometer/Temperature Mode, the
display shows the current measured value,
and a graphic indicator of the differential
between the automatically measured current
value and the latest value measured at two-
hour intervals.

Unit: hPa
Note
●
The barometric pressure differential
graphic indicator will not be displayed
if the barometric pressure differential
exceeds ±10 hPa, or if the barometric
pressure measurement value exceeds
the measurement range.
Sudden Barometric Pressure
Change Indications
Whenever the watch detects a significant
change in air pressure readings (due to
sudden ascent or descent, or to the passage
of a low-pressure or high-pressure area), it will
beep to let you know. An arrow will also flash
on the display at this time if the watch is in the
Barometer/Temperature Mode, or if it is in the
Timekeeping Mode with the barometric
pressure graph displayed. The arrow that
appears shows the direction of the pressure
change. These alerts are called “Barometric
Pressure Change Indications”.
This
indicator:
Means this:
Sudden drop in pressure
Sudden rise in pressure
Sustained rise in pressure,
shifting to a fall
Sustained fall in pressure, shifting
to a rise
Important!
●
To ensure correct barometric pressure
change indicator operation, enable it in
a location where the altitude is
constant (such as a lodge, camp area,
or on the ocean).
●
A change in altitude causes a change
in air pressure. Because of this, correct
readings are impossible. Do not take
readings while ascending or
descending a mountain, etc.

Correcting Measured
Barometric Pressure and
Temperature Values (Offset)
The watch’s built-in pressure sensor and
temperature sensor are adjusted at the factory
and normally do not require correction.
However, you can correct the displayed value
if you notice major errors in readings.
Important!
●
The watch will not be able to produce
correct barometric pressure readings if
you make a mistake during the
correction procedure. Check to ensure
that the values you use for calibration
produces correct pressure and
temperature readings.
●
Before adjusting the temperature
sensor, remove the watch from your
wrist and leave it in the area where you
plan to measure temperature for about
20 or 30 minutes to allow the case
temperature to become the same as
the air temperature.

Troubleshooting
Altitude Measurement
Q1
Readings produce different results at
the same location.
Watch readings are different from
altitude information available from
other sources.
Correct altitude readings are not
possible.
Relative altitude is calculated based on
changes in barometric pressure measured by
the watch’s pressure sensor. This means that
barometric pressure changes can cause
readings taken 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 regularly
calibrate its readings in accordance with local
altitude (elevation) indications.
l
Calibrating Altitude Readings (Offset)
Q2
[ERR] appears during measurement.
There may be a problem with the sensor. Try
taking another measurement.
If [ERR] keeps appearing after multiple
measurement attempts, contact a CASIO
service center or your original retailer.
Digital Compass
Q1
The entire display is flashing.
Abnormal magnetism has been detected.
Move away from any potential source of
strong magnetism and try taking a reading
again.
l
Digital Compass Reading Precautions
●
If the display flashes again, it could mean
that the watch itself has become
magnetized. Move away from any potential
source of strong magnetism, perform 2-
point calibration, and then try taking a
reading again.
l
Calibrating Compass Readings
Q2
[ERR] appears during measurement.
There is a problem with the sensor or there
may be a source strong magnetic force
nearby. Move away from any potential source
of strong magnetism and try taking a reading
again. If [ERR] keeps appearing after multiple
measurement attempts, contact a CASIO
service center or your original retailer.
l
Digital Compass Reading Precautions
Q3
[ERR] appears following 2-point
calibration.
[ERR] on the display could indicate a sensor
problem.
●
If [ERR] disappears after about one second,
try performing 2-point calibration again.
●
If [ERR] keeps appearing after multiple
attempts, contact a CASIO service center or
your original retailer.
Q4
Direction information indicated by the
watch is different from that indicated
by a backup compass.
Move away from any potential source of
strong magnetism, perform 2-point
calibration, and then try taking a reading
again.

Q5
Readings at the same location
produce different results.
Cannot take readings indoors.
Move away from any potential source of
strong magnetism and try taking a reading
again.

Barometric Pressure
Measurement
Q1
The barometric pressure differential
graphic is not displayed after
barometric pressure measurement.
The barometric pressure differential graphic is
not displayed if the barometric pressure
measurement value exceeds the allowable
measurement range (260hPa to 1,100hPa) or
if the barometric pressure differential exceeds
±10hPa. If [ERR] is displayed, there may be a
problem with the sensor.

Q1
The watch does not work even
though it is exposed to light.
The watch stops operating whenever the
battery goes dead. Keep the watch exposed
to light until it recharges sufficiently.
l
Checking the Charge Level
Q2
[H], [M], and [L] are flashing on the
display.
The watch is in the charge recovery mode.
Wait until the recovery process is complete
(about 15 minutes). The watch will recover
more quickly if you place it in a brightly lit
location.
●
If an alarm, hourly time signal, illumination
and/or other power-intensive functions are
used within a short period of time, the
charging capacity of the battery will drop
and cause the watch to go into a charge
recovery mode. Function availability will be
temporarily limited, but functionality will
return after the battery recovers.
l
Checking the Charge Level
Q3
[CHG] is flashing on the display.
The charge level of the watch is extremely low.
Immediately expose the watch to light to
charge it.
