●
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 3565

●
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 a digital watch normally is not
affected by magnetism, very strong
magnetism (from medical equipment, etc.)
should be avoided because it can cause
malfunction 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.
●
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.

Step Count
You can use your watch to keep track of your

●
Step Reminder
Studies suggest that sitting too much is bad
for the health.
Step Reminder displays an indicator and
sounds an alert when it determines you have
not walked enough during a specific period.
This is valuable feedback that helps achieve
your exercise goals.
If the watch performs a Step Reminder alert
operation, get up and walk for about five
minutes.
Counting Steps
If you are wearing the watch correctly, the
watch will count your steps as you walk or
engage in your normal daily activities.
Important!
●
Since this watch is a wrist-worn device,
it may detect non-step movements and
count them as steps. Also, abnormal
arm movements while walking may
cause a miss count of steps.
●
Getting Ready
To enable the most accurate step count, wear
the watch with the face on the outside of your
wrist and tighten the band securely. A loose
band may make it impossible to obtain correct
measurement.

5,000 steps
10,000 steps (goal attained)
Note
●
The step count can show a value up to
999,999 steps. If the step count
exceeds 999,999, the maximum value
(999,999) remains on the display.
●
To prevent miscounts, the displayed
count does not increase for about 18
seconds after you start walking. After
you have been walking for about 18
seconds, the correct count appears,
including the steps you took during the
previous 18 seconds.
●
The step count is reset to zero at
midnight each day.
●
To save power, step counting stops
automatically if the watch is removed
from the wrist and no movement is
detected for about two to three
minutes.

Counting Steps
Q2
The step count does not increase.
To avoid miscounting non-walking
movements, the step count or distance value
is not displayed for about 18 seconds after you

It appears only after you have continued
walking for about 18 seconds, with the number
of steps you took during the first 18 seconds
included in the total.
Q3
[ERR] appears when counting steps.
