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. Do not operate the crown or buttons while your watch is
submersed in water or wet. Avoid wearing your watch while in the bath. Do not
wear your watch while in a heated swimming pool, sauna, or any other high
temperature/high humidity environment. 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 3519
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.
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. 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 Replacement
Leave battery replacement up to your original retailer or authorized CASIO
service center.
Have the battery replaced only with the type specified in the
“Specifications”. Use of a different battery type can cause malfunction.
When replacing the battery, also request a check for proper water resistance.
Ornamental resin components may become worn, cracked, or bent over time when
subjected to normal daily use. Note that if cracking or any other abnormality
indicating possible damage is noticed in a watch submitted for battery
replacement, your watch will be returned with an explanation of the
abnormality, without the requested servicing being performed.
Initial Battery
The battery that comes loaded in your watch when you purchase it is used for
function and performance testing at the factory.
The test battery may go dead quicker than the normally rated battery life
noted in the “Specifications”. Note that you will be charged for replacement
of this battery, even if replacement is required within your watch’s warranty
period.
Low Battery Power
Low battery power is indicated by large timekeeping error, by dim display
contents, or by a blank display.
Operation while battery power is low can result in malfunction. Replace the
battery as soon as possible.
