Operation Guide 3220
E-89
•
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.
E-88
•
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.

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.
E-86
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.
E-85
•
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.
E-84
•
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.
E-83
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.
E-82
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.
E-81
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.)
E-80
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).
