OPUM-E
E-22
  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).
E-23
  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.
E-24
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).
E-25
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-26
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.
E-27
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-28
  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-29
  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-30
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.

E-31
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.

E-32
 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-33
  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.
E-34
  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.
E-35
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 and by charging with the charger, 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.
