• Do not use this 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, do not operate its buttons or
crown while it is submersed in water or wet.
• Even if a watch is water-resistant, avoid wearing it in the bath or
in areas where detergents (soap, shampoo, etc.) are being used.
Such conditions can reduce water resistance.
• After submersion in seawater, use plain water to rinse all salt and
dirt from the watch.
• To maintain water resistance, have the gaskets of your watch
replaced periodically (about once every two or three years).
• A trained technician will know how to check 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. If the fogging does not
clear or if water has gotten into the watch, take it in for repair
immediately.
• Continued use of the watch with water inside can result in damage
to electronic and mechanical components, the face of the watch,
etc.
• Your water-resistant watch has been tested in accordance with the
International Organization for Standardization regulations ISO2281
and FTC (USA) “GUIDE FOR THE WATCH INDUSTRY.” Guide 5.
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, or corrosion of the band can cause it to break,
which may result in the watch falling off your wrist and becoming
lost. Be sure to take good care of the band and keep it clean.
Should you notice any breakage, discoloration, looseness or
other problem with the band, immediately contact your original
retailer or an authorized CASIO Service Center to have it checked,
repaired, or replaced. Note that you will be charged for any repair
or replacement of the band.
Temperature
• Never leave the 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 the watch where it will be exposed to very low
temperatures, either. Temperature extremes can cause the watch
to lose or gain time, to stop, or otherwise malfunction.
