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.
Page 38
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.
Page 39
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.
Page 40
• 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.
• 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.

User Maintenance Caring for Your Watch Remember that you wear your watch next to your skin, just like a piece of clothing.

• 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.
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 User’s Guide. Use of a different battery type can cause malfunction. • When replacing the battery, also request a check for proper water resistance.
