• 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. E-45...
• 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.
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.
Impact • Your watch is designed to withstand impact incurred during normal daily use and light activity such as playing catch, tennis, etc. Dropping the 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 engage in strenuous sports activities (motocross, etc.).
Chemicals • Do not allow the 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 case, resin band, leather band, and other parts.
• Semi-transparent resin parts can become discolored due to sweat and dirt, and if exposed to high temperatures for long periods. • Contact an authorized CASIO Service Center to have resin components replaced. Note that you will be charged for replacement costs.
• 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. Important! • Subjecting a natural leather or imitation leather band to rubbing or dirt can cause color transfer and discoloration.
• 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 this product or its malfunction.
• Should your band become badly cracked or worn, be sure to have it replaced with a new one. Request band replacement from your original retailer or an authorized CASIO Service Center. Note that you will be charged for band replacement costs, even if your watch is still covered by its warranty.
Dangers of Poor Watch Care Rust • Though the stainless steel used for the watch is highly rust-resistant, rust can form if the watch is not cleaned after it becomes dirty. Failure of oxygen to come into contact with the metal because it is dirty causes breakdown of the oxidization layer on the metal surface, which leads to the formation of rust.
Battery Replacement • Leave battery replacement up to your original retailer or authorized CASIO Service Center. • Have the battery replaced only with the type specified by in this manual. Use of another type of battery can cause malfunction. • When replacing the battery, also request a check for proper water resistance. Note that you will be charged separately for water resistance inspection.
