Initial Screens When you enter the World Time or Alarm Mode, the data you were viewing when you last exited the mode appears first. Timekeeping • Resetting the seconds to 00 while the current count is in the range of 30 to 59 causes the minutes to be increased by 1.
• The year can be set in the range of 2000 to 2039. • The watch’s built-in full automatic calendar makes allowances for different month lengths and leap years. Once you set the date, there should be no reason to change it except after you have the watch’s batteries replaced. World Time • All World Time Mode times are calculated from the current Home City time in the Timekeeping Mode using UTC time differential values.

Operating Precautions Water Resistance • The following applies to watches with WATER RESIST or WATER RESISTANT marked on the back cover.
• 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.
• 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 the watch 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.
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. • Leaving the watch in an area hotter than +60°C (140°F) for long periods can lead to problems with its LCD.
Magnetism • The hands of analog and combination (analog-digital) watches are moved by a motor that uses magnetic force. When such a watch is close to a device (audio speakers, magnetic necklace, cell phone, etc.) that emits strong magnetism, the magnetism can cause timekeeping to slow down, speed up, or stop, resulting in the incorrect time being displayed. Electrostatic Charge • Exposure to very strong electrostatic charge can cause the watch to display the wrong time.
Storage • If you do not plan to use the watch for a long time, wipe it thoroughly free of all dirt, sweat, and moisture, and store it in a cool, dry place. Resin Components • Allowing the 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 other items to transfer to the resin components of the watch. Be sure to dry off the watch thoroughly before storing it and make sure it is not in contact with other items.
• 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.
Metal Components • Failure to clean dirt from a metal band can lead to formation of rust, even if the band is stainless steel or plated. If the watch is exposed to sweat or water, wipe it thoroughly with a soft, absorbent cloth and then store it in a well-ventilated location to dry. • To clean the band, use a soft toothbrush or similar tool to scrub it with a weak solution of water and a mild neutral detergent. Take care to avoid getting solution on the watch case.
Display • 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.
User Maintenance Caring for Your Watch • A dirty or rusty case or band can soil the sleeve of your clothing, cause skin irritation, and even interfere with watch performance. Be sure to keep the case and band clean at all times. Rust tends to form easily after the watch is exposed to seawater and then left without cleaning. • Sometimes a smudge like pattern may appear on the surface of a resin band. This will not have any affect on your skin or clothing. Wipe the band with a cloth to clean it.
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 batteries replaced only with the type specified by in this manual. Use of other types of batteries can cause malfunction. • When replacing the batteries, also request a check for proper water resistance. Note that you will be charged separately for water resistance inspection.
