Radio-controlled Atomic Timekeeping Precautions • Strong electrostatic charge can cause the time setting to be thrown off. • The time calibration signal bounces off the ionosphere. Because of this, such factors as changes in the reflectivity of the ionosphere, as well as movement of the ionosphere to higher altitudes due to seasonal atmospheric changes or the time of day may change the reception range of the signal and make reception temporarily impossible.
• If you are in an area where proper time calibration signal reception is impossible, the watch keeps the time with the precision noted in “Specifications”. • If you have problems with proper time calibration signal reception or if the time setting is wrong after signal reception, check your current city code, DST (summer time) (page E-58).
• When a China time zone is selected, the watch receives the time calibration signal transmitted from China (Shangqiu City). • When your Home City is LIS, LON, MAD, PAR, ROM, BER, STO, ATH, MOW (which can receive both the Anthorn and Mainflingen signals), the watch first tries to pick up the signal it last received successfully. If that fails, it tries the other signal.
Initial Screens When you enter the World Time Mode or Alarm Mode, the data you were viewing when you last exited the mode will appear 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. In the range of 00 to 29, the seconds are reset to 00 without changing the minutes. • The year can be set in the range of 2000 to 2099.
Illumination Precautions • Illumination may be hard to see when viewed under direct sunlight. • Illumination turns off automatically whenever an alarm sounds. • Frequent use of illumination runs down the battery. Auto light switch precautions • The auto light switch is turned off automatically whenever battery power is at Level 4 (CHG) (page E-51). • Avoid wearing the watch on the inside of your wrist. Doing so causes the auto light switch to operate when it is not needed, which shortens battery life.
• Static electricity or magnetic force can interfere with proper operation of the auto light switch. If illumination does not turn on, try moving the watch back to the starting position (parallel with the ground) and then tilt it back toward you again. If this does not work, drop your arm all the way down so it hangs at your side, and then bring it back up again. • Under certain conditions, illumination may not turn on until about one second after you turn the face of the watch towards you.

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.
• 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 the watch in for repair immediately.
• 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.
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.).
• Electrostatic charge can cause the display to go blank momentarily or cause a rainbow effect on the display. 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.
• Leaving the watch where it is exposed to direct sunlight (ultraviolet rays) for long periods or failure to clean dirt from the watch for long periods can cause it to become discolored. • Friction caused by certain conditions (frequent 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.
Natural Leather and Imitation Leather Bands • Allowing the watch to remain in contact with other items or storing it together with other items while it is wet for long periods can cause the color of the other items to transfer to the natural leather or imitation leather band 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.
• 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. Bacteria and Odor Resistant Band • The bacteria and odor resistant band protects against odor generated by the formation of bacteria from sweat, which ensures good comfort and hygiene. In order to ensure maximum bacteria and odor resistance, keep the band clean.
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.
• Remember that you wear your watch next to your skin, just like a piece of clothing. Because of this, you should always keep your watch clean. Use a soft, absorbent cloth to wipe off any dirt, sweat, water, or other foreign matter from the case and band. 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.
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, or switch to a metal band. Should you ever experience a rash or other skin irritation, immediately remove the watch and contact a skin care professional. Battery • The special rechargeable (secondary) battery used by your watch is not intended to be removed or replaced by you.
