Water Resistance This watch will withstand the ingress of water at the static pressure indicated on its case (50, 100, or 200 meters), and immersion in salt water at the depth indicated. Note, however, that dynamic pressure generated by movement underwater is greater than static pressure. Note the following. *Rank Case Designation Splashes Swimming, Smorkeling Scuba rain, etc. car-washing diving, etc. diving etc. I - No No No No II WATER RESISTANT Yes No No No III 50 M WATER RESISTANT Yes Yes No No IV 100 M WATER RESISTANT Yes Yes Yes No V 200 M WATER RESISTANT 300 M WATER RESISTANT Yes Yes Yes Yes NOTES: I Not water-resistant. Avoid all moisture. III Do not operate buttons underwater. IV Button operation underwater is allowed, but do not operate recessed buttons. If watch is exposed to salt water, wash thoroughly and wipe dry. V Usable while scuba diving (except at depths that require helium-oxygen gas). Your water-resistant watch has been tested in accordance with the International Organization for Standardization regulations IS02281 and FTC (USA) "GUIDE FOR THE WATCH INDUSTRY", Guide 5. Some water-resistant watches feature leather bands. Do not wear such a model during swimming or any other activity during which the band is immersed in water. Care of your watch Never try to open the case or remove its back cover. You should have the rubber seal that keeps out water and dust replaced every 2 to 3 years. Should moisture appear inside the watch, have it checked immediately by your dealer or CASIO distributor. Avoid exposing the watch to temperature extremes. Though the watch is designed to withstand normal use, you should avoid rough use or dropping the watch. Do not fasten the band too tightly. You should be able to insert your finger between the band and your wrist. To clean the watch and band, use a dry soft cloth moistened in a solution of water and a mild neutral detergent. Never use volatile agents (such as benzine, thinner, spray cleaners, etc.). Store your watch in a dry place when you are not using it. Avoid exposing the watch to gasoline, cleaning solvents, aerosol sprays, adhesive agents, paint, etc. Chemical reactions with such agents will destroy seals, case and finish. Some models feature silk screen printing on their bands. Be careful when cleaning such bands so that you do not rub on the printed designs too hard. For watches equipped with resin bands... You may notice a whitish powdery substance on the band. This substance will not harm your skin or clothing, and can be removed by simply wiping it with a cloth. Leaving the resin band wet with sweat or water, or storing it in an area subjected to high humidity can cause the band to deteriorate, cut, or crack. To ensure long life for the resin band, wipe off dirt or water with a soft cloth as soon as possible. For watches equipped with fluorescent bands and cases... Long-term exposure to direct sunlight can cause fluorescent coloring to fade. Long-term contract with moisture can cause fluorescent coloring to fade. Be sure to wipe all moisture from the surface of the watch as soon as possible. Long-term contract with any other surface while wet can cause discoloration of fluorescent colors. Be sure to keep moisture from fluorescent surfaces and avoid contract with other surfaces. Strongly rubbing a printed fluorescent surface with another surface can cause the color of the printing to transfer to the other surface. (PH 11/9/95)
