    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 or a soft cloth 
    moistened in a solution of water and a mild neutral detergent.  Never 
    use volatile agents (such as benzene, 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 contact 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 contact with any other surface while wet can cause 
    discoloration of fluorescent colors.  Be sure to keep moisture from 
    fluorescent surfaces and avoid contact 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.
