  • Using the Stopwatch

    The stopwatch lets you measure elapsed time up to 11 hours, 59 minutes, 59 seconds.You can also correct the position of the stopwatch second hand when necessary.The illustration shows a time of 2 hours, 20 minutes, 40 seconds.Do not try to perform stopwatch operations while the crown is pulled out either tothe first or second click. If you try to press a button, you might accidentally causethe crown to rotate and change the current time or day setting.
    To measure elapsed time
    1. Press A to start the stopwatch.2. Press A to stop the stopwatch.You can resume the measurement operation by pressing A again.3. Press B to reset the stopwatch.
    Adjusting the Stopwatch Second Position
    Use of the stopwatch can cause the starting positions of the stopwatch minute handand second hand to become misaligned. Use the following procedures to check handalignment and to adjust the positions of the hands so they point to 12 o’clock whenthe stopwatch is reset.
    To adjust the positions of the stopwatch hands
    1. Press B to reset the stopwatch, and check the alignment of the stopwatch minutehand and second hand.2. Pull out the crown to the second click.3. Press A to move the stopwatch second hand forward until it points to 12 o’clock.4. If the stopwatch minute hand is aligned correctly, proceed to step 5. If thestopwatch hour hand and stopwatch minute hand are also misaligned, press B sothe stopwatch minute hand jumps to 0.5. After making the adjustments you want, push the crown back in to its normal position.Note that pulling the crown out also stops the timekeeping second hand. Afterperforming the above procedure, you should also adjust the timekeeping setting.

    To set the time

    1. Pull out the crown to the second click.This causes the second hand to stop.2. Set the hands by rotating the crown.Move the minute hand four or fiveminutes past the time you want toset, and then back it up to the propersetting.
    3.
    Push the crown back in to the normalposition to restart timekeeping.

    To set the day

    1. Pull out the crown to the first click.2. Set the day by rotating the crown.3. Push the crown back in to the normalposition.Avoid setting the day between 9:00p.m. and 1:00 a.m. (the day displaymay not change in the following day).For a watch with an elapsed time bezelRotate the elapsed time bezel to align the mark with theminute hand.After certain amount of time elapsed, read the graduation onthe elapsed time bezel which the minute hand points to.The elapsed time is indicated.Some water resistant models are equipped with a screw lockcrown.With such models, you must unscrew the crown in thedirection noted in the illustration to loosen it before you canpull it out. Do not pull too forcibly on such crowns.Also note that such watches are not water resistant whiletheir crowns are loosened. Be sure to screw the crownsback in as far as they will go after making any setting.

    Use
    Do not use this watch for scuba diving or other types of diving that requires air tanks.
    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.) are being used. Such conditions can reduce water
    resistance.
    After submersion in seawater, use plain water to rinse all salt and dirt from the watch.
    In order to maintain water resistance, have the gaskets of your watch replace periodically
    (about once every two or three years).
    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.
    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.
    Continued use of the watch with water inside can result in damage to electronic and
    mechanical components, the face of the watch, etc.
    Band
    Tightening the band too tightly can cause you to sweat and make it hard for air to pass
    under the band, which can lead to skin irritation. Do not fasten the band too tightly. There
    should be enough room between the band and your wrist so you can insert your finger.
    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.
    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.
    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.).
    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. Very strong electrostatic charge even can damage electronic components.
    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.
    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.
    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.
    Failure to clean dirt from the watch for long periods can cause fluorescent color to fade.
    Wash dirt off with water as soon as possible and then dry the watch.
    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.
    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.
    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.
    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.
    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. Use an absorbent soft cloth
    to wipe the band clean of dirt, sweat, and moisture. The bacteria and odor resistant band
    suppresses the formation of organisms and bacteria. It does not protect against rash due
    to allergic reaction, etc.
    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.
    Keep a leather band clean by wiping it with a dry cloth. Both resin bands and leather
    band can become worn and cracked over time when subjected to normal daily use.
    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.
    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. 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.
    Even if the surface of the metal appears clean, sweat and rust in crevasses can soil the
    sleeves of clothing, cause skin irritation, and even interfere with watch performance.
    Premature Wear
    Leaving sweat or water on a resin band or storing it an area subject to high moisture can
    lead to premature wear, cuts, and breaks.
    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 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.
    Initial Battery
    The battery that comes loaded in your watch when you purchase it is used for function
    and performance testing at the factory.
    This type of test battery may go dead quicker than the normally rated battery life as noted
    in the User’s Guide. Note that you will be charged for replacement of this battery, even if
    replacement is required within the watch’s warranty period.
    Low Battery Power
    Low battery power is indicated by large timekeeping error, when display contents are
    dim, or when the display does blank.
    Operation while battery power is low can result in malfunction. Replace the battery as
    soon as possible.
