• The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is applied in all other modes.

Stopwatch

You can use the stopwatch to measure elapsed time, lap times and split times. If you specify a distance value, the stopwatch also will calculate and display speeds.

• The digital display range of the stopwatch is 99 hours, 59 minutes, 59.999 seconds. The stopwatch continues to run until you stop it. If it reaches the above limit, it will restart the time measurement from zero.
• The stopwatch operation continues even if you exit the Stopwatch Mode. If you exit the Stopwatch Mode while a stopwatch operation is in progress, the upper digital segments will appear and disappear sequentially in accordance with the passage of timekeeping seconds. This is to let you know that a stopwatch operation is in progress.
• All of the operations in this section are performed in the Stopwatch Mode, which you enter by pressing C (page E-7).

Important!

• Check to make sure that the speed hand is not moving before you perform any Stopwatch Mode button operation. Specifying a Distance Value You can use the procedure below to specify a distance value, if you want. If you specify a distance value, the watch will calculate and indicate speed for certain stopwatch operations.
• The distance value represents kilometers, miles, or any other distance unit you want. Specifying a distance value of 10.0, for example, can mean 10.0 kilometers or 10.0 miles.
• No speed calculation is performed when 0.0 is specified as the current distance value.
• For lap time readings, you can specify either the lap distance (when all the laps are the same distance) or the total race distance.
• For split time readings, you can specify the total race distance only. Though the watch will indicate a speed each time you take a split reading, they will be based on the total race distance, and so they will not indicate actual intermediate split speeds.

To specify a distance value

1. In the Stopwatch Mode, make sure the stopwatch is stopped and reset to all zeros.
   • If you need to reset the stopwatch to all zeros, press A.
2. Hold down A for at least three seconds until the current distance value setting flashes in the upper digital display.
   • This is the distance value setting mode.
3. Press C to move the flashing between the values on the left side and right side of the distance value decimal point.
4. While a distance value is flashing, use D (+) and B (–) to change it.
   • You can specify a distance value in the range of 0.1 to 99.9.
5. After specifying the distance value you want, press A to exit the setting mode.

How speed is indicated

• While an elapsed time measurement operation is being performed in the Stopwatch Mode, the watch will indicate a speed value, which is calculated based on the distance you specified and the elapsed time. The speed value is indicated as described below.
• Upper digital segments: 100 unit
• 1000 appears when the speed exceeds 1,000.
• MACH appears when the speed exceeds 1,226.
• The speed hand indicates speed values less than 100. Only even-numbered values are indicated.
• Speed can be indicated from 0 to 1998. OVER is indicated by the speed hand when the speed exceeds 1998.

Example:

• When the speed value is 1,740.
• Speed hand: Indicates 40.
• Upper digital segments: Indicate 700.
• 1000 and MACH indicators: Displayed

Reference

This section contains more detailed and technical information about watch operation. It also contains important precautions and notes about the various features and functions of this watch.

Auto Return Features

• If you leave the watch with a flashing setting on any digital display for two or three minutes without performing any operation, the watch will exit the setting mode automatically.
• The watch will return to the Timekeeping Mode automatically if you do not perform any operation for two or three minutes in the Alarm Mode.

High-Speed Movement

• The D and B buttons are used to change setting in various setting modes. In most cases, holding down these buttons will start high-speed movement.

Initial Screens
When you enter the Stopwatch Mode, 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.
• 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 when battery has replaced.
• The current time for all city codes in the Timekeeping Mode and World Time Mode is calculated in accordance with the Coordinated Universal Time (UTC) for each city, based on your Home City time setting.

Illumination Precautions

• Illumination may be difficult 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

• 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. If you want to wear the watch on the inside of your wrist, turn off the auto light switch feature.
• Illumination may not turn on if the face of the watch is more than 15 degrees above or below parallel. Make sure that the back of your hand is parallel to the ground.
• Illumination turns off in about 1.5 seconds or 3 seconds, even if you keep the watch pointed towards your face.
• 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. This does not necessarily indicate malfunction of the auto light switch.
• You may notice a very faint clicking sound coming from the watch when it is shaken back and forth. This sound is caused by mechanical operation of the auto light  switch, and does not indicate a problem with the watch.

Operating Precautions

Water Resistance

• The information below applies to watches with WATER RESIST or WATER RESISTANT marked on the back cover.
  

  		Water Resistance Under Daily Use	Enhanced Water Resistance Under Daily Use
  			5 Atmospheres	10 Atmospheres	20 Atmospheres
  Marking	On watch front or on back cover	No BAR mark	5BAR	10BAR	20BAR
  Example of Daily Use	Hand washing, rain	Yes	Yes	Yes	Yes
  	Water-related work, swimming	No	Yes	Yes	Yes
  	Windsurfing	No	No	Yes	Yes
  	Skin diving	No	No	Yes	Yes

• Do not use your 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, note the usage precautions described below. Such types of use reduce water resistance performance and can cause fogging of the glass.
  • Do not operate the crown or buttons while your watch is submersed in water or wet.
  • Avoid wearing your watch while in the bath.
  • Do not wear your watch while in a heated swimming pool, sauna, or any other high temperature/high humidity environment.
  • Do not wear your watch while washing your hands or face, while doing housework, or while performing any other task that involves soaps or detergents.
• After submersion in seawater, use plain water to rinse all salt and dirt from your watch.
• To maintain water resistance, have the gaskets of your watch replaced periodically (about once every two or three years).
• A trained technician will inspect 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. Sudden and extreme temperature changes (such as coming into an air conditioned room in the summer and standing close to an air conditioner outlet, or leaving a heated room in the winter and allowing your watch to come into contact with snow) can cause it to take longer for glass fogging to clear up. If glass fogging does not clear up or if you notice moisture inside of the glass, immediately stop using your watch and take it to your original retailer or to an authorized CASIO service center.
• Your water-resistant watch has been tested in accordance with International Organization for Standardization regulations.

Band

• Tightening the band too tightly can cause you to sweat and make it difficult 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, and other conditions can cause the band to break or come off of your watch, which in turn can cause band pins to fly out of position or to fall out. This creates the risk of your watch falling from your wrist and becoming lost, and also creates the risk of personal injury. Always take good care of your band and keep it clean.
• Immediately stop using a band if you even notice any of the following: loss of band flexibility, band cracks, band discoloration, band looseness, band connecting pin flying or falling out, or any other abnormality. Take your watch to your original retailer or to a CASIO service center for inspection and repair (for which you will be charged) or to have the band replaced (for which you will be charged).

Temperature

• Never leave your 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 your watch where it will be exposed to very low temperatures. Temperature extremes can cause your watch to lose or gain time, to stop, or otherwise malfunction.
• Leaving your watch in an area hotter than +60°C (140°F) for long periods can lead to problems with its LCD. The LCD may become difficult to read at temperatures lower than 0°C (32°F) and greater than +40°C (104°F).
  Impact
• Your watch is designed to withstand impact incurred during normal daily use and during light activity such as playing catch, tennis, etc. Dropping your 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 engaging in strenuous sports activities (motocross, etc.)

Magnetism

• Though this watch is designed to maintain normal performance in DC magnetic fields up to 4800 A/m, it should not be allowed to come into contact with or be located close to a source of strong magnetism (audio speakers, magnetic necklace, cell phone, etc.) Sources of strong magnetism can affect the motor that moves the hands of the watch, causing them to slow down, speed up, or stop, resulting in the incorrect time being displayed.
• Very strong magnetism (from medical equipment, etc.) should be avoided because it can cause malfunction of your watch and damage to electronic components. Electrostatic Charge
• Exposure to very strong electrostatic charge can cause your watch to display the wrong time. Very strong electrostatic charge even can damage electronic components.
• Electrostatic charge can cause the display to go blank momentarily or cause a rainbow effect on the display.

Chemicals
Do not allow your 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 resin case, resin band, leather, and other parts.

Storage
If you do not plan to use your watch for a long time, thoroughly wipe it free of all dirt, sweat, and moisture, and store it in a cool, dry place.

Resin Components

• Allowing your watch to remain in contact with other items or storing it together with other items for long periods while it is wet can cause color on resin components to transfer to the other items, or the color of the other items to transfer to the resin components of your watch. Be sure to dry off your watch thoroughly before storing it and make sure it is not in contact with other items.
• Leaving your watch where it is exposed to direct sunlight (ultraviolet rays) for long periods or failure to clean dirt from your watch for long periods can cause it to become discolored.
• Friction caused by certain conditions (strong 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.
• Leaving your watch wet for long periods can cause fluorescent color to fade. Wipe the watch dry as soon as possible after it becomes wet.
• Semi-transparent resin parts can become discolored due to sweat and dirt, and if exposed to high temperatures and humidity for long periods.
• Daily use and long-term storage of your watch can lead to deterioration, breaking, or bending of resin components. The extent of such damage depends on usage conditions and storage conditions.

Leather Band

• Allowing your 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 leather band to transfer to the other items or the color of the other items to transfer to the leather band. Be sure to dry off your watch thoroughly with a soft cloth 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.
  CAUTION: Exposing a leather band to rubbing or dirt can cause color transfer and discoloration.

Metal Components

• Failure to clean dirt from metal components can lead to formation of rust, even if components are stainless steel or plated. If metal components exposed to sweat or water, wipe thoroughly with a soft, absorbent cloth and then place the watch in a well-ventilated location to dry.
• Use a soft toothbrush or similar tool to scrub the metal with a weak solution of water and a mild neutral detergent, or with soapy water. Next, rinse with water to remove all remaining detergent and then wipe dry with a soft absorbent cloth. When washing metal components, wrap the watch case with kitchen plastic wrap so it does not come into contact with the detergent or soap.

Bacteria and Odor Resistant Band

• The bacteria and odor resistant band protects against odor generated by the formation of bacteria from sweat, which ensures comfort and hygiene. In order to ensure maximum bacteria and odor resistance, keep the band clean. Use an absorbent soft cloth to thoroughly wipe the band clean of dirt, sweat, and moisture. A bacteria and odor resistant band suppresses the formation of organisms and bacteria. It does not protect against rash due to allergic reaction, etc.

Liquid Crystal 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 your watch or its malfunction.

User Maintenance

Caring for Your Watch
Remember that you wear your watch next to your skin, just like a piece of clothing. To ensure your watch performs at the level for which it is designed, keep it clean by frequently wiping with a soft cloth to keep your watch and band free of dirt, sweat, water and other foreign matter.

• Whenever your watch is exposed to sea water or mud, rinse it off with clean fresh water.
• For a metal band or a resin band with metal parts, use a soft toothbrush or similar tool to scrub the band with a weak solution of water and a mild neutral detergent, or with soapy water. Next, rinse with water to remove all remaining detergent and then wipe dry with a soft absorbent cloth. When washing the band, wrap the watch case with kitchen plastic wrap so it does not come into contact with the detergent or soap.
• For a resin band, wash with water and then wipe dry with a soft cloth. Note that sometimes a smudge like pattern may appear on the surface of a resin band. This will not have any effect on your skin or clothing. Wipe with a cloth to remove the smudge pattern.
• Clean water and sweat from a leather band by wiping with a soft cloth.
• Not operating a watch crown, buttons, or rotary bezel could lead to later problems with their operation. Periodically rotate the crown and rotary bezel, and press buttons to maintain proper operation.

Dangers of Poor Watch Care
Rust

• Though the metal steel used for your watch is highly rust-resistant, rust can form if your watch is not cleaned after it becomes dirty.
  • Dirt on your watch can make it impossible for oxygen to come into contact with the metal, which can lead to breakdown of the oxidization layer on the metal surface and the formation of rust.
• Rust can cause sharp areas on metal components and can cause band pins to fly out of position or to fall out. If you ever notice any abnormality immediately stop using your watch and take it to your original retailer or to an authorized CASIO service center.
• 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 bezel, or storing your watch 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. Should you ever experience a rash or other skin irritation, immediately remove your 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 in the User’s Guide. Use of a  different battery type can cause malfunction.
• When replacing the battery, also request a check for proper water resistance.
• Ornamental resin components may become worn, cracked, or bent over time when subjected to normal daily use. Note that if cracking or any other abnormality indicating possible damage is noticed in a watch submitted for battery replacement, your watch will be returned with an explanation of the abnormality, without the requested servicing being performed.

Initial Battery

• The battery that comes loaded in your watch when you purchase it is used for function and performance testing at the factory.
• The 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 your watch’s warranty period.

Low Battery Power

• Low battery power is indicated by large timekeeping error, by dim display contents, or by a blank display.
• Operation while battery power is low can result in malfunction. Replace the battery as soon as possible.
