First, Familiarize Yourself with This Information

Battery

The battery installed at the factory is discharged during storage and transit. Replace the battery when it shows the first signs of discharge (dim indicator) at your CASIO dealer or distributor.

Water Resistance

These watches are water-resistant to withstand static pressure indicated on the case back (50, 100, or 200 meters) and saltwater. However, dynamic pressure generated by moving underwater is greater than static pressure. Please refer to the following table:

Notes:

• These watches are not water-resistant; avoid exposing them to any moisture.
• Do not pull out the crown when the watch is wet.
• Do not press buttons or pull out the crown underwater.
• You can press buttons underwater, but do not press recessed buttons or pull out the crown. If saltwater gets on the watch, rinse it thoroughly with fresh water and wipe it dry.
• Can be used for diving (except for depths requiring a helium-oxygen gas mixture).
• Do not pull out the crown underwater.
• Some water-resistant watches are equipped with leather bands. Do not wear such models while swimming or in any other situation involving immersion in water.

Precautions for Operating Your Watch

• Do not attempt to open the case or remove the back cover.
• The water and dust-proof packing needs to be replaced every 2-3 years.
• If water or condensation gets inside the watch, have it repaired immediately by your CASIO dealer or distributor.
• Do not expose the watch to excessively high temperatures.

GENERAL INSTRUCTIONS

• Although the watch is equipped with an shock-resistant mechanism, avoid subjecting it to strong impacts or dropping it on hard surfaces.
• Do not overtighten the bracelet. A finger should be able to fit under the bracelet.
• Clean the watch and bracelet with a soft, dry cloth or one dampened with a mild soap solution. Do not use volatile chemical solvents (such as benzine, solvents, aerosol cleaners, etc.).
• Always store the watch in a dry place when not in use.
• Do not expose the watch to aggressive chemicals such as benzine, cleaning agents, aerosols. Chemical reactions with such agents can damage the gasket, case, and polish.
• Some watch bracelets have their specifications printed on them. Exercise caution when cleaning such bracelets to avoid erasing them.
• For watches equipped with plastic bracelets...
  • You may notice a white powdery residue on the bracelet. This substance is not harmful to your skin or clothing and can be removed by wiping the bracelet with a cloth.
  • If moisture is left on a plastic bracelet, or if such watches are kept in a humid environment, the bracelet may warp, crack, or tear. To preserve the plastic bracelet, wipe off dirt or moisture with a soft cloth as soon as possible.
• For watches with fluorescent bracelets and cases...
  • Prolonged exposure to direct sunlight can cause the fluorescence color to fade.
  • Prolonged contact with moisture can cause the fluorescence color to fade. Wipe moisture from the surface as soon as possible.
  • Prolonged contact with other wet surfaces can cause the fluorescence color to fade. Wipe moisture from the fluorescent surface as soon as possible and stop the unwanted contact with other surfaces.
  • Strong friction of a surface with a printed fluorescent pattern against another surface can cause the printed color to transfer to the other surface.
• CASIO COMPUTER CO., LTD is not responsible for claims from third parties that may arise from the use of these watches.

If you press the 'C' button when the second value is between 30 and 50, 1 minute is added to the minute value when resetting to "00". If the second value is between 00 and 29, the minute value remains unchanged.
4. When other digits (except seconds) are flashing, press the 'C' button to increase their numerical value or the 'B' button to decrease it. Holding the buttons down allows for rapid changes.
5. To switch between 12- and 24-hour format, press the 'L' button while any digit is flashing.
6. When 12-hour format is selected, the 12H indicator appears in the text area. When using 12-hour format, the 'P' indicator appears on the screen, indicating PM. There is no indicator for AM. When 24-hour format is selected, the 24H indicator appears in the text area and on the screen.

AUTO-LIGHT FUNCTION

When the auto-light function is enabled, the watch illuminates automatically for a few seconds each time your hand is positioned as shown in the figure below. The watch is not designed to be worn on the inside of the wrist, as accidental activation of the auto-light may occur when not needed, shortening battery life. Hold your hand parallel to the ground, and turn the watch towards you by approximately 40 degrees to activate the backlight. * The backlight may not illuminate if the watch face is tilted more than 15 degrees from parallel to the left or right. Ensure your hand is parallel to the ground.

* Static electricity or magnetic forces can interfere with the proper operation of the auto-light. If the auto-light does not activate, try returning the watch to its original position (parallel to the ground) and turn it towards you again. If this does not help, shake your hand downwards vigorously and try turning the watch again to activate the backlight. * It is possible for the backlight activation to be delayed by up to 1 second after turning your hand. This is not an indication of malfunction.

Turning Auto-Light On and Off

In Current Time Mode, press and hold the 'C' button for one or two seconds to turn the auto-light function on or off.

* The auto-light indicator appears on the display in all modes when the auto-light function is enabled. * To protect the battery from rapid depletion, the auto-light function automatically turns off for approximately 2 hours after use. If you wish to use the backlight again, repeat the activation procedure. * In any mode, press the 'L' button to illuminate the display for 2 seconds, regardless of whether auto-light is enabled.

Warning!

• Never attempt to use the watch at high altitudes, in dark excursions, or when in unstable positions. This is risky and may lead to an accident.
• Never attempt to use your watch while running along the side of a road or in other places where there may be automotive or pedestrian traffic. This is risky and may lead to an accident.
• Never attempt to use the watch while riding a bicycle, motorcycle, or other similar motorized transport. This is risky and may lead to a traffic accident or personal injury.
• When wearing the watch, always ensure the auto-light is turned off before riding a bicycle, motorcycle, or other motorized transport. Sudden, unintentional activation of the auto-light may distract you, which could lead to an accident.
