Casio LA-11 Watch User Manual

Battery

The battery installed at the factory may discharge during storage and in the store. When the battery indicator starts to dim, replace the battery at your CASIO dealer or distributor.

Water Resistance

Watches are classified by rating (from I to IV) according to their water resistance. Check your watch's rating using the table below for proper operation.

Notes:

• I: These watches are not waterproof; avoid moisture.
• III: Do not press buttons underwater.
• IV: Buttons can be pressed underwater, but do not press recessed buttons. If seawater gets on the watch, rinse it with fresh water and wipe dry.
• Some water-resistant watches come with leather straps. Do not wear such models while swimming or in any other situation involving immersion of the strap in water.

Precautions for Using Your Watch

• Do not attempt to open the case or remove the back cover.
• The water and dust-proof gasket needs to be replaced every 2-3 years.
• If water or condensation gets inside the watch, take it to your CASIO dealer or distributor for repair immediately.
• Do not expose the watch to excessively high temperatures.
• Although the watch has a shock-resistant mechanism, avoid strong impacts or dropping it on hard surfaces.
• Do not overtighten the bracelet. A finger should fit under the bracelet.
• To clean the watch and bracelet, use a soft cloth, dry or dampened with a mild soap solution. Do not use volatile chemical solvents (such as gasoline, solvents, cleaning aerosols, etc.).
• Always store the watch in a dry place when not in use.
• Do not expose the watch to aggressive chemicals such as gasoline, cleaning agents, aerosols. Chemical reactions with such agents can damage the gasket, case, and polish.
• Some watch bracelets have their specifications printed on them. Be careful not to rub them off when cleaning.

For Watches with Plastic Bracelets

You may notice a white powdery residue on the bracelet. This substance is harmless 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 sunlight may cause them to fade.
• Prolonged contact with moisture may cause the fluorescence color to fade. Wipe off moisture from the surface as soon as possible.
• Prolonged contact with other wet surfaces may cause the fluorescence color to fade. Wipe off moisture from the fluorescent surface as soon as possible and discontinue the unwanted contact.
• Strong friction of a fluorescent surface against another surface may cause the printed color to transfer.
