CASIO BG-1000 Digital Watch User Manual

Battery ?

The battery installed at the factory may discharge during storage and in the store. If you notice signs of battery depletion (dim indicator), replace the battery at your CASIO dealer or distributor.

Water Resistance ?

These watches can withstand water penetration under static pressure indicated on the case back (50, 100, or 200 meters), as well as seawater at the indicated depth. However, dynamic pressure generated during underwater activities is greater than static pressure. Refer to the table below for details.

Notes:

• I: These watches are not waterproof; avoid any moisture ingress.
• II: Do not pull out the crown [⚙️] while the watch is wet.
• III: Do not press buttons [C], [B], [D] or pull out the crown [⚙️] underwater.
• IV: Buttons [C], [B], [D] can be pressed underwater, but do not press recessed buttons or pull out the crown [⚙️]. If seawater gets on the watch, rinse it with fresh water and dry thoroughly.
• V: Can be used for diving (excluding depths requiring helium-oxygen gas mixtures).
• Do not pull out the crown [⚙️] underwater.
• 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 Watch Operation ⚠️

• Do not attempt to open the case or remove the back cover.
• The water and dust-proof gasket should be replaced every 2-3 years.
• If water or condensation gets inside the watch, take it to your CASIO dealer or distributor immediately for repair.
• 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 strap. A finger should fit underneath it.
• To clean the watch and strap, use a soft cloth, dry or dampened with a soapy 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.

General Instructions

• Do not expose the watch to aggressive chemicals such as gasoline, cleaning agents, aerosols. Chemical reactions with such agents can cause damage to the gasket, case, and polish.
• Some watch bands have their characteristics printed on them. Be careful not to erase them when cleaning such bands.
• For watches with plastic bands:
• You may notice a whitish powdery residue on the band. This substance is harmless to your skin or clothing and can be removed by wiping the band with a cloth.
• If moisture is left on a plastic band, or if the watch is kept in a humid environment, the band may warp, crack, or break. To preserve the plastic band, wipe off dirt or moisture with a soft cloth as soon as possible.
• For watches with fluorescent bands 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 off moisture from the surface as soon as possible.
• Prolonged contact with other moist surfaces can cause the fluorescence color to fade. Wipe off moisture from the fluorescent surface as soon as possible and avoid further contact.
• Strong friction of a surface with a fluorescent print against another surface can cause the print to transfer to the other surface.
