Maintenance
Water Resistance:
Your Casio B650WD-1ACF watch is water-resistant to 50 meters (165 feet). This means it is suitable for everyday use and can withstand splashes, rain, and brief immersion in water, such as showering or swimming in shallow water. It is not suitable for diving or prolonged exposure to high water pressure.
- Do not operate buttons while the watch is wet or submerged.
- Avoid exposing the watch to hot water or steam, as this can compromise the water resistance seals.
Battery Replacement:
The watch uses 1 Lithium Metal battery (included). When the display becomes dim or functions become erratic, it may be time to replace the battery. Battery replacement should ideally be performed by a qualified watch technician to ensure the water resistance is maintained.
Cleaning:
To clean your watch, wipe it with a soft, dry cloth. For the stainless steel band, a slightly damp cloth can be used, followed by immediate drying. Avoid using harsh chemicals or abrasive materials, which can damage the watch's finish.
Troubleshooting
- Display is blank or dim: The battery may be low or depleted. Replace the battery.
- Time is incorrect: Re-set the time and date according to the 'Setting the Time and Date' section. Ensure the correct AM/PM setting is selected.
- Buttons are unresponsive: Ensure the watch is not in a locked mode (if applicable) or that it is not wet. If the issue persists, a battery replacement or professional inspection may be required.
