Maintenance

Proper care will ensure the longevity and performance of your Casio W-800H-1AVCF watch:

• Water Resistance: This watch is water resistant to 100 meters (330 feet). It is suitable for swimming, snorkeling, and other water activities. However, avoid operating buttons underwater to prevent water ingress.
• Battery Life: The watch is powered by a CR2025 Lithium Metal battery, providing an impressive 10-year battery life. When the display dims or functions become erratic, it may be time for a battery replacement. It is recommended to have battery replacement performed by a qualified watch technician to ensure water resistance is maintained.
• Cleaning: Clean the watch case and band with a soft, dry cloth. For stubborn dirt, use a mild soap solution and rinse thoroughly with clean water, then dry completely. Avoid harsh chemicals or abrasive materials.
• Temperature Exposure: Avoid exposing the watch to extreme temperatures (hot or cold) for prolonged periods, as this can affect battery life and internal components.

Troubleshooting

If you encounter issues with your watch, try these common troubleshooting steps:

• Blank or Dim Display: This usually indicates a low battery. Replace the CR2025 battery.
• Incorrect Time/Date: Re-enter the time setting mode and adjust the values as described in the 'Setup' section. Ensure the 12/24-hour format is correctly set.
• Buttons Not Responding: Check if the watch is in a specific mode that locks button functions. If not, a reset might be necessary (refer to the full user manual for specific reset procedures, if available).
• Water Inside Display: If condensation or water appears inside the watch, stop using it immediately and take it to an authorized service center. This indicates a breach in water resistance.
