Maintenance

Battery Information

Image: A gold and black emblem indicating '10 Year Battery Life'.

This watch is equipped with a long-life battery, designed to last approximately 10 years under normal use. When the display becomes dim or the light function weakens, it indicates that the battery power is low. Battery replacement should be performed by a qualified watch technician to ensure water resistance is maintained.

Water Resistance

The watch is rated for 100-meter water resistance. This means it is suitable for swimming, showering, and snorkeling. However, it is not suitable for scuba diving. Do not operate buttons while the watch is wet or submerged in water, as this can compromise the water resistance.

Cleaning

Wipe the watch case and band with a soft, dry cloth to remove dirt and moisture. For resin bands, a mild soap solution and water can be used, followed by thorough rinsing and drying. Avoid using harsh chemicals or abrasive cleaners.

Troubleshooting

• Display is blank or dim: The battery may be low. Consider professional battery replacement.
• Time is incorrect: Re-adjust the time and date settings as described in the 'Setup' section. Ensure DST (Daylight Saving Time) is correctly set if applicable.
• Alarm not working: Check if the alarm is activated in Alarm Mode. Ensure the volume/vibration setting is enabled.
• Buttons are unresponsive: Ensure the watch is not wet. If the issue persists, a reset may be required (consult a service center), or there might be an internal malfunction.

If problems persist after attempting these solutions, please contact a Casio service center for assistance.
