Battery Life

The Casio WS-1700H-1AVCF is powered by a CR2025 battery, providing an approximate 10-year battery life. When the display becomes dim or functions become erratic, it may be time for a battery replacement. It is recommended to have battery replacement performed by an authorized Casio service center to ensure water resistance is maintained.

Cleaning

Wipe the watch regularly with a soft, dry cloth. For stubborn dirt, use a soft cloth dampened with water and mild soap, then wipe dry. Avoid using chemical cleaners or solvents, as they can damage the watch's resin components.

Troubleshooting

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

• Display is blank or dim: The battery may be low. Replace the battery.
• Incorrect time/date: Re-adjust the time and date settings as described in the "Setup" section. Ensure the correct city code and DST setting are selected.
• Tide/Moon data is inaccurate: Verify that the longitude and lunitidal interval settings are correct for your location. These values are crucial for accurate calculations.
• Buttons are unresponsive: Ensure the watch is not wet or submerged when attempting to operate buttons. If the issue persists, a reset may be required (refer to Casio support for specific reset procedures for your model).
• Watch is not water resistant after battery change: Always ensure that the gasket is properly seated and the case back is securely tightened after any opening of the watch. It is highly recommended to have water resistance testing performed by a professional after battery replacement.
