Maintenance
Water Resistance
Your Casio WS-1700H-1AVDF watch is water resistant up to 100 meters. This means it is suitable for swimming, snorkeling, and showering. 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.
Cleaning
Wipe the watch case and band with a soft, dry cloth. For resin bands, you can use a mild soap solution and rinse thoroughly with clean water, then dry completely. Avoid using harsh chemicals or abrasive cleaners.
Battery Replacement
The watch uses one Lithium Metal battery. When the display becomes dim or functions become erratic, it is time to replace the battery. Battery replacement should ideally be performed by a qualified watch technician to ensure proper sealing and water resistance. Attempting to replace the battery yourself may void the warranty and compromise water resistance.
Troubleshooting
| Problem | Solution |
|---|---|
| Display is blank or dim. | The battery may be low or depleted. Replace the battery. |
| Time is incorrect. | Adjust the time and date settings as described in the "Setting the Time and Date" section. |
| Buttons are unresponsive. | Ensure the watch is not in a locked mode (if applicable, though not a common feature for this model). If wet, dry the watch thoroughly before operating buttons. If the issue persists, a reset or service may be required. |
| Water appears inside the watch. | Immediately take the watch to a qualified service center. Water intrusion can cause severe damage. Avoid further exposure to water. |
