Troubleshooting
If you encounter issues with your Casio WS-B1000 watch, refer to the following common solutions:
- Watch time is incorrect: Ensure your watch is paired with the CASIO WATCHES app and Bluetooth is enabled on your phone. The watch should automatically synchronize time. If not, manually initiate a connection from the app or watch.

- Step tracker accuracy issues: Verify that your personal data (height, weight) is accurately entered in the CASIO WATCHES app. Ensure the watch is worn securely on your wrist.
- Display is dim or blank: The battery may be low. Consider replacing the battery at an authorized service center.
