Maintenance

- Charging: Use only the provided magnetic charging cable. Ensure the charging contacts are clean and dry before charging to prevent corrosion.
- Storage: Store the watch in a cool, dry place when not in use. Avoid extreme temperatures.
- Water Exposure: While IP68 rated, prolonged exposure to water or use in conditions beyond its rating (e.g., hot showers, saunas) can damage the device. Always dry the watch thoroughly after it gets wet.
Troubleshooting
- Watch not turning on: Ensure the watch is fully charged. Connect it to the charger for at least 30 minutes.

- Inaccurate health data: Ensure the watch is worn snugly on your wrist, not too tight or too loose. Clean the sensors regularly. Note that health data is for reference only and not for medical diagnosis.
- Notifications not appearing: Check app permissions on your phone to ensure KUMIFit has access to notifications. Verify that notifications are enabled within the KUMIFit app settings for specific applications.
