7. Maintenance
- Cleaning: Regularly wipe the watch screen and body with a soft, dry cloth. For stubborn smudges, a slightly damp cloth can be used, followed by immediate drying.
- Charging: Always use the original magnetic charging cable. Ensure the charging points on the watch and cable are clean and dry before charging to prevent corrosion.
- Storage: When not in use for extended periods, store the watch in a cool, dry place away from direct sunlight and extreme temperatures.
- Avoid Chemicals: Do not expose the watch to strong chemicals, detergents, or solvents, as these can damage the materials and finish.
- Extreme Conditions: While the watch is military-grade and 5ATM waterproof, prolonged exposure to very hot water (e.g., hot showers, saunas) or high-pressure water jets should be avoided as it may affect the seals.
8. Troubleshooting
- Watch Not Turning On: Ensure the watch is fully charged. If it still doesn't turn on, try pressing and holding the power button for 10-15 seconds.
- Connectivity Issues: Make sure Bluetooth is enabled on your phone and the watch is within range. Try unpairing and re-pairing the device in the FitCloudPro app. Restarting both your phone and watch can also resolve connection problems.
- Inaccurate Health Data: Ensure the watch is worn snugly on your wrist, not too tight or too loose. Clean the sensors on the back of the watch regularly. For best results, remain still during measurements.
- Short Battery Life: Reduce screen brightness, disable unnecessary notifications, and limit continuous heart rate monitoring. Ensure the 'Always-On Display' is used judiciously if extended battery life is a priority.
- App Syncing Problems: Check your internet connection. Ensure the FitCloudPro app is updated to the latest version. Close and reopen the app, or restart your phone.
