Maintenance

Regularly clean your watch and strap with a soft, dry cloth. If necessary, use a slightly damp cloth and mild soap, then rinse and dry thoroughly. Avoid harsh chemicals or abrasive materials.

Ensure the charging contacts on the watch and cable are clean and dry before charging. A full charge takes approximately 2 hours. The average battery life is 7 days with typical use, or 3-5 days with heavy use (e.g., frequent calls, continuous heart rate monitoring).
3. Storage
Store the watch in a cool, dry place away from direct sunlight and extreme temperatures when not in use for extended periods.
Troubleshooting
1. Watch Not Turning On
Ensure the watch is fully charged. If it still doesn't turn on, try long-pressing the function button.

If the watch fails to connect to the app:

- Restart both your phone and the watch.
- Check if the 'VeryFit' app has necessary permissions (location, Bluetooth).
- Try unbinding and re-pairing the device in the app.
3. Inaccurate Health Readings
For accurate readings, ensure the watch is worn snugly on your wrist, about one finger's width from your wrist bone. Avoid wearing it too loose or too tight. Keep the sensor clean.
4. Notifications Not Appearing
Verify that notification permissions are granted for the 'VeryFit' app and individual apps within your phone's settings. Also, check the notification settings within the 'VeryFit' app itself.
5. Factory Reset
If you encounter persistent issues, a factory reset can often resolve them. This option is usually found in the watch's settings menu or within the 'VeryFit' app under device management. Note: A factory reset will erase all data on the watch.
