It is suitable for daily activities like hand washing and exposure to rain. However, it is NOT suitable for swimming, diving, hot showers, or activities involving high-speed water flow or submersion below diving depths. Damage caused by improper water exposure is not covered by warranty.

7. Troubleshooting

- Inaccurate GPS location: Ensure the watch has a clear view of the sky for GPS signals. Wi-Fi and LBS (Location Based Service) provide location indoors but may be less precise. Check app settings for location refresh rate.
