4. Maintenance
4.1 Charging
Use the provided charging cable to charge the watch. Connect the magnetic end of the cable to the charging port on the back of the watch and the USB end to a compatible power adapter (not included). A full charge typically takes a few hours. The watch uses a Lithium Polymer battery.
4.2 Cleaning and Care
Wipe the watch regularly with a soft, dry cloth to remove dust and smudges. Avoid using harsh chemicals or abrasive materials. While the watch is designed for daily wear, it is not fully waterproof. Avoid prolonged exposure to water, such as swimming or showering, to prevent damage. Protect the watch from extreme temperatures and direct sunlight.
5. Troubleshooting
- "Device Offline" Message: This usually indicates no network coverage or the watch is off. Ensure the SIM card is correctly inserted, activated, and has sufficient balance/data. Move to an area with better cellular reception.
- Inaccurate GPS Location: While the watch uses multiple positioning methods, GPS accuracy can vary based on environmental factors (e.g., indoors, dense urban areas). Ensure the watch has a clear view of the sky for optimal GPS performance.
- Cannot Make/Receive Calls: Verify the SIM card is active and has calling capabilities. Check if the numbers are correctly saved in the watch's phonebook and if "Stranger Rejection" or "School Mode" settings are interfering.
- App Connection Issues: Ensure your smartphone has a stable internet connection. Re-bind the watch to the app if necessary. Check for app updates.
