5. Maintenance
5.1 Water Resistance
The wonlex 4G Kids Smart Watch is IP67 waterproof. This means it is resistant to splashes and brief immersion in water. However, it is not recommended to wear the watch while swimming or showering. It is best to remove the watch when washing hands or engaging in other water-contact activities to prevent damage.
5.2 Cleaning
Wipe the watch regularly with a soft, dry cloth. For stubborn dirt, use a slightly damp cloth and then dry thoroughly. Avoid using harsh chemicals or abrasive materials.
6. Troubleshooting
6.1 Connectivity Issues
- No Signal/Network: Ensure the SIM card is correctly installed and activated. Check for good network reception in your area. If using your own SIM, ensure it is a T-Mobile 4G compatible card (Verizon is not supported).
- Data Not Syncing: After SIM activation, allow up to 24 hours for GPRS and data settings to fully sync. Ensure the watch is powered on and in an area with good signal.
6.2 GPS Location Inaccuracy
The watch uses Wi-Fi, GPS, and LBS for location tracking. For optimal accuracy, ensure the watch has a clear view of the sky for GPS signals and is within Wi-Fi range when available. LBS (Location Based Service) provides approximate location when GPS/Wi-Fi signals are weak.
