Maintenance
Water Resistance (IP68)
The RUXINGX T40 Smartwatch is IP68 waterproof, meaning it is resistant to dust and can withstand immersion in water up to 1.5 meters for up to 30 minutes. It is suitable for daily activities like hand washing and playing with water.
Important: Do not use the watch in hot water, steam, or humid environments (e.g., hot showers, saunas). Prolonged exposure to high temperatures or steam can compromise the waterproof seals.

Figure 9: The IP68 waterproof rating allows for daily water exposure (see bottom-left panel).
Cleaning and Care
- Clean the watch regularly with a soft, dry cloth.
- Avoid using harsh chemicals or abrasive materials.
- Ensure the charging contacts are clean and dry before charging.
Troubleshooting
| Issue | Possible Cause / Solution |
|---|---|
| Inaccurate GPS Location | GPS accuracy can be affected by environmental factors (e.g., indoors, dense buildings, bad weather). LBS (cellular tower positioning) is used when GPS signal is weak, which is less precise. Ensure the watch has a clear view of the sky for best GPS performance. |
| No Network Signal / Cannot Make Calls |
|
| App "SeTracker2" Issues (e.g., ads, poor translation) | The app's functionality and translation quality are managed by the app developer. Ensure you have the latest version of the app. For translation issues, the app often defaults to the phone's system language; changing your phone's language might affect the app's language. |
| Video Calls Not Working Properly | Video calls require a stable 4G network connection on both the watch and the connected smartphone. Check network signal strength. Video quality may vary based on network conditions. |
| No Vibration / Volume Issues | This model may not feature vibration. The ringtone volume might be linked to other system sounds (e.g., game sounds). Adjust the overall volume settings on the watch. |
