5. Operating Instructions
5.1 Real-time Tracking
Once the device is set up and connected to the app, you can view its real-time location on the map. The tracker intelligently selects the best positioning method (GPS, WiFi, LBS, AGP) for accuracy and energy efficiency.
5.2 Electronic Fence (Geo-fencing)
Set up a safety zone (geo-fence) within the app. You will receive alerts on your phone when the tracker enters or exits this predefined area. This feature is useful for monitoring vehicles or ensuring individuals stay within safe boundaries.

5.3 Remote Recording & Voice-Activated Recording
The device supports remote recording via the app. It also features voice-activated recording, automatically starting to record when it detects speech. This function utilizes silicon mark noise reduction technology for high-definition audio.
5.4 SOS Emergency Help
In an emergency, press and hold the SOS button on the device for 3 seconds. The tracker will automatically call the pre-set emergency contact numbers to alert them of the situation.

5.5 Street View Navigation
The mobile application includes a built-in street view navigation function, allowing you to clearly see the surrounding environment of the device. This helps in quickly finding the tracker in unfamiliar locations.
5.6 Track History
Review the historical movement data of the tracker through the mobile application or computer terminal to see past routes and locations.
6. Maintenance
- Keep the device dry. Do not expose it to water or moisture, as it is not waterproof.
- Avoid extreme temperatures. The device is designed to operate between -20°C and 85°C.
- Clean the device with a soft, dry cloth. Do not use harsh chemicals or cleaning solvents.
- Ensure the charging port is free from dust and debris to maintain proper charging functionality.

- Ensure the device is in an open area with a clear view of the sky. Check if the SIM card has an active data plan and sufficient balance. Verify that the SIM card is correctly inserted.
- App not connecting to the device:
- Check your internet connection. Ensure the device is powered on and has a working SIM card. Verify that the device ID entered in the app is correct. Try restarting both the device and the app.
- Voice recording not working:
- Ensure a TF card is inserted if required for storage. Check app settings for recording activation. Ensure the device is in an environment where sound can be picked up clearly.

8. User Tips
- IMEI Number: For network compatibility and activation, ensure your SIM card and network provider support the device's IMEI number. If you encounter issues, you may need to provide the IMEI to your network provider for registration.
- SIM Card Compatibility: Always use a SIM card that supports 2G-4G networks and has an active data plan for optimal performance.
- App Notifications: Enable push notifications for the GPS365 app on your smartphone to receive timely alerts for electronic fence breaches or SOS calls.
- Battery Optimization: While the device intelligently selects positioning modes, frequent real-time tracking or continuous recording will consume more battery. Adjust settings in the app to balance tracking frequency with battery life.
