3. Operating Instructions
3.1 Real-time Tracking
The TK905 provides real-time location tracking with GPS and LBS dual-mode positioning. GPS accuracy is typically 5-10 meters, while LBS (Location Based Service) is used when GPS signals are weak or unavailable, with accuracy ranging from 100-1000 meters.
- Access the real-time tracking feature through the mobile app or web platform.
- The device's current location will be displayed on a map interface (e.g., Google Maps).
- Location updates are continuous, allowing for constant monitoring.

3.2 Historical Route Playback
Review past movements of the tracker for up to 6 months. This feature is useful for analyzing travel patterns or verifying routes.
- Navigate to the "History Route" or "Playback" section within the app or web platform.
- Select a date and time range to view the historical path.
- The route will be displayed on the map with timestamps.

3.3 Geo-fence Function
Set up virtual boundaries (geo-fences) on the map. You will receive an alert if the tracker enters or exits these predefined areas.
- In the app/web platform, find the "Geo-fence" or "Safety Zone" setting.
- Draw a circular or polygonal area on the map.
- Configure alerts for entry, exit, or both.

3.4 Alarm Functions
The TK905 is equipped with multiple alarm features to enhance security and monitoring. Alerts are typically sent as text messages to the administrator number configured in the device settings.
- Over-speed Alarm: Receive an alert if the tracker exceeds a preset speed limit.
- Shake Alarm: An alarm is triggered if the device detects significant vibration or movement, indicating potential tampering or unauthorized vehicle movement.
- Low Power Alarm: When the battery level drops below 10%, an alert is sent to remind you to recharge the device.
- Movement Alarm: Alerts for unauthorized movement or towing of the vehicle.

4. Installation and Mounting
The Winnes TK905 features a strong magnetic base, allowing for quick and secure installation without the need for professional tools or permanent fixtures. It can be attached to any iron surface on a vehicle.
- Identify a flat, metallic surface on the vehicle where the tracker can be securely attached. Common locations include under the chassis, inside the trunk, or on metal frames.
- Ensure the surface is clean and free of debris for optimal magnetic adhesion.
- Simply place the tracker onto the chosen metallic surface. The strong built-in magnets will hold it in place.
