Setup
1. SIM Card Installation
- Ensure the tracker is powered off.
- Locate the SIM card slot on the device.
- Insert a 4G-compatible SIM card into the slot. The tracker supports Normal, Micro, and Nano SIM cards (use appropriate adapters if necessary). Ensure the SIM card has an active data plan and is not PIN-locked.
- Close the SIM card slot cover securely to maintain waterproofing.

2. Charging the Device
Before first use, fully charge the TK905B tracker. Connect the provided USB charging cable to the tracker and a standard USB power adapter (not included). The charging indicator light will show the charging status.
3. App Installation
The TKSTAR TK905B uses the Winnes GPS app for tracking and management. This app is free and compatible with both Android and iOS devices.
- Search for "Winnes GPS" in your device's app store (Google Play Store for Android, Apple App Store for iOS).
- Download and install the app.
- Follow the in-app instructions to register an account and add your device using its unique ID (usually found on the device or packaging).
4. Initial Power On
Press and hold the power button until the indicator lights illuminate. The device will attempt to connect to the 4G/2G network and acquire a GPS signal. This may take a few minutes.
Operating Instructions
1. Positioning Technology (GPS+LBS)
The TK905B utilizes both GPS (Global Positioning System) and LBS (Location Based Service) for accurate tracking. GPS provides precise outdoor positioning, while LBS offers location data in areas where GPS signals are weak or unavailable (e.g., indoors or dense urban environments). This dual system ensures continuous tracking capability.

2. Real-time Tracking
Once the device is powered on and connected to the network, you can view its real-time location through the Winnes GPS app or web platform. The app provides a map interface showing the current position of your tracker.
3. History Route Playback
The tracker records and stores historical route data. You can access and review past movements of the device through the Winnes GPS app or web platform. This feature allows you to see where the tracker has been over a specified period.

4. Magnetic Attachment
The TK905B features powerful built-in magnets, allowing for easy and secure attachment to any metallic surface, such as the underside of a vehicle. Ensure the surface is clean and dry for optimal adhesion.

5. Network Compatibility
This product is designed to work in all countries that support 4G and 2G networks, ensuring broad compatibility for global use.
Maintenance
- Cleaning: Wipe the device with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners.
- Charging: Recharge the device regularly, especially if it's used for extended periods. A full charge ensures maximum battery life and continuous tracking.
- Storage: When not in use for a long time, store the device in a cool, dry place. It's recommended to charge it to about 50% before storage and recharge every few months to prevent battery degradation.
- Water Resistance: While the device is waterproof, avoid submerging it in water for extended periods or exposing it to high-pressure water jets. Ensure all ports are securely closed.
Troubleshooting
- Device not powering on: Ensure the device is fully charged. If it still doesn't power on, try a different charging cable or adapter.
- No GPS signal: Move the device to an open area with a clear view of the sky. GPS signals can be obstructed by buildings, tunnels, or dense foliage.
- No network connection: Check if the SIM card is correctly inserted and has an active data plan. Verify that the area has 4G/2G network coverage. Restart the device.
- Inaccurate location: In areas with poor GPS signal, the device may rely on LBS, which is less accurate. Ensure the device has a clear line of sight to the sky for optimal GPS performance.
- App not showing device: Double-check that the device ID entered in the app is correct. Ensure the device is powered on and has network connectivity.
User Tips
- For optimal battery life, consider setting the tracker to a less frequent reporting interval if continuous real-time updates are not critical.
- Regularly check the device's battery level through the app to avoid unexpected power loss.
- When attaching to a vehicle, choose a discreet location that does not interfere with vehicle operation or safety systems.
- Familiarize yourself with all features of the Winnes GPS app, such as geofencing and alert settings, to maximize the utility of your tracker.
