6. Operating Instructions
6.1 Power On/Off
- **Power On**: Press and hold the power button until the indicator lights turn on.
- **Power Off**: Press and hold the power button until the indicator lights turn off.
6.2 Tracking via Web Platform
Access the web-based tracking platform for real-time monitoring and management:

6.4 GPS+LBS Dual Positioning
The tracker uses both GPS (Global Positioning System) and LBS (Location Based Service) for accurate positioning:
- **GPS**: Provides high accuracy (5-10 meters) when a clear satellite signal is available, typically outdoors.
- **LBS**: Used when GPS signals are weak or unavailable (e.g., indoors, underground parking). LBS accuracy ranges from 100-2000 meters.
6.5 History Route Playback
The tracking platform and mobile app store historical location data for up to 6 months. You can review past routes at any time to see where the device has been.
6.6 Geo-fence Setup
A geo-fence allows you to define a virtual boundary. If the tracker enters or exits this predefined area, an alarm message will be sent to the authorized numbers and appear on the app/web platform.
6.7 Alarm Functions
The device supports several alarm types to enhance security:
- **Fall-off Alarm**: Automatically enabled. Alerts if the device is removed or dropped.

- **Storage Box**: Inside a metallic storage box or compartment.
- **Pedal Area**: Near metallic components in the pedal area.
- **Seat Frame**: Underneath the seat, attached to the metal frame.
- **Bumpers**: Inside or behind metallic bumper structures.
- **Other Assets**: Suitable for trucks, buses, motorcycles, bikes, beehives, safety boxes, and containers.
8. Maintenance
8.1 Waterproofing
The device has an IP65 waterproof rating, meaning it is protected against dust ingress and low-pressure water jets from any direction. While it can withstand splashes and rain, it is not designed for submersion in water. Ensure all covers, especially the SIM card slot, are securely closed to maintain waterproofing.
8.2 Battery Care
- Charge the device fully before extended periods of non-use.
- Avoid exposing the device to extreme temperatures (below -40°C or above +85°C) as this can degrade battery performance.
- Regular charging helps maintain battery health, especially for devices with long standby times.
9. Troubleshooting
- **Device not powering on**: Ensure the battery is charged. Connect to the charger and check if the charging indicator lights up.
- **No GPS signal**: Move the device to an open area with a clear view of the sky. GPS signals can be blocked by buildings, tunnels, or dense foliage.
- **Inaccurate location (LBS mode)**: If the device is indoors or in an area with poor GPS signal, it will switch to LBS positioning, which is less accurate. This is normal operation.
- **Cannot connect to network**: Check if the SIM card is correctly inserted and activated. Ensure the SIM card has sufficient balance or data plan. Verify that the SIM card's network bands are compatible with your device's regional version.
- **Alarms not working**: Check alarm settings in the mobile app or web platform. Ensure the device has a stable network connection to send alerts.
- **Login issues on platform/app**: Double-check the device ID and password. The default password is `123456`.
10. User Tips
- **Easy Installation**: The powerful magnet makes installation straightforward. Simply attach it to any suitable metallic surface on your vehicle or asset.
- **Wide Compatibility**: This tracker is versatile and can be used with cars, trucks, motorcycles, bikes, boats, and even for tracking beehives or safety boxes.
- **Battery Life Management**: While the device offers long standby times (up to 30 or 90 days depending on model), actual battery life will vary based on tracking frequency and usage of alarm features. For continuous tracking, consider charging regularly.
- **Multi-Device Management**: If you own multiple TKSTAR GPS trackers, the seller can help create a single user account to monitor and manage all your devices simultaneously through the web platform or mobile app.
