Setup Instructions
1. SIM Card Requirements
The TK905 requires a 2G GSM SIM card to function. Please ensure the SIM card supports 2G network connectivity in your region. A micro-SIM card is typically used. Ensure the SIM card has an active data plan and sufficient balance for SMS and data services.
2. SIM Card Insertion
- Open the rubber cover on the side of the device to access the SIM card slot.
- Insert the 2G GSM SIM card into the slot with the metal contacts facing down and the cut corner oriented correctly.
- Ensure the SIM card is fully seated.
- Close the rubber cover firmly to maintain water resistance.
3. Initial Activation and Location Check
After inserting the SIM card, power on the device. To perform an initial check:
- Use your mobile phone to call the phone number of the SIM card inserted in the tracker.
- The tracker should respond with an SMS message containing a Google Maps link to its current location.
- If you do not receive a Google link, contact your SIM card operator to reset the network or check the SIM card status.
4. APN Configuration for App Tracking
If the mobile application cannot track the device in real-time, you may need to configure the Access Point Name (APN) settings. This is done by sending specific SMS commands to the tracker's SIM card number. The APN settings vary by SIM card provider.
Please contact TKSTAR customer support or refer to the detailed instructions provided with your SIM card for the correct APN settings and SMS commands. Typically, this involves sending 3 SMS messages.

Operating Instructions
1. Real-time Tracking
The TK905 allows for real-time tracking via a dedicated mobile application or a web-based platform. Once the APN is configured, you can log in to view the device's current location on a map.
- Download the official TKSTAR tracking app from your smartphone's app store or visit the designated web tracking platform.
- Log in using your device ID and password (usually found on the device or packaging).
- The map will display the tracker's current position, with updates typically every 10 seconds.


2. Historical Route Playback
You can review the historical movement of the tracker for up to 6 months. This feature is accessible through both the mobile application and the web platform.
- Navigate to the "History Route" or "Historical Data" section within the app or web platform.
- Select the desired date range to view the travel path.
- The route will be displayed on the map, showing the path taken by the device.

3. Geo-fence Alarm
Set up virtual boundaries (geo-fences) on the map. When the tracker enters or exits these predefined zones, you will receive an alarm notification.
- Access the "Geo-fence" setting in the app or web platform.
- Draw a polygon or circle on the map to define your desired safety zone.
- Configure the alarm type (entry, exit, or both).
4. Overspeed Alarm
Receive an alarm message on your phone if the tracked vehicle exceeds a speed limit you have set.
- Go to the "Overspeed Alarm" settings in the application.
- Set the maximum allowed speed.
- An alert will be sent if this speed is surpassed.
5. Low Battery Alarm
The device will send an SMS notification to the master contact number when its battery level drops below 10%, reminding you to recharge.
6. Vibration Alarm
This alarm is primarily used for anti-theft purposes. If the device detects unexpected vibration or movement, it will send an alarm message.
- Activate the "Vibration Alarm" feature in the app settings.
- Upon receiving a vibration alarm, check the vehicle's status promptly.
