Setup
1. SIM Card Installation
- Ensure the device is powered off.
- Carefully open the silicone plug covering the SIM card slot.
- Insert a 2G GSM SIM card (850/900/1800/1900 MHz) into the slot. The SIM card is not included and must be purchased separately. Note: 3G and 4G SIM cards are not supported.
- Close the silicone plug securely to maintain waterproofing.
2. Initial Charging
- Connect the provided USB cable to the tracker's USB port and a 5V-1A wall charger (input 110-220V).
- Charge the device fully before first use. The indicator light will show charging status.
3. Power On/Off
- To power on, press and hold the power button until the indicator lights activate.
- To power off, press and hold the power button until the indicator lights turn off.
4. APN Setup for Online Tracking
To enable online tracking via the web platform or mobile application, GPRS must be enabled on the SIM card and the Access Point Name (APN) must be configured. Refer to your SIM card provider for the correct APN settings. Instructions for setting the APN are typically found in the full user manual or provided by the TKSTAR support platform.
Operating Instructions
1. Real-time Tracking
- SMS Tracking: To get the device's location, call the SIM card number inserted in the tracker or send an SMS message to it. The device will reply with an SMS containing a Google Maps link showing its current position.
- Online Platform/App Tracking: After setting up the APN, log in to the TKSTAR web platform or mobile application using your device ID and password to view real-time location, historical routes, and manage settings.
2. Geo-fence Setting

This image depicts the Geo-fence feature, showing a map with a defined safe zone. The TKSTAR TK915 can alert the user if the tracked vehicle enters or exits this designated geographical area.
The Geo-fence feature allows you to define a virtual boundary. If the tracker moves into or out of this boundary, an alarm will be triggered. This setting is typically configured through the online tracking platform or mobile application.
3. Overspeed Alarm

This image illustrates the overspeed alarm function. A smartphone displays 'speed alarm' messages, indicating that the TKSTAR TK915 has detected the tracked vehicle exceeding a preset speed limit.
You can set a maximum speed limit for the tracker. If the device exceeds this speed, it will send an alarm notification (e.g., SMS or app notification) to the designated administrator number. This alarm typically functions only in continuous positioning mode.
4. Low Power Alarm
When the battery power of the TK915 drops below 20%, the device will send a low power alarm notification, reminding you to recharge the battery promptly.
5. Vibration Sensor Alarm
If the device detects significant vibration, indicating potential unauthorized movement of the vehicle or asset it is attached to, it will send an SMS alert to your phone.
6. Anti-removal Alarm

This image demonstrates the anti-removal alarm feature of the TKSTAR TK915. The tracker, shown magnetically attached underneath a car, will send an SMS alert if its induction sensor is uncovered, indicating unauthorized removal.
The TK915 is equipped with an induction sensor. If the device is removed from its magnetic attachment point, it will send an alert (e.g., "Loosing alarm") to the administrator number and any configured SOS numbers via SMS.
7. Historical Route Playback
Access the online tracking platform or mobile application to review the historical routes taken by the TK915 tracker over a specified period.
Maintenance
Charging
To ensure optimal performance and battery life, charge the TK915 using the provided USB cable and a compatible 5V-1A charger. Recharge the device when the low power alarm is triggered.
Cleaning
Wipe the device with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners. Ensure the silicone plug for the SIM card and USB port is always securely closed to maintain its waterproof integrity.

Troubleshooting
- Device not powering on: Ensure the battery is charged. Connect to a power source and try again.
- No GPS signal: Ensure the device is in an open area with a clear view of the sky. GPS signals can be obstructed by buildings, tunnels, or dense foliage.
- No SMS reply: Check if the SIM card has sufficient credit and is active. Verify that the SIM card is a 2G GSM card and correctly inserted.
- Online tracking not working: Confirm that GPRS is enabled on the SIM card and the APN settings are correctly configured. Check your internet connection.
- Battery life shorter than expected: Ensure the device is fully charged. Frequent tracking updates or poor network signal can consume more power.
