4. Setup Instructions

4.1 SIM Card Preparation

1. Acquire a Micro SIM Card: The TK816 requires a micro SIM card. It is recommended to use a SIM card with a data plan for continuous real-time tracking. A prepaid SIM card is suitable for occasional SMS/call-based location queries.
2. Disable SIM PIN: Insert the new SIM card into a smartphone. Access the phone's settings to disable the PIN request for the SIM card. This is crucial for the tracker to function correctly.
3. Test SIM Card: Make a brief call or send an SMS from the smartphone using the SIM card to ensure it is active and working.
4. Insert SIM Card into Tracker: Carefully insert the prepared micro SIM card into the SIM card slot on the TK816 tracker. Ensure it is inserted in the correct orientation.

4.2 Device Installation

1. Locate OBD Port: Identify the OBD-II port in your vehicle. This is typically located under the dashboard on the driver's side.
2. Connect Tracker: Plug the TKSTAR TK816 directly into the vehicle's OBD-II port. No tools are required for this step.
3. Initial Activation: Ensure the vehicle is in an open-sky area to allow the GPS signal to be acquired. Wait 1-2 minutes for the device to initialize and acquire a GPS signal. The indicator lights on the device will confirm its status.

5. Operating Instructions

5.1 Real-time Tracking

5.2 Geo-fencing

Geo-fencing allows you to set a virtual boundary for your vehicle. If the tracker enters or exits this predefined area, it will send an alert message to the authorized phone number.

• Setting up Geo-fence: Use the WINNES GPS App or web platform to define a geo-fence area on the map.
• Receiving Alerts: When the vehicle crosses the geo-fence boundary, an alert will be sent to the designated contact number.
