Before Using

1. Power On / Off

Open the SIM card room cover, slide the switch to the ON position. The tracker powers on, indicated by a flashing Green LED. A Green LED flash every 4 seconds signifies normal operation. Refer to the LED indicator details for specific status.

2. Install SIM Card (Micro SIM Card)

Use a 2G/3G/4G Micro SIM card. Open the SIM card room cover, slide the metal cover to 'OPEN', insert the SIM card correctly, then slide the cover to 'LOCK'.

Note: Ensure the SIM card has data service enabled. Some SIM cards require an SMS or USSD command to activate internet service. A data package of 20-30MB per month is recommended.

3. Installation

The tracker requires a constant 9-40V DC power supply from the car battery. When the backup battery is full, recharging stops. In stationary mode, the tracker enters power-saving mode (GPS off, internet offline). When movement is detected, it wakes up to normal working mode.

Wire Harness Connections:

• RED or BROWN: 12V/24V Car Battery
• BLACK: GND (Car Body)
• WHITE: ON Signal (Engine Running) - Positive Input. This signal indicates the engine is running. If positive, the tracker uploads location. If open, it stops uploading. If not connected, shock sensor controls uploading.
• YELLOW: Turn off Engine Negative Output (Connect to Relay) - Used to control the engine power supply via a relay. A diode is recommended to protect the driving wire.
• WHITE/BLACK Double Wires: External SOS Button

Caution: Remotely turning off the engine while the car is in motion is dangerous. It is recommended to connect the relay to the start motor wire to prevent the engine from being turned off remotely.

Installation Location: Install the tracker in a hidden location (e.g., under a seat, in the armrest box, under the rear window) where it can receive GPS and 2/3/4G signals. The GPS antenna should face the sky. Test location accuracy after installation.

Internet Vising APN & User Name and Password

To enable internet access for location uploading, set the APN, username, and password via SMS commands. Obtain these details from your SIM card supplier. Commands include:

• Set APN: APN*12345678*apnname
• Set Username/Password: USERNAME*12345678*username*password

Note: If using an M2M SIM card without SMS service, use a normal SIM card to set these parameters first, then switch back to the M2M card.

Back Up Battery & Power Down Alarm

When the tracker's power supply is off or voltage is too low, it sends a power down alarm SMS to authorized numbers, indicating potential removal or power loss.
