Initial Setup

Installing the SIM card: Before installing or removing the SIM card, please power off the tracker. Remove the rubber seal on the side of the tracker to access the SIM card tray. Press the yellow button with a tool to eject the tray. Place the SIM card in the tray making sure SIM card metal contact pins are facing up. Insert tray back into the Tracker and replace the rubber seal to cover the SIM card socket.

Charging the Tracker: We recommend using the supplied 5V DC OEM charger only to recharge the tracker. Using an incorrect power supply may cause damage to the tracker and void your warranty. Insert the USB connection into a power or car adapter. If the LED on the adapter is RED, it means it is charging, if the LED on the adapter is GREEN, it means the recharging is finished. This will take about 8-10 hours (with exception to the first charge of 24 hours). The tracker can also be connected to a car battery using an external power adapter (9-30V input 5V output). Insert the external power adapter output wire to the tracker charging socket and connect the external power adapter input to the car battery (9-30V). Once the battery is fully charged, the tracker will stop charging and use the external power adapter for continued operation, the built-in battery will only be used for backup.

Power ON and OFF: When the power is OFF, press the “ON/OFF” button until the green LED is ON, then release the button. The tracker is now powered ON. Green and Red LED’s will flash as per details below. When the power is ON, press the “ON/OFF” button till the Green LED Flash fast, and then release the button and press the ON/OFF button 3 times, the tracker will turn off. If the battery is flat, recharge the tracker and the Tracker will power on automatically.

Send SMS/Text message commands to the Tracker SIM service number from a mobile phone. The default SMS Command Password for the 3G Model is 123456 or 4G Model is 12345678. If the password is incorrect the tracker will respond, “Wrong Password”. If the command is incorrect the tracker will respond, “Bad Command”.

Access Point Name: If the APN is not set correctly, the tracker cannot upload its location to the server (Red LED flashes twice).
