1) Press and hold the button on the top of your Trax for 5 seconds or until you see the green LED flash in the front of the device.
2) Release the button. After that, the LED in your Trax will flash different colours depending on the connection, GREEN means you have connection to GPS and GSM, ORANGE means that either GPS or GSM (cellular network) connection is missing.
3) To switch off your Trax, press and hold the power button until you see a solid RED light, then release the button.
Important: remember to take your Trax outside before switching it On in order to get a GPS signal faster.
