To find the status of your Whistle GPS tracker, simply press and release the Power button.


  • If the LED status indicator flashes 4 times, the tracker is on, with sufficient battery power
  • If the LED flashes twice, the tracker is on, but has a low battery charge
  • If the LED does not flash or light up, the tracker is off or the battery is dead
