On the back is a sticker pointing to the power button (on the top side). Hold power for 3 seconds to turn on. All lights will come on and start to flash, that is it. After 5 mins it will send its first location update.

To power off, hold power again for 3 seconds, and a red light will come on and stay on for up to 2 mins, then all lights will go out. It is then off.

If for any reason you need to restart the tracker, then follow that process above.

The button on the front of the device is SOS. If you share a mobile phone number, that phone will get an SMS if someone pushes the SOS.
