7. How to operate
The ST3940,a multifunctional battery-powered mini GPS tracker, is ideal for tracking personal, valuable assets like
merchandises that are delivered by putting it onto an object.
While tracking, it reports location information about the object at a predefined interval and alerts if it detects motion of
the object. Because it is powered by battery, its user should charge the battery fully prior to using and should turn it off
when tracking is finished.
Users are required to set the reporting timing of the device at an interval with more than 10 minutes in order to save the
endurance time of the battery.
