Q：Positioned by GPS / LBS ?
A：GPS called“Global Positioning System”,GPS device can be positioned by GPS
satellite outdoor. Device also can be positioned by base stations of operator
which call LBS ,mainly for assistance positioning.
Q：Location is not accurate?
A：If need accurate positioning, use device outdoor where GPS signal is good and
start GPS tracking mode.
Device indoor mainly positioned by LBS, the accuracy lower than GPS
Q：Standby time can be longer?
A：Device need Internet connection. Standby time will be different by different using environment and working mode.
A：The conditions below results in offline.
① No balance or No SIM ② No GSM or GSM signal is weak ③ Battery runs out
