<Notes>
1. Driving or Parking is decided by Motion Sensor. If VI_ON_THRES is equal to zero, it cannot recognize
‘driving’. Please do not forget that the ST3940 may show you a bigger distance than the real one while
the vehicle is parked, if you make an optional configuration to enable the device not to check motion.
2.
To use the ‘DEEP SLEEP’ option, ‘PARKING_INTRV’ should be one hour or more than one hour.
3.
If “DEEP SLEEP” option is enabled, ‘the report of distance’ will always be ‘0’.
4. The device can be used to do tracking for a fixed asset. In this case, the following table shows how long
the endurance time of the battery lasts.
