<Note>:
1. There might be a case that a device user does not want to utilize functions of motion sensing of the device,
which means that a case that the value of <VI_ON_THRES> is zero (0). In such a case, the user can adjust
the time period of <GPS Module On> in order to enable the device to catch GPS signal of satellites to better
facilitate the time period of <GPS Fix>. In such a case, the user can set a Value of time period of <GPS
Module On> ranging from 10% up to 80% of the interval of Parking Mode. If this Value is set higher, life time
of the battery gets shorter. Before you make a decision, therefore, you need to think about how high/low this
Value should be. You need to be selective in setting this Value in consideration of how you practically use the
device.
2. The default is 33%. The GPS module of the device is On for 60 seconds, which is 33% of the Default Parking
Interval (i.e. 180 seconds). Maximum time period of <GPS On> is between minimum 1 minute and maximum
10 minutes.
3. Sometime, you may need to change the existing Parking Interval. In such a case, the saved value of the <GPS
On Percent> has an influence on the time length of <GPS On>. Therefore, you need to think about it and may
change the value of <GPS On Percent> if you need to do so.
4. It is reported that some users utilize the device to monitor just the vehicle’s movement without utilizing Motion
Functions of the device. Some areas may have a problem in making the device to fix GPS. In such a case, you
can get better location information about the device if you change the value of this parameter depending upon
the area where you utilize the device.
