Scheduled Report Mode
For the mode schedule distance report and scheduled mileage report and optimum report, <GPS on
need> must be 0 (Never close GPS chip) or 2 (Never close GPS chip in ignition on state or
movement state) for the function. For the mode scheduled timing report, it doesn’t care whether
GPS works always.
Corner report
It is necessary to set <
GPS on need
> as 0 or 2 for detecting turning point. Because the detection
for turning point is based on heading in GPS position which is not so accurate, it could make
mistake to detect turning point sometimes.
