5.1 Real time tracking

There are three kinds of tracking mode. User can select setting in the phone APP software
function to choose the working mode.

1. Rapid positioning (1 minute): equipment at 1 minute intervals updates location
information, we don’t suggest choosing rapid positioning model, because the battery
will be lower sooner than standard mode obviously. We don’t suggest selecting this
one.

2. Standard positioning (10 minutes): equipment updates location information
according to the time of 10 minutes interval. We suggest selecting this one.

3. Save electricity positioning (an hour): equipment in one hour time interval to
update location information, the power-saving mode use battery slowly. This one is

good for power saving.
