Class 10 is default set when the module work at data translation mode, the module can also work
at class 8 set by AT command.

6.4.2 The current consumption of the GPS part

To save more current consumption, we suggest the user to design their system in one of the two
modes: 1. Power Down mode; 2.Push-To-Fix mode
