How to set the device back to factory default

    Normally the devices do not have hardware button to do factory default setting. We can do this through software :

        (1) Connect device with pc.

        (2) Open communication software.

        (3) “Add device” ->“Synchronize time”-> “Initialize device”(NOTE:  if you want the datas in the device, pls  back up all  the datas first.)
