  • All the data and the registries stored in the RAM are initialized when the system (OS) is updated. You should back up the critical data before you start updating. For more details on the data backup, refer to the User’s Manual or visit here.
  • To prevent the battery from running out of power in the middle of the update, make sure that the battery is sufficiently charged. Or, place the BHT on the CU when updating the system.
