Technical Information

Update the BHT-1200-CE/BHT-1100-CE system (OS) using LAN/WLAN

Read this first

  • 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.
  • The power cannot be cut off even with the power key during the update process (while the system software is being written onto the flash memory). To use the BHT, you should wait until the update is completed.
