Preparations for a firmware update:
After the firmware update has been performed, the camera's menu settings will be reset. It is recommended that users save their menu settings as settings data to an SD card, separate from the one that will be used to carry out the update, before starting update operations. This saved data can be loaded into the camera and the settings can be changed after the update has been completed. For further information on this, please refer to the section in the unit's Instruction Manual titled "Saving and Loading Camera Settings".
