    Other Hardware

    Updating the System Software Version

    Important Notice

    • Use a fully charged rechargeable battery pack (NP-FZ100).
    • Do not remove the battery during the update as the sudden loss of power may render the camera inoperable.
    • It may not be possible to update if the camera temperature is high. Please wait to update until after the temperature drops.

    Step 1: Update the System Software

    1. Insert the memory card that contains the saved system software data into slot 1 of the camera. Only slot 1 will recognize the system software data.
    2. Select Menu → Setup → Setup Option → Version → Body.
    3. Select Software Update.
    4. Select Execute on the system software update confirmation screen. The software version update will start.

      On-screen message:
      • Update? X.XX → Y.YY
        • X.XX: Current version number
        • Y.YY: Newest version number
      Notes:
      • Do not remove the battery or memory card during the update.
      • After confirming the details, you may click Execute.
      • Please scroll down the screen as necessary to view the full text.
    5. When the system software update starts, a black screen will appear and the access lamp will flash 1 time → 3 times → 5 times depending on the progress of the update. The update will take approximately 6 minutes to complete.
      Location of the Access lamp: It's on the bottom right of Rear side.
      Notes:
      • If the system software data copy is incorrect, the message “The target model for the update file is incorrect” will be displayed on the camera monitor.
      • If the access lamp repeats 5 long blinks (0.5-second cycle) and 6 short blinks (0.25-second cycle), or 7 long blinks (0.5-second cycle) and 7 short blinks (0.25-second cycle), the system software may have been incorrectly copied to the memory card.
        • In this case, remove the battery and memory card from the camera, prepare another memory card, and then start over from the Saving the System Software Data to a Memory Card section of this article.
    6. When the update is complete, the camera will automatically restart. After restarting, when the Body update complete screen appears, press OK.
