Select Menu → Setup → Setup Option → Version → Body.
The system software version will be displayed.

Notes:

If the system software version is Ver. 4.00, the update is not required.
When updating from Ver. 1.32 or earlier, you need to update to Ver. 2.01 first. Please update to Ver. 4.00 after updating to Ver. 2.01.
If you try to update this version without updating to Ver. 2.00 or Ver. 2.01 first, an error will occur and you will not be able to update the software.
If the Date/Time setting screen appears when you turn on your camera, be sure to set the date and/or time to the correct values.

Saving the System Software Data to a Memory Card

IMPORTANT: Make sure there is only one BODYDATA.DAT file on the memory card.

Click the Download button.
After reading the disclaimer, click Download.
Save the file to your computer.
Insert the formatted memory card into the computer.
Save the BODYDATA.DAT file in the root directory of the memory card. Do not change the file name.

Before formatting, copy the data to a computer or other device.
- Once you format the memory card, all the data recorded on the memory card will be deleted and cannot be restored.
Please refer to the instruction manual of the camera for compatible memory cards.

Other Hardware

Power source for the camera: Use a fully charged rechargeable battery pack (NP-FZ100).
Note: The update can only be performed when the battery power level is 51% or more. We recommend you use a fully charged battery.
Detach the vertical grip from the camera before updating the system software.

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

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.
Select Menu → Setup → Setup Option → Version → Body.
Select Software Update.
Select Execute on the system software update confirmation screen. The software version update will start.

On-screen message:

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), it is possible you have not updated from Ver. 2.00 or later, or 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.
When the update is complete, the camera will automatically restart. After restarting, press OK on the “Body update complete”.
