Keep your V31 up to date to ensure optimal performance and access to the latest features. Details about the changes are provided in the "UPDATE HISTORY" section on the System Program page.

You can update the V31 system program via Wi-Fi or an SD card. Choose the method that best fits your environment.

Important

If you are updating from Ver.1.02, a factory reset is required so that the changes introduced in Ver.1.03 can take effect. If you want to restore your current settings after the update, back them up to an SD card before updating.

If you are updating from Ver.1.03 or later, a factory reset is not required (current as of December 2025). However, creating a backup is still recommended to protect your current settings.

For details, refer to “Backing up to an SD card (SAVE)” in the V31 Reference Manual.

Updating via Wi-Fi

When your V31 is connected to Wi-Fi, a message appears automatically when a new system program is available (factory settings). Refer to “Updating the V31 via Wi-Fi” in the V31 Reference Manual to perform the update.

To check the currently installed version, go to [MENU] > SYSTEM > INFO.
