Caution:
- Please use an SD/SDHC/SDXC memory card that is 512MB or greater to perform the firmware update.
- Firmware version 1.0.5.1 is for updating EOS R5 C cameras running firmware version 1.0.0.1 - 1.0.4.1. If your camera's firmware is already version 1.0.5.1, it is not necessary to update the firmware. Once the camera is updated to the latest version, it cannot be restored to a previous version.
- Please refrain from loading menu settings generated using the most recent firmware version to a product running an old firmware version, as doing so may affect camera operations.
- Firmware update must be performed in VIDEO mode.

Preparations for a firmware update:
After the firmware update has been performed, the camera's menu settings will be reset. It is recommended that, prior to starting update operations, 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. 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."
