The guide provides step‑by‑step instructions for checking the current firmware version, extracting the downloaded update files, and copying them to an SD card. It covers both Windows and Macintosh systems, describing how to use a USB cable or a card reader to transfer the files.
After the files are on the SD card, the manual details how to format the card, place the camera in the correct mode, and initiate the firmware upgrade. It also explains how to confirm the upgrade, handle error messages, and safely disconnect the camera once the process is complete. This manual is written in Chinese.
