In the System Settings or About options, find the "Software Update" or "System Upgrade" option.

Click the "Software Update" or "System Upgrade" option, and the system will automatically detect the latest updated version.

If a new version is found to be available, you will be given the option to download and install it. Follow the system prompts to download and install.

Wait for the system update to complete. During the update process, the price checker may automatically restart or some prompt messages may appear. Please follow the system prompts.

After the update is completed, restart the price checker and check whether the system is running normally.

Therefore, it is recommended to refer to the price check machine user manual or contact the manufacturer's technical support to ensure the correctness and accuracy of the operation. At the same time, before performing a system update, it is recommended to back up important data to prevent unexpected data loss during the update process.
