Updating the pre-installed software
There are three ways to update the pre-installed software of the home audio system.
Update method 1: Automatic update via the Internet
The home audio system detects if a new version of the software is available.
Update method 2: Manual update via the Internet
After the home audio system informs you that a new version of software has been detected, update manually.
Update method 3: Manual update via a USB flash drive
Download the update file from the Internet, then use a USB flash drive or similar to install the file to the home audio system.
Manual update via a USB flash drive (when the update via a network has failed)
If update method 1 or 2 has failed, perform this procedure.
