In the system settings on your soundbar’s display, you can see the current software version and when it was last updated. Firmware upgrades are automatically offered through your WiFi network. When an update is being installed, you will see the Harman logo on your soundbar’s display and the installation progress will be displayed.
If your system does not have the most recent firmware version, you can download and install the most recent firmware version at Options > Update via the display.
Important note: Please do not power your system on or off or reset it while the software update is being installed.
