The sound bar is designed to perform an OTA (Over-the-Air) software update. In order for the OTA to work, the Alto 9+ needs to be connected to your Wi-Fi network. When a new software is available, you will see a notification on the sound bar LED will display <NEW S/W OK/NOT>. Press the Play/Pause/OK button from the sound bar remote to download and install the new software.
