The main function is to compensate for the poor sound quality of my TV is largely reached. Used with my TV bravia hdmi plugged in, the bar lights along the tv and driver with the TV remote control (vol + and -). One could then believe that you can store the supplied remote. Unfortunately not, oddly all the settings are not saved by the soundbar. Including brightness of the display (which each start is at the bottom), by activating the Bluetooth function (not tested but always on whenever you start off so that I pass it before stopping). However the few acute and sub acute settings (not fine) are recorded well (?). Too bad it could have been convenient. So I remain a little on my hunger. A detail that many probably know but I discovered on the occasion: When the TV is connected to the optical sound bar any increase or decrease in volume adjustment is possible with the TV remote control. At this point everything is done with that of the soundbar.
