Hi All, I had an issue whilst trying to pair the Subwoofer to the main LG soundbar unit. It went into Demo mode. Heres what i did to get it out of Demo mode - With the soundbar plugged in, switched on and showing "DEMO" in the display - Simultaneously and hold the "sound effect" button on the remote control and " - " volume button on the soundbar unit. Keep these buttons pressed until you get a reset message on the display and the red power light comes on. Switch the soundbar off and then back on again. (I also had the soundbar showing TV ARC with the HDMI connected whilst conducting this method) . I managed to pair the soundbar and subwoofer prior to this with the soundbar being in Demo and having the HDMI connected with TV ARC showing. I then reduced the volume to" Vol MIN" then held the MUTE button for 3 seconds which displayed Wl Reset and started the pairing process. Hope this helps LG soundbar owners.
