The plant was delivered quickly and at first line with expectations while unpacking in relation to its low price. The structure was a little pfriemelig with the cables for drawing, but went. Unfortunately, so far can be the rear wireless speaker not connected to the main unit. Various manuals (web, forums and manual of LG, which does not seem to comply with the German / European conditions) were not successful. For about 6 hours I try to coax the rear speakers to no avail as other power users through settings test tones. WLAN, firmware update, several new-pairing procedures, factory settings, power on / off, change combinations of pressures on main unit and Ferndbedienung with sequences of with / without power, sound settings manually, do not show a success. (I close the boxes but from behind a trial basis at the front, they work.) Meanwhile, though "green" displayed on the radio receiver, but still no sound. The attempt on the specified LG support page (New Registration, raussuchen of device heading, enter SN to residential details, authentication, forwarding to customer form for Support / Installation and after two problem input then each of the Note that this just completed form not currently were available ... Sorry, but that needs to be better in every respect. I hope now as wholesale and corporate client on an acceptable response from LG / Amazon to solve the problem. As long as there is only 1 star ( or in thoughts zero star). Unfortunately, you can like it in the office would be possible for us, not just connect the rear speakers directly wired to possibly. the point of failure ruled out radio receiver.
