My soundbar nb4540 always get connected with my neighbour phone and they blast the sound. How can i change the bluetooth code ?

Asked by: Mike1997
This model is not designed with such security measures available. Re-establishing the Bluetooth connection between this system and your own device should interrupt the access by the different user. Deactivating the system should also prevent access when not in use. ^CP

will this work with lg 49 lf5400??????

Asked by: chuk
No it won't. That LG 49LF5400 has no audio out. I can't imagine ANY TV not have any type of audio out, but this TV is one of them. Avoid it if you want to attach a sound bar to it, which I recommend as the sound is limited on it. Should have &quot;Sound Bar Not Compatible&quot; on the box. Very disappointed.

Can the subwoofer be used with another LG soundbar model? I ask as the base unit has recently stopped working, but the subwoofer still works perfectly (on the occasions that the base unit works).

Our offices, in the United States, do not have product information for Germany. In order to obtain such information, it is recommended to check our subsidiary&rsquo;s website, at http://www.lg.com/de/support/kundenservice-kontaktieren.
