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 "Sound Bar Not Compatible" 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).
