Here's a How-To guide on Samsung's support site:
Also, if you have other 2.4Ghz products nearby (microwaves, cordless phones, etc), that may also interfere with the 2.4Ghz signal from the receiver to the subwoofer. You might check to see that it's not too close to those kinds of wireless components.
The soundbar is working fine but the subwoofer doesnt seem to be working. When i first plugged in the subwoofer's power, the link light was flashing and now the standby light is just staying lit. I pushed autolink on the speaker remote control and the soundbar lit up 3 times along with the tv (samsung 8000 LED).
How can I tell if it's working? Doesn't seem to be making any sound. I am aware that it's known to cut in and out though.
