I recently purchased the SWA-9000s rear speaker kit after two Samsung agents told me it would work with my HW-KM45 soundbar system.
I turn off the soundbar and hold mute for 5 seconds to get the set id to flash. The subwoofer and rear speaker kit both flash their blue lights after holding the pins in for 5 seconds. When I turn the soundbar back on, the rear kit does not connect but just continues to flash.
