Normal pairing is automatic, and happens when you first switch both devices on. If pairing does not take place automatically, or you have to force new pairing, here is what to do: Turn on the soundbar and the subwoofer. If the connection is lost, the LED indicator on the subwoofer blinks slowly. Second, press the CONNECT button on the subwoofer to enter pairing mode. The LED indicator on the subwoofer blinks quickly. Third, press and hold the DIM DISPLAY button on the remote control for 5 seconds, followed by short press on BASS+, and BASS- button in sequence. Panel display will show “PAIRING”. If pairing succeeds, the LED indicator on the subwoofer lights up, and the soundbar display will show "DONE”. If pairing fails, the indicator on the subwoofer blinks slowly. Lastly, if the pairing fails, repeat the steps above. If you have continued trouble performing the pairing, please try to switch off all wireless devices in the home, then try again. This means routers, TV sets with wireless functions, telephones, computers etc. Since overcrowding on the 2.4 GHz frequency now often causes problems, eliminating all this activity makes space for the Bar to establish its connection, and you should be able to pair without problems. Afterwards, you can switch your devices on again. Often, all will now work fine, and if not, you will know which devices are doing the interference.
